经椎弓根椎体截骨Gss内固定术对脊柱后凸畸形的治疗体会

Application of transpedicular vertebral osteotomy and Gss internal fixation in correction of kyphosis deformity

目的：探讨脊柱后凸畸形的手术方法和治疗体会。方法：应用经椎弓根椎体截骨Gss内固定术治疗脊柱后凸畸形共33例。结果：随访6—28个月，术前Cobb角37°-83°，平均57°，术后Cobb角平均12．5°，平均矫正44．5°，矫正率78．1％。结论：经椎弓根椎体截骨结合Gss内固定术是治疗脊柱后凸畸形满意和可靠的方法。

Objective：To discuss the operative technique and therapeutic experience in corrction of kyphosis deformity. Methods：There had been 33 cases of kyphosis deformity accepted the treatment of transpedicular vertebral osteotomy and Gss internal fixation. Results： All cases were followed - up 6 to 28 monthes, the Cobb angle was 37°to 83° before operation with average Cobb angle 57°, after operation the average Cobb angle was 12.5°. The average correction was 44.5° and the correcting rate was 78.1%. Conclusion：Application of transpedicular vertebral osteotomy and Gss internal fixation in correction of kyphosis deformity might be a liable and safe sura＇ical techniaue.
