Key Points

To compare the direct costs of anterior and posterior spinal instrumented fusion for adolescent idiopathic scoliosis.
Cost analysis of anterior spinal instrumented fusion (ASIF) and posterior spinal instrumented fusion (PSIF)
Comparison of postoperative ICU admissions and hospital length of stay (LOS)
Exclusion of outliers to evaluate average costs effectively.
ASIF had significantly higher direct costs due to increased ICU admissions and longer LOS.
Excluding outliers showed similar average direct costs between ASIF and PSIF.
ASIF resulted in one fewer treated level on average.

Implication

Cost comparison reveals similar expenses for spine surgery techniques in adolescents with scoliosis, suggesting efficiency.
