Preliminary results for ConforMIS, Orthofix and OrthoPediatrics were mixed. While ConforMI's net revenue for the year grew in the double digits, adjusting for product-only revenue reveals a mostly flat year. Orthofix rode strong spinal implant sales to mid-single-digit growth for the year but was impacted by the slowdown in the biologics market. OrthoPediatrics continued to leverage its leadership position in the pediatric space to achieve aggressive sales growth for both the quarter and year.
As noted in Part I of our quarterly revenue coverage, robotics and enabling technology in general continued to be a major theme supporting growth for publicly-traded companies.
In November, we published our downloadable report, 2018 Revenue Projections: Companies Over $200 Million, for the 25 largest orthopaedic companies. Sales for these 25 companies account for ~80% of the worldwide orthopaedic market. We project that these companies will combine for $41 billion in 2018 revenue, +3% vs. 2017.
