目的评价经后路胸膜外松解胸椎间隙联合顶椎区楔形截骨结合椎弓根螺钉内固定矫正术治疗重度僵硬性脊柱侧后凸畸形的安全性和早期临床效果.方法 2004年3月至2007年6月,对14例重度僵硬性脊柱侧后凸患者行手术治疗.男6例,女8例;年龄15-31岁,平均22.1岁.其巾特发性7例,先天性6例,神经纤维瘤病l例.术前侧凸Cobb角81°～139°,平均111.2°;后凸57°～165°,平均85.8°.所有患者均行一期经后路胸膜外松解椎间隙联合顶椎区楔形截骨,经椎弓根螺钉内固定矫止及植骨融合术.结果平均松解椎间隙5.1个,椎体截骨平均2.3个,手术时问7.2～14.1 h,平均9.2 h.术中出血量1500～6100 ml,平均3970 ml.无神经损伤,2例术中胸膜破裂,1例术后并发肠系膜上动脉综合征.所有患者经过7～31个月随访,平均12.7个月,术后侧凸Cobb角15°～71°,平均31.3°,矫正率71.9%;后凸22°～48°,平均34.9°,矫正率59.3%.结论经后路胸膜外松解胸椎间隙节省了前路经胸的于术时间,创伤小,对心肺干扰小,降低了风险,改善了脊柱柔韧性.顶椎区凸侧三柱楔形截骨,依靠凹侧保留的椎间纤维环、黄韧带及肋椎关节作为稳定铰链,手术较伞脊椎切除术简便、安全.对重度僵硬性弧形脊柱侧后凸用单一的截骨术难以达到三维矫正,后路椎间隙松解联合顶椎区楔形截骨结合椎弓根螺钉内崮定矫正能获得良好的脊柱三维矫正.

Objective To evaluate the early result of the efficacy and safety of posterior thoracic intervertcbral space release and wedge osteotomy for severe and rigid kyphoscoliosis.Methods From 2004 to 2007,twelve patients with severe and rigid kyphoscaliosis were treated with posterior thoracic intervertebral space release and wedge osteotomy on the apex vertebra.Trans-pedicular screws fixation and fusion were used aftcr deformity correction.There were 6 males and 8 fmales with an average age of 22.1 years (15-31 years old).The average pre-operative scoliosis cobb,angle was 111.2°(81°-139)° and kyphosis cobt)angle was 85.8°(57°-165°)be|bre operation.Results All patients were followed up for 7-3l months (months averagely).An average of 5.1 thoracic vertebra were released and 2.3 vertebra were wedge resected.The average surgery time was 9.2 hours and average bh,o,t loss vo]umn of 3970 ml(1500-6100 mL).There were no major complication of neurological injury and hardware failure.There were 2 cases pleura rupture during the operation and 1 cases of superior mesenterie artery syndrome after the surgery.The postoperative average scoliosis and kyphotic curve was 31.3°(15°-71°)and 34.9°(22°-48°),respectively.The correction rate for scoliosis and kyphotic was 7 1.9%and 59.3%.respectively.Conclusion Costotransversectomy release of thoracic vertebra via single posterior approach Carl avoid open cbest surgery and reduce the disturbance of heart and lung.The wedge osteotomy of the vertebral column at the apex of the deformity based on the preserved annulus fibrosus and ligment flavum and costovertebral ioints in spinal concave side can keep the segmental stability and increase the surgery safety.Posterior thoracic intervertebral space release and wedge osteotomy is proved to be an effective and safe way for severe and rigid kyphoscoliosis.
