Objective: To understand trends and variability of procedures performed by orthopedic spine surgery fellows during training.
Design: Cross-sectional survey.
Setting: Accreditation Council on Graduate Medical Education (ACGME) case logs.
Participants: Fellows enrolled in ACGME-accredited "Orthopaedic Surgery of the Spine" fellowships from 2010 to 2015.
Results: The 2010 to 2015 ACGME fellowship case logs for "Orthopaedic Surgery of the Spine" were retrieved. Spine cases in case logs are grouped into the following categories: (1) Excision, (2) Osteotomy, (3) Fracture and/or Dislocation, (4) Decompression, (5) Anterior fusion/arthrodesis, (6) Posterior fusion, (7) Deformity surgery, (8) Exploration, (9) Instrumentation, and (10) other/uncategorized. The total number of spine cases logged by each fellow increased from 821 in 2010 to 1134 in 2015 (38.2% increase). The greatest increases were noted from fracture/dislocation cases (77.9%), followed by posterior fusions (62.2%), anterior fusions (43.6%), decompressions (36.3%), and instrumentation (29.5%). The average number of deformity cases decreased from 23 in 2010 to 19 in 2016 (18.6% decrease). The average number of adult-only cases increased from 770 in 2010 to 1100 in 2015 (42.8% increase), whereas the average number of pediatric-only cases declined from 51 in 2010 to 35 in 2015 (32.1% decrease). Based on case logs from 2015, the greatest variation in case volume between the 10th centile and 90th centile of fellows was noted for deformity cases, followed by decompressions and posterior fusions.
Conclusions: Even though there has been a 38% increase in the overall number of spine cases performed by fellows during training, a large amount of variation in type of case exposure exists between fellowships. The findings of our study call for the establishment of minimal case volumes and/or uniformity of training spectrums across the nation to ensure appropriate surgical care is made accessible to all patients.
