David Bailey (CEO)
Thanks, Tripp. Good morning, everyone, and thank you for joining us on our second quarter 2023 conference call. As we start all earnings calls, I'd like to begin by highlighting that we helped a record 21,000 children in the second quarter of 2023, and since inception, we have now helped over 670,000 kids. Helping more children remains the best measure of our success. In the second quarter of 2023, we generated record-high revenue of $39.6 million, representing growth of 20% compared to the second quarter of 2022. Despite a challenging operating environment within children's hospitals, we continued growing our business by taking market share and are encouraged by the momentum we've generated in the first half of the year.
We are proud to have again generated growth of 20% against the strongest comparable period of the year, while deploying $9.2 million worth of set. Altogether, we are positioned favorably for the second half of the year. As expected, we are experiencing gradual month-by-month improvements in the inpatient surgical environment, where nearly all of our procedures are performed. As you may have read, many insurance companies have reported increased overall volumes, but lower inpatient procedures. Our observations are consistent with this recent commentary, and we continue to feel the impacts of lower than historical average volumes in the children's hospital environment. Nevertheless, execution of our historically successful strategy is leading to consistent quarter-over-quarter share gain and is producing sustainable growth regardless of market conditions.
We are reiterating our revenue guidance of $148 million-$151 million, representing growth of 21%-23%. Moving to our revenue segments. In the second quarter of 2023, we generated total trauma and deformity revenue of $27.5 million, representing growth of 22% compared to the prior year period. Revenue growth in the quarter was led by strong performances in deformity correction and Pega products. The quarter saw a record ex fix performance from our external fixation portfolio, driven by Orthex, the recently launched pre-planning software, and the new DRIVE Rail system. PediFoot, the DFOS plating system, and PediPlates, a system we first launched in 2008, all were particularly strong in the quarter.
Although the trauma franchise grew slightly slower than it has in the last few quarters, PNP Femur and Cannulated Screws continued their dynamic growth trend. Additionally, Pega product sales have been better than we ever expected, nearly doubling in the U.S., and we are just now seeing the early returns of additional deployed inventory. International Pega revenue, while strong, has yet to reach its full potential as we are working through several conversions of stocking distributors to our agencies. We expect this to become a strong tailwind and a solid source of growth in the second half of 2023 and beyond. Overall, strong Pega revenue will continue to benefit the company for the next several years, and we are very pleased with how this is trending.
Speaking of Pega, in June, we announced the limited launch and first procedure using the GIRO system, developed by the Pega R&D team in Montreal. This unique tethering system utilizes guided growth, providing surgeons a new way to treat limb deformities without the need for osteotomies. This system builds on our legacy of innovation and illustrates another reason why we are so pleased with the Pega acquisition, as it strengthens the OrthoPediatrics R&D pipeline. Lastly, on the trauma deformity R&D side, we are eagerly anticipating the FDA approval and beta launch of our PnP tibia system, which will be a first of its kind pediatric rigid tibial nailing system, modeled after our market-leading and largest trauma product, the PnP femur. PnP tibia will serve as a follow-on to our largest and fastest growing trauma product, PnP femur, and we are extremely excited about its growth potential.
If we see its successful approval, we are targeting the first case late in the third quarter. Within the T&D business, our nonsurgical specialty bracing business continues to perform well, highlighted by MDO clubfoot bracing. In the second quarter, the nonsurgical specialty bracing business launched the clubfoot MoveBar, expanding the MDO portfolio, which has received a very positive customer response. We are eagerly awaiting the launch of several additional products from our team in Iowa, as well as the much-anticipated DF2 femur fracture brace, which recently proceeded to final validation and is launching this month. With respect to MDO, the addition of new products in existing markets and expansion into new markets is bolstering growth. Now, slightly more than a year into launch, we have validated our thesis that OrthoPediatrics can and will build a large and profitable business in the specialty bracing space.
Our customers are presenting us with several unmet needs in the areas that can truly impact care for kids, and we're planning to further invest in R&D that can help deliver much-needed solutions. Our specialty bracing business represents the most capital-efficient opportunity for growth in our portfolio and reduces the need for continual capital deployment. While we are very early, we see this business growing to in excess of $100 million in the next several years, providing a new and exciting growth opportunity. Moving to the scoliosis business. In the second quarter of 2023, we generated revenue of $10.9 million, representing growth of 16% compared to the prior year period, driven by a continuation of our strategy of promoting the combined strength of ApiFix, RESPONSE, and 7D placement.
The second quarter started uncharacteristically slow, but dramatically improved in May, and the usual summer seasonality started to show up in June, which we expect to carry forward throughout the summer. We also expect the multiple 7D units placed in Q2, along with our strong consignment and sales pipeline, to bolster Scoliosis growth in the second half of the year. We're pleased to see the value proposition of the combination of ApiFix, 7D, and RESPONSE, comprehensively addressing surgeon needs and driving market share gains. Again, total users in Q2 increased meaningfully compared to the prior year period. Enabling technologies, such as additional 7D placements and ongoing FIREFLY usage, is driving share gain through our RESPONSE Fusion platform, and ApiFix non-fusion is helping expose new surgeons to all our Scoliosis technologies, leading to new customer acquisition.
ApiFix usage is growing, both in terms of new users and increases among existing users. Our scoliosis growth continues despite an absence of revenue from three of our largest sites, as those surgeons have transitioned to new practice locations. We expect this will normalize in the coming quarters. We continue to make progress on the development of ApiFix's non-fusion clinical data, which we believe will lead to increasing KOL support and podium presence. For example, 1-year data of 148 patients was presented from the podium at POSNA by Dr. Jeff Haft, that showed just 5 of 148 ApiFix patients went on to fusion and a low device-related reoperation rate of just 6.7%. We're pleased to see these results, especially given that these are the first cases done in the U.S.
As we learn more, work through the learning curve, and make further advancements on the implant and technique, we expect results will get even better in the coming years. Given the early data, we expect to see several additional publications in the quarters to come. On the R&D front, in Q2, we launched several key products and line extensions, including RESPONSE Power, RESPONSE Power Torque, RESPONSE cannulated Screws, and RESPONSE Derotation Instrumentation. During the quarter, we performed several surgeries with each of these new products and received positive surgeon feedback, with especially glowing commentary about our power systems. Lastly, we continued progress on our EOS suite of products and achieved major milestones on our EOS guided growth system during Q2. We expect FDA submission of this key product by year-end. Moving on to international.
In the second quarter of 2023, we generated international revenue of $10 million, compared to $8 million the prior year period, delivering 25% growth, primarily driven by strong performance with our legacy products, slightly offset by slower MDO growth due to timing of stocking purchases by new MDO distributors that were very high in Q2 of 2022. Agency market sales in Europe were particularly strong, signaling a normalizing surgical environment, and progress in our German direct sales model is a bit ahead of schedule. We are pleased with this rebound and expect the strength to continue in the second half of this year. While small at this time, we are at the very beginning of launching our Scoliosis business in Europe and expect this to positively impact revenue as early as 2024.
Additionally, sales of Pega products are just starting to contribute to revenue growth outside of the U.S. as we begin to transition stocking distributors to our agencies in 14 markets. Once complete, we expect to see very similar results to that of the U.S. and believe this will be a major tailwind to international growth in the second half of 2023 and beyond. Additionally, we've worked toward expanding our international distribution footprint, and I have a few updates to share. This quarter, we signed 2 new stocking distributor agreements. The first is for distribution of our scoliosis product in Brazil, and the second is an agreement to distribute the broader OrthoPediatrics portfolio in Peru. These distribution agreements will strengthen our international presence, and we expect them to contribute to our growth in the second half of the year and beyond.
Lastly, we've received positive audit feedback related to the long process of EU MDR compliance with OrthoPediatrics products and expect to achieve EU MDR approval in the coming year, thus opening opportunities to launch several new-to-Europe products in 2024. It is our intention to have the full suite of products compliant in 2024. That brings us to surgeon training and education. To support our goal of helping advance the entire field of pediatric orthopedics, we continue to prioritize outsized support of pediatric orthopedic clinical education and training. This pillar of our strategy is central to who we are as a company, and we believe signals to our customers that we're different than our competitors. Throughout the second quarter, OrthoPediatrics held over 90 events, which included training sessions and educational programs reaching over 1,200 healthcare professionals.
In May, we unveiled our new Emerald sponsorship at POSNA in Nashville, solidifying our position as the leading supporter of the surgical society. The 2023 meeting saw record attendance, and the society continues to grow in both membership and prominence in pediatric healthcare. Through our long-term commitment to POSNA, we are providing ongoing support of rigorous training events for surgeons and other healthcare professionals, awarding educational grants and scholarships, and have founded a women's affinity group to support our combined efforts in diversity, equity, inclusion, and belonging across the subspecialty. Additionally, we hosted interactive, case-based seminars to discuss novel treatment options in adolescent idiopathic scoliosis, utilizing our ApiFix technology. We celebrated our colleague and friend, retired Chief Medical Officer, Dr. Peter Armstrong, as he was inducted into the POSNA Hall of Fame. Lastly, before I turn it over to Fred, I'm delighted to welcome Dr.
George Dyer to our board of directors. He is a renowned orthopedic surgeon at Brigham and Women's Hospital in Boston, as well as being Associate Professor of Orthopedic Surgery at Harvard Medical School. For 10 years, George was the program director of the Harvard Combined Orthopaedic Residency Program, one of the largest orthopedic residency programs in the country. His deep experience will allow him to contribute to our clinical training program, as well as our product portfolio strategy. With that, I'll turn the call over to Fred to provide more detail on our financial results. Fred?
Fred Hite (COO and CFO)
Thanks, Dave. Our second quarter 2023 worldwide revenue of $39.6 million increased 20% compared to the second quarter of 2022. Growth in the quarter was driven primarily by continued share gains across our legacy portfolio, as well as growth of our nonsurgical specialty bracing business. U.S. revenue was $29.6 million, a 19% increase from the second quarter of 2022. Growth in the quarter was delivered across our trauma and deformity product lines, including our nonsurgical specialty bracing business and across our Scoliosis product lines. We generated total international revenue of $10.0 million, representing growth of 25% compared to the second quarter of 2022. Growth in the quarter was driven by strong performance within our Scoliosis products, as well as our trauma and deformity product lines, including the nonsurgical bracing.
In the second quarter of 2023, trauma and deformity revenue of $27.5 million increased 22% compared to the prior year period. Growth in the quarter was driven primarily by share gains across our entire portfolio, with strong contributions from deformity correction. In the second quarter of 2023, scoliosis revenue of $10.9 million increased 16% compared to the prior year period. Growth was primarily driven by the combined strength of ApiFix, RESPONSE, and 7D. Finally, Sports Medicine/Other revenue in the second quarter of 2023 was $1.2 million, which increased 23% compared to the prior year period. Turning to set deployment, $9.2 million of sets were consigned in the second quarter of 2023, compared to $3.4 million in the second quarter of 2022.
Year to date, we have deployed $12.2 million compared to $7.3 million in the first half of last year. The increase was driven by significant new product development deployments, significant Pega deployments, as well as multiple consigned 7D units. Touching briefly on a few key metrics. For the second quarter of 2023 and 2022, gross profit margin remained constant at 75.9%. Total operating expenses increased $6.9 million or 24% to $35.6 million in the second quarter of 2023. The increase was primarily driven by the addition of incremental personnel-related expenses required to support the ongoing growth of the company, as well as increased sales and marketing expenses driven by the increase in revenue.
Sales and marketing expenses increased $0.7 million, or 6% to $13.2 million in the 2Q 2023. The increase was primarily driven by increased sales commission expenses.... General and administrative expenses increased $5.1 million, or 35% to $19.7 million in the 2Q 2023. The increase was driven primarily by an increase in non-cash G&A expenses, including depreciation, amortization, stock-based compensation, as well as some additional personnel related expenses required to support the ongoing growth of the company. Research and development expenses increased $1.0 million or 60% to $2.8 million in the 2Q 2023, driven by an acceleration of new product introduction efforts.
Total other income was $2.3 million for the second quarter of 2023, compared to $3.0 million for the same period last year. We reported Adjusted EBITDA income of $2.3 million in the second quarter of 2023, compared to $2.1 million for the second quarter of 2022. We ended the second quarter with $94.8 million in cash, short-term investments, and restricted cash. We continue to maintain strong cash position, as well as $50 million available to us on our line of credit. Turning to guidance, we are reiterating our expectation for full year 2023 revenue to be in the range of $148 million-$151 million, representing year-over-year growth of 21%-23%.
Lastly, we continue to expect around $25 million of new sets deployed in 2023, representing a year-over-year annual growth of 24%. Additionally, we continue to expect to generate between $3 million-$4 million of Adjusted EBITDA in 2023. I'll now turn the call back over to Dave for some closing remarks.
David Bailey (CEO)
Thanks, Fred. I'd like to remind you that OrthoPediatrics has systematically put into place an impressive array of long-term growth drivers that will continue to produce annual growth of 20% or more for years to come. New product launches, set consignments, surgeon education, and great technologies such as Orthex, ApiFix, and 7D are driving surgeon conversion and market share gains. Acquisitions such as MDO and Pega Medical will also continue to grow rapidly. Further, we're building a new non-surgical specialty bracing franchise, while also investing in digital health solutions that create new and exciting growth opportunities for the future that are profitable and capital efficient, while helping more and more kids on a global basis. In closing, I'd like to thank our surgeon partners and all of my associates for their tireless effort to improve pediatric healthcare around the world.
I'd like to thank you, as shareholders, for supporting our cause. Thank you.

As a reminder, to ask a question, please press star one one on your telephone and wait for your name to be announced. To withdraw your question, please press star one one again. Please stand by while we compile the Q&A roster. The first question comes from Ryan Zimmerman with BTIG. Your line is open.
Ryan Zimmerman (Managing Director and Medical Technology Analyst)
Hey, guys. Can you hear me okay?
David Bailey (CEO)
Yeah, loud and clear.
Fred Hite (COO and CFO)
Morning. Morning, Ryan.
Ryan Zimmerman (Managing Director and Medical Technology Analyst)
Morning, morning. Good to, good to speak with you guys. Just want to ask a couple of questions, if we could get started here. You know, just about the, the environment in the, in the pediatric hospitals, and, and it sounds like it's improving, but I guess I'm curious kind of, you know, why it still remains challenging in your view, kind of what they're doing to address it, and kind of, you know, what the expectation is for, you know, quote, unquote, "normalization" in the pediatric space?
David Bailey (CEO)
Yeah, good question. Yeah, we, it's still not normal, certainly. We think that's just due to, you know, specialized staffing, particularly, you know, in the more complex procedures, we're not seeing the same throughput. That's pretty consistent with what we've seen now for, you know, a better part of a year. That said, I think we've kind of moved beyond this in terms of not wanting to dwell on it. I mean, we have to continue to execute the things that we do to drive growth. I think, you know, in the quarter, we saw really nice new customer acquisition that, that has really, you know, obviously, producing 20% growth, we offset a lot of some of the volumes that just, just weren't normal in some of our major accounts.
I think this is improving, Ryan. I think we're seeing this improve month to month as these children's hospitals are staffing up. You know, obviously, you know, we were just pointing to the reports that are pretty consistent with what we're seeing, that the outpatient environment is very strong, and we do very little of our surgery in the outpatient environment.
Ryan Zimmerman (Managing Director and Medical Technology Analyst)
Right
David Bailey (CEO)
... as you know, and the inpatient environment is a little weaker. I think when we look at our account by account, particularly places where we have really high share, we see that very clearly. Now it's just a matter of, are we onboarding new customers fast enough to offset that? As this improves, and again, it will, you know, maybe we have a couple more quarters here where this is a gradual improvement, you know, we'll be in a spot where, you know, just a better spot. Overall.
Ryan Zimmerman (Managing Director and Medical Technology Analyst)
Yeah
David Bailey (CEO)
... I think we've tried to point it out, but not dwell on it. You know, we got to move forward.
Ryan Zimmerman (Managing Director and Medical Technology Analyst)
Yeah. Fair, fair enough, and appreciate that. Maybe just you laid out a ton of new products, and there's a lot to kind of chew on, I think, for investors as we think about the back half of the year and then into 2024. A couple of things that stuck out to me, Pega deployment and penetration. Pega doubled in revenue, it sounds like, in the U.S. I guess, you know, good results. What do you think you're at in terms of penetration of Pega and kind of where can that grow to? You talked about MDO being kind of this huge opportunity longer term. You know, do you think of Pega in a similar manner?
Then, you know, the second question to all of this in terms of the portfolio is the scoliosis portfolio complete in your view, with, with the combination of 7D, ApiFix, and RESPONSE? Just curious, kind of, you know, what you're thinking is there as well. Thanks for taking the questions, guys.
David Bailey (CEO)
Yeah, good questions, Ryan. Yeah, it's the Pega business in the United States nearly doubled since the time of the acquisition, so I want to just clarify that. We're definitely seeing a lot of adoption of Pega products. I think it's clear that the US selling organization is impacting that, far greater impact by the US selling organization than deployed inventory. You know, a lot of that deployed inventory just hit in Q2, so we're not necessarily seeing a ton of the pull-through because of the deployed inventory. I would say in terms of share, in the United States, the FD product has a really high share. But what we're seeing is, because it was limited access to the products, we're seeing the user profile of the products expand.
More indications are being treated with the FD Rod than I think were before, when surgeons struggled to get it. You know, with respect to the rest of the products, you know, as we've said, there's six or seven products there. Six of them really haven't seen the light of day in the U.S. or international markets. You know, you point to all these new product launches, and you're right, but we're trying to pace all those new product launches with the new things that are going on with Pega, because these products that are coming out of Pega to our customers are new to our sales force and new to our customer as well there.
I guess that's why we have a lot of confidence that now as Pega, you know, we're a year into this, and we see the next several years, this opportunity with Pega to continue to grow well in excess of 20% yearly. Then, you know, we point out the international side of the business, where we're going through a lot of transition from where they were only stocking distributors internationally. We're transitioning some of those stocking distributors in these 14 agency markets to OP agencies. You know what that, you know, results in. It's a doubling of revenue.
Ryan Zimmerman (Managing Director and Medical Technology Analyst)
Right
David Bailey (CEO)
... in those markets. It allows us to consign inventory. Super bullish on where that can take us. It's not, you know, just a back half of the year thing. I mean, we see this going on for another several years. Probably not at the macro level, as big of opportunity as we see for the nonsurgical specialty bracing business. I mean, we, you know, we, we acquired MDO with the intent to make it kind of the launch of a new platform of growth for us in what we would consider a near adjacency in pediatric orthopedics and nonsurgical specialty bracing. As we've done that, it is very clear that there are growth opportunities all over that market and opportunities with very limited competition, good reimbursement, and, you know, doesn't take capital as much capital to deploy there.
Again, not purely a second-half thing, but I think as we get into 2024, 2025, we see the opportunity for this non-specialty bracing business to really, really accelerate for the next several years. Lastly, on the Scoliosis side, I, I don't think the product portfolio is fully complete. You know, we have three different projects right now on the R&D, in R&D that we're working on, on EOS, so early onset scoliosis. That's an area of the market which we estimate is about 15% of the Scoliosis market that really is untouched by our product portfolio, and those areas are very complex. It's very complex surgery with the top KOLs and the top institutions.
As we launch products in that space, you know, probably first product we'll see is our pelvic Rib and Pelvic Fixation System, and then the guided growth system that I mentioned. You know, we expect those products to obviously drive new, you know, penetrate that 15% of the market. But much like we're seeing with ApiFix and 7D, we expect that to pull us through and pull us into a lot of major institutions that, you know, are just dabbling with our products now.
Ryan Zimmerman (Managing Director and Medical Technology Analyst)
Got it. Thanks for taking the question, Dave. Very helpful.
David Bailey (CEO)
You bet.
Operator (participant)
Please stand by for our next question. Our next question comes from Matthew O'Brien with Piper Sandler. Your line is open.
Matthew O'Brien (Managing Director and Senior Research Analyst)
Morning. Thanks for taking my question. Dave or Fred, can you just drill down a little bit more on the domestic business in the quarter? It was a little bit softer than Q1. I know you still got some headwinds. How meaningful are those headwinds? Can you quantify it at all? I know you said deformity was a little bit softer than you expected. Maybe just talk about how things built throughout the quarter. Can you delineate the share gains that you're seeing, you know, underlying some of these headwinds that you're facing? You know, if things come back to, to kind of pre-pandemic levels, which I can't imagine they won't, or pre-RSV levels, you know, how, how big a tailwind could that be given the share gains that you're taking?
David Bailey (CEO)
Yeah, yeah. Good question. Thanks, Matt. Yeah, we've been doing this a long time, and I think, you know, an indication that a marketplace is not completely behaving entirely rational is probably what we saw in Q2. You know, when we think about the build, we really, really struggled, and we pointed it out on the call. We struggled in April, and, you know, we just didn't grow the way that we would expect it for, you know, the month. Then we saw this major rebound in May, I mean, a very strong snapback. Obviously, Matt, the people that were You know, our customers didn't leave us in April and stop liking our products.
They came back in May, and then we saw kind of an ease into June in terms of the seasonality, and that's carried forward through the summer, so having a fairly normal summer. You know, when we look at the months, it's choppy, and choppier than what we had seen certainly previous to the pandemic. I guess that's why it gives us a bit of pause. You know, we like what we're seeing, we like the share gain, but even despite a lot of that share gain, you know, we have a month and a quarter that just doesn't look normal or rational. I think that gives Fred and me both a bit of pause to not get out ahead of ourselves, not to be, you know, not to be guiding super aggressively because that, that's, that's just not normal.
I think over the course of the next few quarters, certainly into 2024, things will start to normalize. We were very pleased to see June, we're pleased to see the seasonality in the business. I think there was some question coming into this quarter, particularly against a very difficult comp we had prior, from prior year. We had some concern that could June be as big as it needs to be, given, you know, the staffing issues. It, you know, it wasn't as big as it's ever been in terms of, you know, throughput, but it certainly was big, and it's given way to a really nice summer here for us. You know, we, we haven't counted it all up in terms of what we think is gonna happen when all of this comes back to normal.
You know, you got to think that with more and more customers using more and more products and improving market, you know, we, we like the trend. Again, not sure that it's gonna all explode in Q3, Q4, but certainly the trend is to, you know, 20% growth like we've delivered for years.
Matthew O'Brien (Managing Director and Senior Research Analyst)
Got it. Appreciate that. Then as far as the bracing business, you know, you mentioned a $100 million business eventually. It sounds like more like 25, that's really gonna start to ramp up significantly. Can you just talk about the investment needed, how you build that business to $100 million, and how you do that alongside, you know, the rest of the company that's growing nicely as well? Thanks.
David Bailey (CEO)
Yeah, good question. You know, we see a lot of opportunity on the R&D side. We knew that before we acquired MDO, I think once our customers saw us make that acquisition, and we started seeing the growth that MDO was producing just through the partnership of our people and their people and now us together, it gave us a lot of confidence that we made the right decision. MoveBar came out, we're seeing growth related to that. We got DF2 on the way. DF2 was featured prominently in some KOL papers that were awarded at POSNA for the last 2 years. There's just a lot of buzz around those, those product lines, and there's very limited competition.
We think through, you know, the combination of pretty heavy investment on the R&D side, and when I say heavy investment, these are not particularly costly to develop because of the regulatory requirements are less than our implants. Then, you know, some investment in the selling organization. We feel very strongly that we're gonna be able to build that business and build it pretty rapidly. I think it's gonna contribute in 2024. It's probably one of the factors that will contribute to, you know, continuation of kind of our 20% plus growth pace. But yeah, you're probably right, it gets much bigger in 2025, 2026.
I just, you know, Fred and I just want to point out that this is another area of growth we haven't talked a lot about, but it, it should give investors a lot of confidence that, you know, we've got another, we've got another lever of growth here, in addition to all the things that we're doing on our surgical side, that are gonna continue to produce really nice, you know, revenue growth, profit. Doesn't require consigned inventory, conserves cash. I, I would think that's everything we all have been aspiring towards.
Matthew O'Brien (Managing Director and Senior Research Analyst)
Got it. Thank you.
Operator (participant)
Please stand by for our next question. The next question comes from David Saxon with Needham & Company. Your line is open.
David Saxon (Managing Director and Medical Technologies Equity Research Analyst)
Yeah, good morning, guys, and thanks for taking my questions. I guess first I wanted to ask on ApiFix. I know there's a competitive product launching, so, you know, are you seeing any impact around ApiFix docs trialing that new product? I know you called out new and existing user growth, but just would love to hear kind of what you're seeing from a competitive perspective and also just any update on ApiFix and kind of just the expectations for the year.
David Bailey (CEO)
Yeah. We haven't actually heard. I'm sure it's a fine product. We just haven't heard anybody use the product in the U.S. yet. I'm sure it's happening. You know, we are aware of the product internationally. I think it's been available for a number of years. Listen, I think our position on nonfusion surgery in general is that as other people enter the tethering space, it just drives awareness, patient awareness and surgeon awareness, that nonfusion surgery for pediatric scoliosis is here to stay. It's gonna grow over time. We view the market as fairly embryonic, right, we're gonna see new people enter. No one can compete directly with what we do, obviously, on the posterior side, much easier surgery.
Now when you stack up results, albeit early, 1-year results, but, we stack those kinds of results up with the ease of use of this product. I think that's what's driving surgeons to start adopting the technology. You know, we added a number of new users. We have a number of sites that are applying for their first IRB to start using this product commercially. You know, I, I think this is a continuation. We think we'll see this product continue to grow as the marketplace grows. The more people that enter the market, particularly on the anterior side of the surgical field, probably benefits us, because it just raises awareness. Again, I think we stand by our claim here.
We think this business has, you know, give or take, doubles this year, and probably does that again next year. Yeah, we just really like this and like the results we're seeing.
David Saxon (Managing Director and Medical Technologies Equity Research Analyst)
Okay, got it. That's helpful. Then, just on the OpEx, it was up, I think, mid-twenties, % in the first half versus last year. It, it looks like a lot of that's, you know, R&D behind some new product launches and, and G&A. Like, does that continue, or, or can we see some more leverage in the model, as we go into the back half?
David Bailey (CEO)
Yeah, we'll see some more leverage in the back half of the year. It's really volume dependent, right? As the volume increased significantly, second quarter to first quarter, we get some nice leverage. Dave mentioned earlier, you know, lack of consignment on the non-bracing side, those products are all sold basically through our e-commerce website, so we're not paying a commission on those bracing products, which gives us nice leverage on the sales and marketing side. R&D, we will continue to invest in that pretty heavily. On the G&A side, it's really the stock comp depreciation and amortization that's driving that. We're getting leverage on the cash side of G&A.
Yeah, we should see some leverage continue in the second half of the year and really into next year as we have different growth drivers, I guess, improving the top line.
David Saxon (Managing Director and Medical Technologies Equity Research Analyst)
Okay, got it. Then just a quick model line question. What, what was the inorganic contribution in the quarter?
David Bailey (CEO)
The only impact is Pega. Pega was purchased July first of last year, and that was about a $6 million run rate business, so $1.5 million-ish pre-acquisition.
David Saxon (Managing Director and Medical Technologies Equity Research Analyst)
Okay, got it. Thanks.

Please stand by for the next question. The next question comes from Dave Turkaly with JMP. Your line is open.
David Turkaly (Managing Director and Senior Equity Research Analyst)
Great. Good morning. Can you hear me?
David Bailey (CEO)
Yeah. Hey, Dave.
David Turkaly (Managing Director and Senior Equity Research Analyst)
Just to clarify one up front here, the month-to-month comment, I'm assuming that's typical in Q2, but it may not be. I understand that it sounds like it started slow and got a lot better, is that typical for you in Q2, or is that not typical in terms of how it progresses?
David Bailey (CEO)
Yeah. Yeah, Dave, let me clarify. It, it is typical to see that ramp. I guess what we saw is growth rates, the comparables were not normal, at, at least as it pertains to April. Normally, we see this nice, smooth ramp into June, and then obviously, you know, June, July, August, those are our big months in terms of volume. As we just look at what April did versus what April did prior year, and frankly, what April does prior years for in the past, you know, we're still seeing that chop.
That was what I was trying to point out, is not that there wasn't a steady ramp into the year that was normal, it was just that what we saw in the month was pretty inconsistent with what we historically see in terms of kind of the growth rates that we would see over prior year. We saw almost complete reversal of that in May, where, you know, revenue shot up and carried us into, into the summer. Does that make sense?
David Turkaly (Managing Director and Senior Equity Research Analyst)
Yeah, totally. I, I get it. Thank you for that. As a quick follow-up, you, you mentioned enabling technologies, you know, FIREFLY and 7D, driving even some RESPONSE. I guess I'd just like to get your thoughts on how, you know, your docs are adopting enabling technologies. What you expected, are they more willing? You know, are they conservative, and it, it's taking a little longer? Just any color you could give us in terms of, you know, how that, that, that initiative is, is rolling out. Thank you.
David Bailey (CEO)
Yeah. There's no question that the pediatric orthopedic surgeons, particularly on the Scoliosis side, are keenly interested in enabling technologies, particularly on the spine side. You know, we see a real opportunity for that also on the trauma limb deformity side, which is why we, you know, really like this partnership. We think over time, you know, the partnership with SeaSpine, 7D, Orthofix will allow us to, you know, to potentially get into the trauma and limb deformity side. There's a big demand for that, certainly. I think the demand for navigation with very low radiation for pediatric patients is extremely high. I think one of the things that's held navigation back in the pediatric space is because historical navigation platforms involve so much radiation.
You know, the pediatric patient absorbs a lot of that radiation, and it's not particularly good. Now that there's a solution that is very low radiation, and frankly, it allows people in the operating room not even to have to wear lead, and you know, a long surgery, that's a big deal. I think the surgeon feedback, healthcare provider feedback across the board related to the enabling technologies, particularly 7D, is very high. The only thing that I think we were a bit surprised by is, you know, we have never been in the capital equipment sales market, this is a bit new for us.
Frankly, we were probably a bit naive in terms of how we thought that the hospital environment would allow for purchase or even consignment on contract, some of these units. So we've done a lot of work over the last year or so to put a lot of options in play, and we're starting to see, particularly Q2, and we think, you know, throughout the balance of the next, you know, year to 18 months, a number of these units that we have in sites start to go on contract from a consignment standpoint, and we even have some sales. We have some sales pending, may not happen in Q3, but we're gonna have some capital sales here, we believe in Q4.
And so again, like what we see there, it's probably just, maybe a little delayed in terms of not the surgeon adoption, but the hospital, taking on the, product and getting it going. Does that make sense? Yes, and thank you for that.
Fred Hite (COO and CFO)
Sure.

Please stand by for the next question. The next question comes from Samuel Brodowski with Truist Securities. Your line is open.
Samuel Brodowski (Analyst)
Hey, thanks for taking the question, and congrats on a good quarter. Just the first one, just to put a finer point on it, were May and June sort of back to the normal inpatient census level that you're expecting, or still a little bit of room to go there? Then just relating that to guidance. The second half still assumes that environment's gonna be choppy in terms of patient volumes, right?
David Bailey (CEO)
Yeah. So May and June, the inpatient environment still wasn't normal. you know, I think when we look at the accounts where we would say, Sam, we have nearly 100% share, particularly on elective limb deformity and elective scoliosis, it's pretty easy to measure that. We just look at the volume, total procedures done, revenue generated. What we see in a lot of those big accounts, and, you know, we cite these 3 places that were ApiFix, fix accounts, but they're also scoliFusion accounts. I mean, those accounts were, we had some accounts that were way off comparatively to prior year. Again, it's not, you know, we didn't lose share in those accounts. So, you know, it isn't normal, but it, it, it's better, right? It was better in May and June, and April was kind of an enigma for us.
It was an odd month all the way around. No, we're not signaling that, you know, just that it certainly got better. It still wasn't running kind of full tilt like we would expect it to, you know, in the coming quarters.
Samuel Brodowski (Analyst)
Got it. Thanks. That's, that's helpful. Then just one on, on the international scoliosis. Can you help us think about, you know, how big of an impact that could be, and how much scale do you think you can have in 2024 in international markets with scoliosis? Should we think about sort of the whole portfolio being launched internationally, including ApiFix, or is that more just starting with some of the core products and then going from there? Thanks.
David Bailey (CEO)
Yeah, so, you know, probably, most people don't know, probably, I guess I realized that we essentially sell no scoliosis products in Europe right now. We do sell scoliosis obviously in Australia and in South America, Latin America, and have a good business there. The products, we had never really launched Scoli. Part of this is related to EU MDR, right? Which products and what timing we were gonna get EU MDR approval. So that's why we call that out. As a good pickup, Sam, that we call this out, that there's a number of products in Europe or a number of products in the United States that are very well accepted here in the U.S. that are not sold in Europe because of pending approval related to EU MDR.
We don't know the exact timing of when in 2024 the full portfolio would be approved, but it is a growth driver for us, certainly as soon as that happens, as well as even into 2025 and 2026, where we have a lot of new products that will ultimately get introduced into our largest markets outside of the U.S., scoliosis just being one. I, I don't know if the impact on the scoliosis or the overall business next year, will be huge for Scoli in Europe. It's certainly gonna take some time to build, but it definitely will impact the scoliosis growth rate next year, even if that number's, you know, say, a few million dollars. Now, with respect to ApiFix outside of the U.S., we have actually pulled in accounts post-acquisition.
The bi- the ApiFix leadership previous had had allowed some people to do some procedures outside of the United States, through stocking distributors that we have, in fact, halted because we're trying to capture data and wanna make sure that that data is good. We're a bit in the process of relaunching ApiFix through our scoliosis strategy. Again, we expect to see a very similar dynamic, right? ApiFix brings customers to our product portfolio. We follow that up with RESPONSE and the full portfolio and kind of pull that through. We expect those dynamics to be similar in major European markets. Again, not huge in 2024, but it will have an impact on the growth rate.
Samuel Brodowski (Analyst)
Great. Thanks for taking the question.
