摘要
目的 :探讨椎弓根螺钉内固定在矫治脊柱后凸中的应用及截骨方法的选择。方法 :本组 2 5例全部采用单节段截骨。椎板、小关节截骨 8例 ;三柱楔形截骨 17例。全部采用短节段的椎弓根内固定装置 ,其中RF 12例 ,CD 3例 ,STB 10例。结果 :本组 2 1例得到 3、6、12个月的随访 ,其腰背痛消失或大部分缓解 ,截骨部位获得骨性愈合 ,后凸角度由手术前平均 70° ,矫正到平均 33° ,矫正角度丢失平均 2 .5° ,矫正率为 5 2 .9%。内固定装置无松脱和断裂。结论 :用椎弓根螺钉内固定矫治脊柱后凸牢固可靠 ,对于年龄小、无腹腔血管钙化、后凸 <6 0°可选用椎板、小关节截骨 。
Objective: To evaluate the outcome of correction of lumbar kyphotic deformity by transpedicle instrument and to choose the methods of osteotomy.Methods:25 cases of ankylosing spondylitis with kyphotic deformity were corrected by single level osteotomy with transpedicle fixation,using RF 12,CD 13,STB 10,including 8 cases by laminectomy and facet joints excised and 17 cases by vertebral body wedge osteotomy.The mean preoperative kyphotic deformity was 70°,Results:21 cases were followed up within 3,6,12 months.The mean postoperative kyphosis was 33°.Mean loss of correction was 2.5°.Corrective rate was 52.9%.Low back pain relief and excellent bone healing was achieved in 21 cases.No loosing and breaking of instruments were found in all cases.Conclusions:Transpedicle fixation of lumbar kyphotic deformity correction was stable.Less 60° of lumbar kyphotic deformity was corrected by laminectomy and facet joint excised in youngs without aortic calcification,otherwise,by vertebral body wedge osteotomy.
