Incidence and Complications of Open Hip Preservation Surgery: An ABOS Database Review

Hip preservation surgery encompasses various surgical procedures that have the goal of decreasing the progression of osteoarthritis, preserving normal hip function, and delaying the need for arthroplasty. These procedures can encompass arthroscopic, open, and combined techniques. This study investigated the trends and complications associated with open hip preservation surgery performed by candidates undergoing Part II of the American Board of Orthopaedic Surgery examination. The American Board of Orthopaedic Surgery Part II surgeon case database was queried from the years 2003 to 2013 for Current Procedural Terminology (CPT) codes related to open hip preservation surgery in patients 10 years and older. Patient demographics, fellowship training, geographic location, and complications were extracted from the database. These data were analyzed to determine the incidence by year of individual procedures and complications. During the study period, 644 cases (352 male, 292 female; mean age, 29.7 years) and 730 CPT codes were reported. The most commonly reported fellowship was pediatric orthopedics. No trend was observed in the overall incidence of these surgeries, but there was an increase in the number of cases performed in the Midwest. There were 212 reported complications, with a rate of 33% per case, or 29% per CPT code (range, 12.5%-100% per CPT code). Complications reported ranged from infection to death. The incidence of complications over time showed no discernible trend. Based on the results of this study, the yearly incidence and complications associated with open hip preservation surgery performed by surgeons undergoing board certification should continue at a predictable rate.
