Pedicle subtraction osteotomy is one of the well established and popular techniques for kyphosis correction. 52 patients with dorsolumbar kyphosis followed up for a minimum period of 2 years after pedicle subtraction osteotomy were assessed prospectively for clinico-radiological and functional outcomes. Unacceptable cosmesis and severe back pain were the chief complaints preoperatively.
The average kyphosis at last follow-up was 8.4° compared to preoperative kyphosis of 58°. Union at the osteotomy site was achieved in all patients, and there were no major neurological complications. All patients showed a significant improvement in all subsets of Scoliosis Research Society (SRS-30) outcome measures following the surgery.
A greater degree of kyphosis correction (>40°) can be obtained with a single pedicle subtraction osteotomy at the dorsolumbar level with minimal neurological complications.
脊柱截骨术是一种成熟且流行的脊柱后凸矫正技术。52 例胸腰椎后凸患者行脊柱截骨术后至少随访 2 年，前瞻性评估其临床、放射学和功能结果。术前主要抱怨是美容效果不佳和严重背痛。
末次随访时平均后凸角度为 8.4°，术前为 58°。所有患者均在截骨部位愈合，无严重神经并发症。所有患者术后脊柱侧凸研究协会（SRS-30）各项评分均显著改善。
在胸腰椎水平行单一脊柱截骨术可获得更大程度的后凸矫正（>40°），且神经并发症最小。
