Thank you, Matt, and good morning to everyone listening. Xtant Medical withstood significant market challenges in 2021 to grow our annual revenue for the first time in six years, and for the first time since Bacterin acquired X-spine to form Xtant Medical. In 2021, we grew our overall business by 4%, led by our established biologics business, which grew by 8%. Our commercial team delivered to bring hospitals and physicians our innovative products so that patients receive the treatment they so desperately need. On today's call, I will first address our current market conditions and our performance in the fourth quarter and full-year, then provide an update on the progress of our growth strategy, and close with commentary on our operations. Okay, first, starting with the market environment. On a macro level, 2021 was an up-and-down year. In Q1, we got hit with the last wave of the COVID Alpha variant, in Q2 we swung back to mostly normal caseloads. And then in the third and fourth quarter we got hit with the Delta variant, followed by the Omicron variant, like everyone else did, while not as challenging as 2020, overall spine procedures by our internal metrics were still down by at least 10% compared to 2019. COVID restrictions had a profound impact on our business with spine and other surgery procedure volumes negatively impact in many of our key markets. This was due to cancellations and/or postponements of procedures as a result of increased hospitalizations, restrictions on elective procedures, and staffing shortages. Despite these headwinds, we achieved top line growth in 2021 primarily driven by our key growth initiatives, and have helped to diversify our revenue stream. Although the reduction in elective procedures and staffing issues continue to linger early in the first quarter of 2022, we are cautiously optimistic that conditions will improve as COVID cases continue their decline, and restrictions are once again loosened. I'd like to now touch on the four key growth initiatives and the progress made in 2021. As a reminder, these pillars of growth are focused on, one, a regular cadence of new products, two, expansion of our distribution network, three, penetration of adjacent markets, and four, leveraging our growth platform with technology and strategic acquisitions. All right, starting with our new product introductions. During 2021, we launched four new products, including most recently, a bone marrow aspirate concentrate offering, which was introduced in November of 2021. Reception to our new products has been quite positive, particularly with the successful launches of our OsteoFactor and OsteoVive Plus products. Not only do they add to our broad biologics portfolio, but they also enable us to enter the $670 million gross growth factor market. We intend to rollout two new products this year, and as many as four new products, annually, in the years ahead, with a focus on products that expand our reach into new markets and revive and update existing successful products. Altogether, we are driving new innovations in the biologics sector, and bringing differentiated products to market. The second growth pillar is the expansion of our distribution network. This initiative is critical to advancing sales coverage into new U.S. geographies. I am pleased that, in 2021, we brought in more than 47 new agents, which exceeded our previously stated goal of adding 10 agents per quarter. We grew in the Midwest, New England, California, Arizona, in the Southeast, and especially in the Mid-Atlantic. Still, we see further room for expansion in 2022 as we remain committed to having more regions represented by more distributors. Our third pillar of growth is focused on penetrating adjacent markets. In 2021, we added new sales personnel to leverage certain adjacent non-spine markets, such as the foot and ankle, cranial/maxillofacial, oncology, joint reconstruction, and trauma markets. By expanding our private label and OEM sales into these markets, we made considerable progress on this initiative in 2021. While COVID had a severe impact on spinal elective procedures, many procedures in these adjacent markets continue to move forward, allowing us to benefit from diversifying our revenue streams. Finally, one of our key growth initiatives is to add depth to our product offering through targeted strategic acquisitions. This is a strategy that takes time and prudence to execute. We continue to explore opportunities that align with our growth platform, provide scale, fill product or technology gaps, expand into adjacent markets or broaden our access to customers with the goal to increase long-term shareholder value. Now, moving to our operational performance, I'd like to remind everyone of the strategic and intentional decisions made by the management team to temporarily lower our gross margins. Part of the strategic margin decline was related to product mix due to higher OEM channel sales, which actually has a slightly better operating margin than our independent agent sales channels. The more intentional and temporary margin decline was due to our efforts to lower our finished goods inventory. As a result, we reduced our finished goods inventory by more than $4 million, however, it also temporarily increased our under-absorption of labor and overhead. We expect higher production costs to continue in future periods, but otherwise expect gross profit to improve as the effect of COVID-19 on surgical procedures diminishes. With anticipated higher volumes later in the year, we expect to see our absorption number go much lower. Lastly, we set a solid foundation in 2021 for future growth by laying the groundwork across each of our four key growth initiatives. We've brought exciting new products to market that have already contributed to our top line, we grew our distribution network above our expectations, and benefited from the continuation of certain procedures by expanding in adjacent markets. Supported by our growth platform and operating from a position of financial strength, we look forward to a very promising 2022 for our business and shareholders. Now, I would like to introduce Scott Neils, who was appointed interim CFO at the start of this year. Scott has 15 years of public accounting and corporate finance experience, serving as our control since August 2019. We are excited to have Scott here with us today to discuss our fourth quarter and full-year 2021 financial results.
