Thanks, Matt. Good afternoon and thank you for joining us. For today's call, I will provide opening comments and the business update, followed by Anshul, who will provide additional detail regarding our financial results and initial 2022 guidance. Let me start with our performance in the fourth quarter and full year 2021. I'm pleased with the team's execution in 2021 as we extended our market leadership position, grew our commercial infrastructure to 150 U.S. sales representatives, expanded exclusive payor coverage to over 160 million U.S. covered lives, and ended the year with a record 690-plus U.S. active surgeons. Our revenue, consistent with our pre-announcement on January 10 for the fourth quarter of 2021, was $25.2 million, representing growth of 14% compared to the fourth quarter of 2020. Despite various COVID surges throughout the year, we were able to generate sequential revenue growth for the third straight quarter. For the full year 2021, we generated revenue of $90.2 million, representing growth of 23% compared to full year 2020. We navigated through the pandemic very well due to consistent and focused commercial execution. Now let me provide some insight into the impact of COVID-19 on our U.S. operations in the fourth quarter and early 2022. Despite the impact of Delta and Omicron, growing demand for our solutions allowed us to deliver sequential monthly revenue growth in the fourth quarter. Based on our booking records in the fourth quarter, approximately 100 cases that had been scheduled were deferred due to COVID in the U.S. This impacted revenue in the fourth quarter by over $800,000. We estimate that Omicron resulted in approximately 40 U.S. cases being deferred in the back half of December, representing approximately $350,000 in revenue. We believe that the execution by our dedicated field organization has been a key differentiator as we managed through the pandemic better than many of our peers. We're also well positioned because approximately 80% of our procedures are performed in an outpatient setting or at surgery centers. Thus far in the first quarter of 2022, we've experienced an increase in the deferral of procedures due to Omicron. Based on our booking records, over 100 cases were deferred in January. These deferred cases represented approximately $900,000 in revenue. Case deferrals in February declined to approximately 40 cases, which gives us optimism that the operating environment is improving. We remain confident based on our prior recovery experience and our ability to recapture the deferred cases over the next few months as the pandemic recedes. Additionally, while anecdotal, based on our conversations with surgeons, we're aware of some surgeons who have built backlogs of three to four months due to the pandemic surges and hospital infrastructure limitations. The resiliency of our performance throughout the pandemic and the record operating milestones we achieved reaffirm that our investments in growth initiatives over the last 18 months are delivering, and they've positioned us to be a much stronger company in 2022. Now let me provide you an update on our growth initiatives as we look to extend our leadership position and drive durable, long-term growth. Starting with sales infrastructure expansion, our sales team remains an important driver of growth as we penetrate our core market and expand our presence in Trauma and Adult Deformity. I'm really proud of our commercial leadership team's effort under the leadership of Tony Recupero to attract high-caliber talent and end the year with a 150-person sales force, consisting of 85 territory managers and 65 clinical support specialists. These numbers translate to a 30% increase in territories in 2021. The dedicated sales team has been a clear differentiator, especially in this unique COVID operating environment as it allows us to remain focused on surgeons and deliver 25% growth in procedure volume in 2021. In 2022, we'll continue to strategically add headcount, by investing in high-quality sales reps to set up the platform to deliver strong and sustainable long-term growth. Additionally, we remain focused on driving sales force productivity by adding to our bench of clinical support specialists. We're targeting ending 2022 with an approximately 170-person sales force, of which 55% are anticipated to be sales territory managers. Moving on to Surgeon Engagement, we ended the year with over 690 U.S. active surgeons who performed at least one case in the fourth quarter of 2021, representing a year-over-year increase of approximately 18% and a sequential increase of 10% from the third quarter of 2021. In 2021, we had over 1,000 surgeons perform at least one procedure in the year. The growth in active surgeon base in the quarter, driven by both new and re-engaged surgeons, reaffirms that our multi-pronged approach to drive surgeon engagement is delivering. Our investments in building a dedicated sales organization, combined with the introduction of TORQ, exclusive coverage of Anthem and UnitedHealthcare, and the expansion of our proprietary Simulator to train surgeons, have provided the ideal foundation for us to engage new surgeons and reactivate previously trained surgeons. Our goal is to grow our active surgeon base by approximately 15% by the end of 2022. Our Simulator technology remains a cornerstone of our surgeon training program. Specifically, over half of our surgeons trained in the fourth quarter were trained using the Simulator. We've continued to experience a steady increase in adoption rate among surgeons who have been trained on the Simulator. With 24 Simulators in use worldwide and approximately 6,000 surgeons to be trained and retrained, we believe we have the infrastructure to drive surgeon engagement and further expand the active surgeon base. As part of our long-term strategy to grow our active surgeon base, we continue to expand our academic programs to educate residents and fellows on primary SI Joint Diagnosis and the degenerative and deformity surgical applications of our solutions. Since the inception of the program, we've held approximately 170 academic programs in the U.S., resulting in the training of over 850 surgical residents and fellows. Turning to Products and Solutions, the strong performance of iFuse TORQ in 2021, reaffirmed that our broadening product strategy is resonating with our customers. In 2021, our initial focus was on targeted competitive conversions to drive adoption and extend our market leadership as a sacro-pelvic solutions company. In 2022, we expect iFuse TORQ to continue to be a tailwind as we accelerate our penetration into trauma, which we estimate to be a $350 million market opportunity. In Adult Deformity, we're excited about the opportunity to build on the success of Bedrock with our second-generation product. We remain on track to launch this differentiated product in the first half of 2022. On the clinical research front, while the pandemic has impacted the pace of enrollment in SILVIA, a two-year perspective, international, multi-center, randomized controlled trial of two different methods for pelvic fixation in adult patients, we made significant progress on enrollment in the fourth quarter, nearing approximately 80% of target enrollment. We expect enrollment to continue through the first half of 2022 and anticipate the primary endpoint results in 2024. Talking about our patient awareness initiative, we focused our investment in targeted digital marketing programs in our fourth quarter to educate and empower patients on their SI journey. To provide some preliminary insights, we have more than doubled the number of potential patients we are engaging through marketing while significantly increasing the referral of patients to surgeons at the end of 2021, compared to the prior year, showing the effectiveness and efficiency of the targeted digital marketing spend. While the preliminary insights are encouraging, we continue to take a disciplined approach to continuously optimizing and focusing our investments across various digital platforms. With that, I will now turn the call over to Anshul to provide more detail on our financial results.

Thanks, Laura. Good afternoon, everyone. Our fourth quarter total revenue was $25.2 million, representing growth of 14%, compared to the prior year period. U.S. revenue was $23.3 million, increasing 13% compared to the prior year period. International revenue was $1.9 million, increasing 28% compared to the prior year period. Even with the multiple surges in the quarter, resulting in approximately 100 case deferrals in the U.S. and pressure on Europe case volumes in December, we delivered steady sequential monthly growth in worldwide procedure volumes with December being the highest case volume month in company history, reaffirming the underlying momentum in the business. Gross margin for the fourth quarter of 2021 was 87%, compared to 90% in the corresponding period in 2020. Gross margin in the fourth quarter was impacted by an increase in cost of operations to support the growth of the business. Operating expenses increased 29% to $35.8 million in the fourth quarter 2021 as compared to $27.7 million in the prior-year period. The increase was driven by higher sales and marketing costs related to increased sales hiring, higher travel costs, research and development expenses, and increased stock-based compensation. Our net loss was $14.5 million or $0.43 per diluted share for the fourth quarter of 2021 as compared to a net loss of $9 million or $0.28 per diluted share in the prior year period. As of the end of the quarter, our cash and marketable securities were approximately $147 million and long-term borrowings were approximately $35 million. We believe we are well positioned from a liquidity standpoint to support our strategic priorities that will allow us to create long-term growth and shareholder value. Moving to guidance. We are entering 2022 with several structural tailwinds, including increasing underlying demand, a productive sales force, growing surgeon engagement, near-universal coverage in the U.S. and a growing portfolio of highly differentiated products. However, we remain cognizant of the unique external operating environment due to COVID-19 and its impact on elective procedures as well as healthcare infrastructure and staffing levels. Our 2022 outlook is highly sensitive to assumptions on a steady global recovery which anticipates case scheduling and elective procedure levels normalizing throughout the year. For 2022, we expect annual revenue to range between $106 million to $108 million, representing year-over-year annual growth between 18% and 20%. The guidance reflects the assumed impact from Omicron variant in the first quarter of 2022, which we expect will result in mid to high-single digit revenue growth in the first quarter of 2022 when compared to the first quarter of 2021. We expect the annual gross margin for 2022 to be in the mid to high 80% range. The annual gross margin range assumes a normal low-single digit ASP decline based on site of service mix and procedure mix at a higher depreciation of instrument trays based on our investments in 2021. With that, I will turn the call over for questions. Operator?

Thank you. The first question is from Craig Bijou with Bank of America. Your line is open.

Good afternoon. Thanks for taking the questions and congrats on a pretty strong quarter.

Thanks, Craig.

We're discussing the sales representatives and their productivity, particularly regarding your approach to staffing. I believe you're not planning to add many new reps in 2022. Could you provide more insight into your strategy and how you anticipate improving rep productivity this year?

Yeah. Thanks for the question and you're right, we are pretty pleased with our performance in the quarter and for the fiscal year, and we like the sequential revenue growth that we saw in the quarter. We like the fact that Q4 was a record quarter with sequential monthly growth on top of it, and we think that we really did navigate quite well through a very difficult environment. I'm also really pleased that the team was able to hit their targets for the year in terms of number of sales reps, getting to that 150-person dedicated sales force or 30% growth in territories. So, going forward for 2022, we certainly have the opportunity to grow our productivity in terms of our sales team. So they're an important driver of our growth as we're penetrating our core market and expanding our presence in Trauma and Adult Deformity, especially with our second-generation product coming online during the first half of this year. We think that having a dedicated sales team has been a clear differentiator, especially in this unique COVID operating environment and did contribute to 25% procedure growth during the year. But it does help us to enter 2022 with a strong bench that we should be able to leverage over time. And so, we're currently targeting to end 2022 with 170 individuals in the sales force and then more than half of them are going to be quota-bearing territory managers. So, mid-teens increase from that particular perspective. But it really all comes down to gaining that leverage on the existing sales force. We know that a Rep in a territory by himself or herself can do around $1.5 million of business, and then in a territory with the Rep plus a clinical support specialist, they can do on average approximately $2 million of business. So the goal is to continue to add reps, but then start to see that leverage on our sales force as well in 2022.

Great. That's helpful, Laura. Thank you. And I do want to ask about expenses and how to think about expenses going forward. Obviously, there was a bit of an uptick this year, but I know in the past you've made comments about getting back to normal spending levels.

Yeah.

It seems like you could achieve some leverage since you won't be hiring as many salespeople next year, and perhaps some of the R&D investments from the past couple of years will help you gain leverage as well.

That's exactly right, Craig. And the investments that we've made from a sales perspective and an R&D perspective, we believe that 2022 is a year where we can start to gain leverage on those particular investments. So, our primary focus has been on revenue growth and capturing the opportunity that we have in the sacro-pelvic space, but we do also see 2022 as a year where we can gain leverage on that sales force and those R&D investments. And maybe Anshul can add a little bit more in terms of our thoughts there.

Thanks, Laura. Good to talk to you, Craig. Regarding the OpEx growth rate, it is expected to be somewhat lower than the revenue growth rate. As Laura mentioned, we aim to balance ongoing reinvestment in the business with productivity improvements. In terms of spending, we anticipate an increase for several reasons. Firstly, we will be annualizing the costs associated with the new hires from last year; we expanded our sales force and TMs by 30% last year. Additionally, we will continue to invest in R&D, even as we leverage our existing portfolio, with TORQ being a prime example of a differentiated product we've developed. We've actually had a big impact on the market. So we feel good about that. And then we'll also be making some investments to scale our operating infrastructure, Craig, to be able to support the top-line growth that we're looking at over the next few years.

Great. Thanks for taking the questions. I'll hop back in the queue.

Thanks, Craig.

Thanks, Craig.

Thank you. Your next question comes from Kyle Rose with Canaccord. Your line is open.

Hi, everyone, and congratulations on the quarter. I would like to delve a bit deeper into Craig’s earlier question regarding productivity. You've mentioned the $1.5 million and $2 million numbers for several years now. Considering the context, with improved reimbursement and a product portfolio that includes Trauma and Deformity in addition to primary products, I'm trying to understand where the productivity gains from the $1 million range to the $2 million range originate. Could you help us quantify the impact of TORQ in 2021, particularly regarding the competitive gains and the shift towards a greater focus on Trauma in 2022?

Thanks, Kyle. From a productivity standpoint, we see significant potential to increase the average sales per representative in the United States. Since the sales team is crucial for our revenue growth, this may vary regionally based on our decisions. Factors such as the number of surgeons in a territory, the territory size, and the amount of travel required are all considerations. However, we have reached a point where we are sufficiently large and have enough coverage to concentrate more on enhancing sales productivity. We increased the number of senior territory managers by 30% over the past year. Our current objective is to leverage the additional reps we've hired, keeping in mind that it typically takes 12 to 18 months for them to become fully productive. It's important to note that our goal for 2022 is to limit the number of new hires while significantly enhancing productivity. Productivity improvements will stem not only from our senior sales reps but also from the junior clinical support specialists we've recruited, who are more cost-effective. We are already exploring strategies to maximize our channel efficiency, and our plan is to begin realizing these efficiencies in 2022 and moving forward.

Great. Thank you.

You're welcome.

I have one follow-up question regarding the new marketing leader you brought in, who is focusing on direct-to-patient initiatives. I noticed in your prepared comments that you mentioned a doubling in the number of patients targeted. Can you explain how this increase translates into demand and the results you have observed in the field?

There's a couple of key areas that we invested in during the second half of 2021 as it relates to direct-to-patient. The first was just an increase in search spend because we had such a tight amount of search spend that the addition of spending actually showed very similar ROI on those additional dollars as the core dollars that we were spending previously. So our new VP of Digital Marketing really just started with the nuts and bolts of search. Driving patients to our website, having them complete the pain quiz, going through our Find-a-Doctor function and then being ultimately referred to surgeons. And we are able to track all of that information and some of the metrics that we were mentioning are actually directly tied to those items that I just discussed. In addition, in the fourth quarter, the team engaged in more direct-to-patient marketing, focusing on the lower part of the funnel using display advertising, using an educational type of campaign. And what I mean by the lower part of the funnel is those patients who have been in pain management with a chronic SI joint issue for an extended period of time. And so ultimately, these sorts of investments normally take around 12 months for us to actually see the impact from them, but as I said, we've already been making pretty significant investments during the second half of 2021, and so we would expect to see the impact directly turn into case development in the second half of 2022.

Your next question comes from David Rescott with Truist Securities. Your question please.

Hi, Laura. Thanks for taking the questions. First on the expanded reimbursement that you talked about in the prepared remarks. Could you discuss if at all, whether it's anecdotal or more broadly, just where the impact of these factors have started to come out of the business? I mean is this opening up the door for new reps to re-engage with new accounts? Is it reactivating inactive physicians or just more utilization with them, some of the existing accounts? And then, how should we think about that impact throughout the year?

Thank you for the question, David. We are very satisfied with the reimbursement developments we have observed. By the end of 2021, we achieved nearly universal coverage for minimally invasive SI Joint Fusion, and more notably, over 160 million patients now have exclusive coverage for iFuse. This is a significant achievement for us. Regarding the effects of these decisions, particularly with Anthem and United, it's worth noting that Anthem was among the last payors to provide coverage for this procedure. Before August 2021, they did not cover it at all. Their shift to a positive coverage recommendation, which is exclusive to iFuse, represents a major victory for us. And then, a little bit surprising was the decision by UnitedHealthcare to switch from a positive general coverage decision to an exclusive decision. And so, in terms of what we're seeing right now, we're seeing these payors enforce the exclusive policy and while it's early days, we did see an uptick in Anthem case volumes in the fourth quarter that we do attribute to the Anthem decision. We do think that some of these early increases in Anthem cases are likely due to patients who are already in the system for some period of time. Certainly, some patients that had been denied coverage and then that coverage was overturned, it was appealed and there was a positive decision that was made. So that's what we believe that we're seeing here in these early days. But I will say, we are quite excited about the potential tailwind for 2022 from the coverage decisions and the exclusives, especially in the case of Anthem since they were a non-coverage decision. In terms of what we would expect, it normally takes anywhere from six months to 12 months for a new case to work itself through the system before seeing a meaningful impact on volumes, but we have been really focused on the potential impact of these exclusives in our 2022 guidance.

That's helpful. Can you update us on the current status of the backlog that has resulted from the canceled procedures and the cases that carried over from Q4 into January and early February?

It's been an unusual period of time, obviously. We had delta in Q3, and then the start of Omicron in Q4 and then we did talk very openly about what we saw in January and February as well. And so what we've tried to do is to think about this contribution from these procedures over the next few months. And we're encouraged by the fact that we're seeing a decline in the deferrals between January and February. We don't know what March will necessarily look like. And in terms of backlog, the way that our system works is we typically will see the scheduling of cases at the point in time where it's put on the books at a surgeon's office, so it's normally only a few weeks. But we do know anecdotally that there are significant backlogs in the three to four month range, as I had mentioned in my prepared remarks, from talking with some of our surgeons. We also know that historically the way that this has worked, we've gone through so many surges at this point that, what typically happens is you'll have a surge, you'll see a lot of deferrals, then you will see a decline, then a stabilization and then the rescheduling of cases. And so the way that our guidance is looking at this right now is that January was a tough month, February a decline, the stabilization in March, and then starting to see some of this rescheduling in the second quarter.

Okay. That's helpful. Thanks for taking the questions.

Thanks, David.

Thank you. Our next question is from David Saxon with Needham. Your question please.

Hi. Good afternoon, and thanks so much for taking the questions. I guess just one on '22 guidance implies 20% at the high end. But in the past, you've talked about being able to grow well into the 20% range. I think Jeff once said, at 30% plus. So just wanted to hear your view on whether the lower implied growth reflects any change in contents and the opportunity in front of you, or if it's really just a tougher COVID impacted market, with perhaps some conservatism baked in.

Thank you for the question, David. You're pointing us in the right direction. We're very happy with our performance in 2021. We experienced a 25% increase in case volumes despite several surges, which confirms the rising demand for our procedures. Our company is in its strongest position ever, with universal coverage and 160 million patients covered exclusively. We've significantly engaged surgeons, and there has been a 30% increase in the number of territories in the United States served by our sales team, along with a growing range of products. So we feel great about that too. But the operating environment was difficult in January. It's definitely improved in February with fewer deferrals, and we believe that the healthcare environment is still progressing toward becoming fully normalized. When we think about procedure volumes continuing to grow month-over-month, we remain bullish on the underlying business momentum. But given the macro environment, we really think it's prudent to take a more conservative position around the pace of normalization and being deliberate on the impact of the tailwinds, including the exclusives, expansion into Trauma, and our new product launch, all of those things on 2022 revenue growth. But I will reaffirm, we are extremely excited about the year 2022.

The only thing I would add there, David, is you were spot on in the low end of our guidance. As Laura said, it assumes a very conservative scenario with some amount of impact from COVID throughout the year, including continued case deferrals and prolonged backlog of recapture rates. So similar to some of the disruptions we've seen over the last two years, which again if those on the sidelines, we do believe there is tremendous upside in the second half of the year.

Got it. That's super helpful. And then just one on the exclusive policies. I was just wondering if you've seen any benefit with regards to surgeon training. And how are you messaging the exclusive coverage to docs that maybe were reluctant to engage in the past?

Thanks, David. So as for the exclusive policies, at the point in time where the decisions were made by Anthem and UnitedHealthcare, we had a very major marketing campaign that worked with our field sales team in order to reach out to all of the surgeons who were impacted around the country by those decisions. And so, there was a first round of very significant sales and marketing activities around the Anthem decision in the third quarter and then there were more activities that we engaged in, in the fourth quarter with UnitedHealthcare. And you're correct that it did give us the opportunity to re-engage with surgeons that we hadn't engaged with for a while. It allowed us to train some of those surgeons using the Simulator. It makes it very easy to reactivate surgeons who may have been trained previously or those that have expressed interest but never gone through training. And then it also even gave us the opportunity to talk about what's new within the business. So, we went in, and there were some cases where it was appropriate to talk to the surgeons about our new TORQ product. There were cases where it made sense to talk about Bedrock and Adult deformity. What our team was able to do was use the opportunity to speak with those surgeons once again, show them all of our clinical data, show them the five-year data that's driving a lot of these exclusive decisions and then talk to them about ways to engage with us. So it was a major focus point for the sales team along with our field marketing team and gave us a lot of opportunities for engagement in the second half of the year.

Great. Thanks, and congrats on the quarter.

Thanks, David.

Your next question comes from Drew Ranieri with Morgan Stanley. Your question please.

Hi, Laura and Anshul. Thanks for taking the questions. As we consider 2022, could you discuss some of the trends you are observing regarding procedures moving to the ASC setting? Are you seeing or anticipating a greater shift in the current operating environment?

The ASC environment has been a really important site-of-service for us over the last couple of years. As I stated in my prepared remarks, approximately 80% of our procedures are either hospital outpatient procedures or ASC procedures. And before the pandemic, that number was in the single-digit range. We now have gotten in certain months and quarters into the 20% to 25% range for ASC sales. We do see the ASC is a long-term growth opportunity for us just because a lot of procedures are shifting to that site-of-service. It is a cost-effective location for service and it's appealing for quite a few different reasons that also has been absolutely critical to our business over the last two years with the pandemic during surges if hospitals were not able to perform procedures. So I'm not sure how much business we're going to see in the ASC setting, that has yet to be stated.

Got it. Understood. And then just to shift gears to gross margins, but you made some comments about the quarter but I'd like to better understand your guidance for 2022 and some of the pieces there and whether or not kind of the inflationary cost environment is really being a factor in the gross margin guidance.

Hey, Drew. Thanks a lot for that question. We obviously are really proud of our industry-leading gross margins and we came in for 2021 at about 88%. So, when you think about our guidance, both in 2022 and as we think longer term, the way we model it here is we've got a few levers that we look at. One is the ASP decline that we tend to price in on a per procedure basis is not a per implant basis. A lot of that is driven by site-of-service mix, like Laura said, more procedures in ASC, they tend to be a little bit more price sensitive. Especially if you see contribution from TORQ in Adult Deformity, which tend to use fewer implants than the primary SI Joint Fusion. So you've got some of that ASP pressure that we tend to model in, and then we look into two other aspects. The second one being the depreciation expense, especially as we expand our product portfolio, we're expanding the amount of instrument trays that are in the field. That depreciation flows through our gross margin. So that will put some pressure on it. And then when you think about inflation as well, we do model in some amount of inflation, especially this year given everything that's going on, even though our supply chain team has done a phenomenal job in managing through the cost element and actually been very forward-looking in terms of the demand trends and what we need. We do model that in. Now, where do you see long-term gross margin? Sort of that mid to potentially high 80s is where we look at. We're not going to be able to say is at 85%, but our aim is to keep it above that 85 number.

Our next question comes from Dave Turkaly with JMP Securities. Your line is open.

Thank you. I believe you mentioned that the re-engaged surgeons were possibly benefiting from some of the new products. Regarding the 690 active surgeons, could you provide any insights on how many of them were re-engaged versus new customers?

We don't comment on it but it definitely has been a focal area for us to re-engage surgeons. There was a pretty major push in the second half of 2021 to speak with surgeons who had previously been trained and will continue to do that going forward as well. As we said, there were 1,800 surgeons who have trained and treated at least one patient and a thousand of them approximately did at least one procedure in all of 2021. So what that means is, there are approximately 800 surgeons who did not engage with us in that 12-month period, and so those continue to be targets for us.

Got it. Thanks a lot.

Thanks, Dave.

Thank you. This concludes our Q&A session. I will now turn it over to Laura Francis for her final remarks.

Thanks so much, Carmen. I'm pleased with the team's execution in 2021. We hit several record milestones and as we look beyond the near-term impact from the recent resurgence of COVID-19, including the pressure on hospital infrastructure, we see strong underlying momentum in our business. In 2022, we'll continue to leverage our investments to expand the market for sacro-pelvic surgical solutions and drive strong top-line growth. I want to thank you for joining us today and I look forward to meeting you at upcoming investor conferences and events. Goodbye.

And with that, ladies and gentlemen, we thank you for participating in today's program. You may now disconnect. Have a wonderful day.
