Variations in surgical practice and short-term outcomes for degenerative lumbar scoliosis and spondylolisthesis: do surgeon training and experience matter?
i) Study design: Observational study
ii) Fellowship-trained surgeons had lower readmission rates.
iii) Surgeons with higher operative volumes used instrumented fusion more often (OR = 1.1, 95% CI 1.0-1.2, P < .05 for both diagnoses) and had lower rates of major in-hospital complications (OR = 0.91, 95% CI 0.85-0.97; P = .006)
iv) Residency and fellowship training present important opportunities to optimize surgical practice over the course of surgeons' careers
