Background and Aims: Posterolateral hemivertebrectomy with monosegmental instrumentation at an early age is an established method to correct congenital scoliosis but is associated with a relatively high risk of instrumentation failure and health-related quality of life outcomes are not available. We aimed to investigate the effects hemivertebrectomy with postoperative hip spica cast on complications and health-related quality of life in small children with congenital scoliosis. Materials and Methods: A follow-up study of 30 children (at mean age = 3.4 years, range = 1.0-8.5 years) undergoing posterolateral hemivertebrectomy and short pedicle instrumentation. Children were immobilized postoperative with hip spica cast for 6 weeks and immobilization for 4 months using a rigid thoracolumbosacral orthosis. The Caregivers filled out Scoliosis Research Society 24 outcome questionnaire preoperatively, at 6 months, and at final follow-up visit on behalf of their child. Standing radiographs were obtained preoperatively, postoperatively in the cast, and standing at final follow-up. Results: Mean major curve was 41 degrees (range = 26 degrees-87 degrees) preoperatively and was corrected to 14 degrees (4.0 degrees-35 degrees) at final follow-up. Eight (27%) children had postoperative complications, including three (10%) deep surgical site infections. The Scoliosis Research Society 24 back domain showed an improvement from a mean of 3.8 preoperatively to 4.4 at final follow-up (p < 0.001). Function from back condition domain showed a significant deterioration from 4.2 preoperatively to 3.7 at 6 months (p = 0.020) but improved back to baseline at final follow-up (4.2, p = 0.0022 6 months vs final follow-up). Conclusion: Hemivertebrectomy with short instrumentation resulted into 64% correction of scoliosis and improved health-related quality of life in back pain and function domains.
