Impact of Specialty on Cases Performed During Spine Surgery Training in the United States.

Objective: Two general pathways exist for spine surgery training in the United States: orthopedic surgery and neurological surgery. Previous studies have not quantified the impact of fellowship training when comparing case volumes between these 2 training pathways. This study compares reported spine surgery case volume upon graduation from orthopedic surgery and neurological surgery training.
Methods: This was a retrospective cohort study of recent graduates from orthopedic surgery and neurological Surgery training programs in the United States (2018-2021). The Accreditation Council for Graduate Medical Education provided case logs for residents in neurological surgery and orthopedic surgery as well as fellows in orthopedic spine surgery. Case volumes were compared for adult and pediatric spine surgery cases using parametric tests.
Results: Case logs from 3146 orthopedic surgery residents, 107 orthopedic spine surgery fellows, and 766 neurological surgery residents were included in this study. Across each cohort, neurological surgery trainees reported more total adult spine surgery cases than orthopedic surgery trainees (514 ± 206 vs. 383 ± 171, P < 0.001). Orthopedic surgery trainees reported more total pediatric spine surgery cases (21 ± 14 vs. 17 ± 12, P = 0.006).
Conclusions: Neurological surgery training affords a greater volume of adult spine surgery cases, but orthopedic surgery affords more pediatric spine surgery cases. Identification of relative strengths and weaknesses can help facilitate multidisciplinary training experiences in spine surgery.
