摘要
目的 探讨半椎体畸形切除手术入路及内固定方式的选择。方法 12例半椎体畸形患者,采用后路半椎体切除中华长城椎弓根系统椎弓根固定5例,侧前方入路胸腹膜外半椎体切除中华长城系统椎体固定7例;均行椎体间植骨。术后3周带支具下地活动。结果 随访时间3-24个月,矫形满意,未出现脊髓损伤,1例术中胸膜破裂行修补术。Cobb角术前平均38°(20°-55°),术后平均10°(5°-15°),矫正率达73.7%。无一例出现内固定松动断裂。结论 半椎体畸形的矫形,后方和侧前方入路切除半椎体均能达到较好治疗效果,侧前方入路创伤小,视野开阔。中华长城器械应用于半椎体畸形矫形,操作简单,矫正效果好。
Objective To explore the surgical approaches of resection of hemivertebra and style of internal fixation. Methods 12 affected children with hemivertebra deformity were retrospectively reviewed and analyzed. 5 cases were operated by resection of hemivertebra through posterior approach, and were fixed by China Great Wall pedicle screw system. 7 cases were operated by resection of hemivertebra through anterolateral approach and were laterally fixed by China Great Wall pedicle screw system in vertebra. All cases were performed with intervertebral bone autograft. Out of bed activities were allowed in 3 weeks postoperatively. Results All cases were followed up for 3 - 24 months. The operation was satisfied. The average preoperative curves measured 38° (ranging 20°- 55°). Immediate postoperative curves averaged 10°( ranging 5°- 15°). According to the analysis of clinical records, the amount of curve correction in coronal plane averaged 73.7%. There was no infection ,spinal cord injury and fracture of interal fixation. Conclusions Both of posterior and anterolatcral approachs can permit complete resection of hemivertebra and have good clinical effect. China Great Wall pedicle screw system can provide satisfactory correction with less fusion segments.
