摘要:

背景:生物力学的观点认为:强直性脊柱炎的矫形在后凸的顶点处截骨最佳,但术中脊髓损伤的风险大。
目的:分析联合应用椎板间截骨+椎体截骨+长节段椎弓根钉系统内固定治疗强直性脊柱炎后凸畸形的临床效果。
方法:强直性脊柱炎患者共36例,均采用PSO(Pedicle Subtraction Osteotomy)截骨+SPO(Smith-Peterson Osteotomy)联合截骨治疗。随访时间3个月至2年。
结果与结论:36例患者未发现植入物修复后矢状位失平衡者,矢状位失衡的改善率为64%。患者植入物修复后胸腰椎后凸角的到恢复,改善率为60%;颌眉角的改善率为98%,疼痛症状缓解程度为64%,ODI指数95%;均未发生拔钉、断钉、断棒现象。说明选择性截骨矫形技术+长节段内固定手术能够获得稳定的内固定疗效,防止出现矢状位失平衡,以及强直性脊柱炎因骨质疏松导致的拔钉、断钉、断棒现象的发生。

Abstract:

BACKGROUND: Orthopedic osteotomy at the apex of kyphosis is best for treatment of ankylosing spondylitis from a biomechanical aspect, but there is a high risk for intraoperative spinal cord injury.
OBJECTIVE: To explore the clinical efficacy of vertebral plate osteotomy + vertebra osteotomy +long-segment pedicle screw fixation in the treatment of ankylosing spondylitis with kyphotic deformity.
METHODS: Thirty-six patients with ankylosing spondylitis were subjected to pedicle subtraction osteotomy and Smith-Peterson osteotomy, and then followed up for 3 months to 2 years.
RESULTS AND CONCLUSION: After implantation, sagittal imbalance did not occur in 36 patients, and the improvement rate of sagittal imbalance was 64%. The improvement rates of thoracolumbar kyphosis and chin-brow vertical angle were 60% and 98%, respectively. The pain relief rate was 64%, and the Oswestry Disability Index was 95%. There were no pulled nails, broken nails and broken robs after implantation. These findings indicate that the combination of selective osteotomy technique and long-segment internal fixation can achieve stable fixation effects, prevent sagittal imbalance, and avoid the occurrence of pulling nails, breaking nails and breaking robs caused by osteoporosis.
