Sacral-Alar-Iliac Fixation in Pediatric Deformity: Radiographic Outcomes and Complications

Research output: Contribution to journalArticlepeer-review

Abstract

Study Design Retrospective case series. Objectives To assess the radiographic outcomes and complications of sacral-alar-iliac (SAI) fixation in children. Summary of Background Data Pelvic fixation in children undergoing spinal deformity surgery can be challenging because of complex anatomy, compound biomechanical forces at the lumbosacral junction, and poor bone quality. Methods Radiographic and clinical records of 80 consecutive patients aged 18 years or younger who underwent posterior spinal fusion surgery with SAI fixation by one pediatric orthopedic surgeon and who had a minimum 2 years of follow-up (mean follow-up: 3.5 years, range, 2-7 years) were retrospectively reviewed. Changes in coronal curve magnitude and pelvic obliquity were assessed using Student t tests. Significance was set at a p value less than.05 for all analyses. Results Pelvic obliquity correction averaged 77%, from 26 ± 13 degrees before surgery to 6 ± 4 degrees at final follow-up (p 8 mm. Level of Evidence Level 4.
