摘要
目的:观察经后路Ⅰ期椎间颗粒骨打压植骨融合术治疗胸腰椎爆裂骨折伴脱位临床疗效。方法:对采用后路减压国产通用型脊柱固定系统(GSS)椎弓根螺钉固定联合椎间植骨融合手术治疗的12例胸腰椎爆裂骨折脱位患者进行了随访,比较术前、术后相邻椎体上下终板成角(Cobb角)、椎体前缘高度与正常高度的比值、椎管骨性占位率等指标,了解术后骨折复位情况及随访期间内固定有无失败和复位丢失情况。结果:通过手术减压复位,Cobb角、椎体前缘高度与正常高度的比值、椎管骨性占位率均明显改善。术后随访测量与术后相比无明显变化,无1例内固定失败。结论:后路椎弓根螺钉联合椎间植骨治疗胸腰椎爆裂骨折伴脱位可以有效防止内固定失败、复位丢失和后凸畸形,是治疗胸腰椎骨折伴脱位较理想方法。
Objective ： To investigate of the clinical efficacy I stage posterior particle bone grafting of the intervertebral fusion in treat- ment of thoraeolumbar burst fracture with dislocation. Methods：The study involved 12 patients with thoracolumbar burst fractures with dis- location treated with posterior pedicle screw instrumentation plus interspinal bone grafting. The Cobb angle, the ratio of anterior body height to the normal height and spinal canal blockage before and after surgery were compared for observation on postoperative fracture healing as well as internal fixation failure or reduction loss during follow-up. Results：The operative decompression and reduction exerted significantly positive effect on the Cobb angle, the ratio of anterior body height to the normal height and spinal canal blockage. The follow-up showed no significant correction loss or fixation failure. Conclusion：Posterior pedicle screw plus interspinal bone grafting is an ideal method for treat- ment of thoracolumbar burst fractures with dislocation,it can prevent failure, reduction loss and kyphofic deformity.
