Abstract：Objective To evaluate the efficacy and safety of spinal posterior wedge osteotomy for correction of severe rigid idiopathic scoliosis.Methods Seventeen consecutive cases with severe rigid idiopathic scoliosis were treated by spinal posterior wedge osteotomy. There were 5 males and 12 females, and the average age was 18.6 years(14-24 years). The Lenke classification involved 3 cases in Lenke Ⅱ, 4 cases in Lenke Ⅲ, 4 cases in Lenke Ⅳ, 6 cases in Lenke Ⅵ. The coronal and sagittal Cobb′s angles, sagittal trunk shifts, and fusion segments were measured on standing AP and lateral radiographs before, after surgery and the final follow-up.Results The average follow-up was 47.6 months(12-84 months). The Cobb′s angle in the coronal plane was corrected from 102.2° to 39.4°, the correction rate was 61.4%. The Cobb′s angle in the sagittal plane was corrected from 49.5° to 8.6°, the correction rate was 82.6%. Coronal trunk shift was obviously improved from -29.8 mm to -3.5 mm. The average fusion segments were 14, ranging from 11 to 16. Perioperative complications consisted of pleura injury in 4 cases, and gastrointestinal dysfunction in 2 cases.Conclusions Spinal wedge osteotomy correction by the single posterior approach is a reliable and safe surgical technique for correction of severe rigid idiopathic scoliosis.
