摘要
目的探讨后路经皮肌间隙入路在胸腰椎骨折中短节段椎弓根钉固定应用的临床疗效。方法自2009-07—2011-07应用后路经皮双侧共4个棘旁小切口,经肌间隙入路,切开复位、短节段椎弓根钉内固定治疗胸腰椎骨折30例。结果本组手术顺利,手术时间40~60 min,平均50 min;手术出血量40~150 ml,平均60 ml。术后X线侧位片测量手术椎椎体前缘的压缩百分比由术前（43.0±5.1）%减小至（8.6±2.3）%,差异有统计学意义（P〈0.05）;术后骨折椎体后凸Cobb角由术前（26.2±3.1）°缩小至（6.2±1.3）°,差异有统计学意义（P〈0.05）。末次随访时未见明显椎体高度和后凸畸形矫正丢失。结论采用后路经皮肌间隙入路短节段椎弓根钉固定治疗胸腰椎骨折固定可靠、操作简单、创伤小,易于推广。
Objective To analyze the results of posterior percutaneous approach short-segmental pedicle screw internal fixation in treatment thoracolumbar vertebral fractures. Methods From Jun. 2009 to Jun. 2011, 30 cases of thoracolumbar vertebral fractures were operated. All cases were treated by posterior percutaneous approach short-segmental pedicle screw internal fixation. The place of pedicle screw and reduction of fracture vertebral body were observed. Results All cases had no any neurovascular complications and failure of internal fixation. Bone fusion of fractures reached after 3 months. There were restoration of anterior body compression from mean preoperative（43.0±5.1）% to postoperative（8.6±2.3）%（P 0.05）, and restoration of Cobb angle from mean preoperative（26.2 ±3.1）° to postoperative（6.2 ±1.3）°（P 0.05）. At the last follow-up, there were no obvious vertebral height and kyphosis correction loss. Conclusion Using posterior percutaneous approach by short-segmental pedicle screw internal fixation in treatment thoracolumbar vertebral fractures is a feasible technique and deserves wider use.
