Increasing Value in Subspecialty Training: A Comparison of Variation in Surgical Complications for Pediatric Versus Other Fellowship-trained American Board of Orthopaedic Surgery Candidates in the Treatment of Supracondylar Fractures.

Introduction: The effect of orthopaedic fellowship subspecialization on surgical complications for patients with supracondylar fracture is unknown. This study seeks to compare the effect of subspecialty training on supracondylar fracture complications.

Methods: The American Board of Orthopaedic Surgery Part II Examination Case List database was reviewed for all supracondylar fractures from 1999 to 2016. Procedures were divided by fellowship subspecialty (trauma, pediatric, or other) and case volume and assessed by surgeon-reported surgical complications. Predictive factors of complications were analyzed using a binary multivariate logistic regression.

Results: Of 10,961 supracondylar fractures identified, 53.47% were done by pediatric fellowship-trained surgeons. Pediatric-trained surgeons had fewer surgical complications compared with their trauma or other trained peers (4.54%, 5.67%, and 6.24%; P = 0.001). Treatment by pediatric-trained surgeons reduced surgical complications (OR = 0.79, 95% CI: 0.66 to 0.94; P = 0.010), whereas increased case volume (31+ cases) showed no significant effect (OR = 0.79, 95% CI: 0.62 to 1.02; P = 0.068). Patient sex, age, and year of procedure did not affect complication rates, while those treated in the Southeast region of the United States and those with a complex fracture type were at increased odds.

Discussion: Treatment of supracondylar fractures by pediatric-trained surgeons demonstrates reduced surgeon-reported complications compared with their other fellowship-trained counterparts, whereas case volume does not. This suggests the value of fellowship training beyond pertinent surgical caseload among pediatric-trained surgeons and may lie in targeted education efforts.
