Case Volume Benchmarks During Residency and Fellowship Training for Pediatric Orthopedic Surgeons.

Higher case volumes correlate with improved clinical outcomes across surgical specialties. This study establishes case volume benchmarks after completion of pediatric orthopedic fellowship training. Case logs for orthopedic surgery residents and pediatric orthopedic fellows at accredited programs were analyzed (2017-2018 to 2020-2021). Case volumes for pediatric orthopedic surgery were compared using parametric tests. Case logs from 3,000 orthopedic surgery residents and 149 pediatric orthopedic fellows were analyzed. There was an increase in total pediatric cases among orthopedic surgery residents over the study period (273 ± 68 to 285 ± 76, 1.1% annual increase, P<0.001). On average, pediatric orthopedic fellows reported 276 cases: Spine deformity (55 cases, 20%), foot and ankle deformity (45 cases, 16%), hip reconstruction (34 cases, 12%), limb deformity (32 cases, 12%), trauma lower limb (24 cases, 9%), treatment of supracondylar humerus fracture (23 cases, 8%), trauma upper limb (19 cases, 7%), clubfoot (18 cases, 7%), soft tissue procedures (13 cases, 5%), open treatment of femoral shaft fractures (6 cases, 2%), and treatment of infection (7 cases, 3%). Pediatric orthopedic fellows effectively doubled their pediatric case volume from fellowship training. The distribution of pediatric orthopedic fellow case volume percentiles was: 10 - 191 cases; 30 - 237 cases; 50 - 275 cases; 70 - 318 cases; 90 - 382 cases. Case volume benchmarks can help inform orthopedic trainees, faculty, and patients about the impact of pediatric orthopedic fellowship training. More research is needed to elucidate optimal training environments for future pediatric orthopedic surgeons.
