摘要
目的 探讨经皮脊柱内窥镜治疗腰椎间盘突出症合并椎体后缘离断的可行性及近期疗效。方法 2008年7月-2013年1月,采用经皮脊柱内窥镜治疗腰椎间盘突出症合并椎体后缘离断57例。男39例,女18例;年龄13～46岁,平均26.7岁。29例有明确腰部外伤史。均为单节段单侧椎间盘突出,其中L4、522例,L5、S135例。离断骨块为侧方型25例,中央型32例;位于L4椎体后下缘9例,L5椎体后上缘13例,L5椎体后下缘8例,S1椎体后上缘27例。均采用症状侧单侧入路（椎板间或椎间孔入路）,镜下摘除突出椎间盘、部分或完全切除离断的骨块。结果 术中均准确定位,无神经根损伤、血肿形成及硬膜囊撕裂等并发症发生。手术时间20～85 min,术中透视次数2～15次,术中出血量3～10 mL。术后影像学检查示离断骨块未切除16例,部分切除32例,完全切除9例;椎间盘均彻底摘除。患者均获随访,随访时间10～64个月,中位时间16个月。术后6个月根据Macnab术后疗效评定标准,获优48例,良6例,可3例,优良率94.7%。结论 经症状侧单侧入路经皮脊柱内窥镜治疗腰椎间盘突出症合并椎体后缘离断,具有损伤小、对腰椎正常结构破坏小、出血量少、康复时间短等优势,近期疗效较好,远期疗效有待进一步观察明确。
Objective To investigate the feasibility and short-term effectiveness of percutaneous endoscopic spine surgery for treatment of lumbar disc herniation with posterior ring apophysis separation. Methods Between July 2008 and January 2013, 57 patients with lumbar disc herniation and posterior ring apophysis separation were treated. There were 39 males and 18 females, aged from 13 to 46 years （mean, 26.7 years）. Of 57 cases, 29 had a clear trauma history. All patients had single segmental unilateral lumbar disc herniation, and the location was at L4, 5 in 22 cases and at L5, S1 in 35 cases; there were 25 cases of lateral bone fragments and 32 cases of central cortical and cancellous fragments. While fracture located at posterior inferior edge of the vertebrae at L4 level in 9 cases and at L5 level in 8 cases, at posterior superior edge at L5 level in 13 cases and in S1 level in 27 cases. Percutaneous endoscopic surgeries were performed via interlaminar or transforaminal approach from unilaterally symptomatic side for discectomy of lumbar disc herniation and partial or complete resection of free bone fragments. Results Accurate positioning was obtained in all patients during operation, and no complication of nerve root injury, hematoma formation, or dural tear occurred. The operation time was 20-85 minutes; the intraoperative fluoroscopy times were 2-15 times, and the blood loss was 3-10 mL. Postoperative radiographic examination showed that bone fragment was not removed in 16 cases, was partly removed in 32 cases, and was completely removed in 9 cases. Disc was completely removed. All patients were followed up 10-64 months （median, 16 months）. According to modified Macnab criteria for the evaluation of effectiveness, the results were excellent in 48 cases, good in 6 cases, and fair in 3 cases, and the excellent and good rate was 94.7%. Conclusion Percutaneous endoscopic spine surgery through unilaterally symptomatic approach has advantages of small tissue damage and lumbar structure damage, less bleeding, and
