椎管减压结合病椎骨水泥注射治疗脊柱转移癌临床观察

目的 观察椎管减压结合病椎骨水泥注射治疗脊柱转移癌的临床疗效.方法 对15例脊柱转移癌行后路手术,切除受侵犯的椎板、椎弓根、小关节突,解除椎管内占位,同时应用椎弓根钉棒系统做相邻正常脊椎内固定,残存病椎直视下注射骨水泥进行强化,对患者治疗后受累的神经功能、疼痛及脊柱稳定等情况进行观察,分析该方法的治疗脊柱转移性骨肿瘤的效果.结果 本组患者神经功能改善率为80％,疼痛均得到不同程度的缓解,手术后脊柱稳定.结论 脊柱转移癌病灶位于附件及椎体后缘的病例,该方法手术损伤较小,手术时间短,可有效缓解局部疼痛及脊髓压迫症状,治疗效果较为满意.

Effect of spinal canal decompression and bone cement strengthening of vertebra in the treatment of vertebral metastatic tumor

Objective To investigate the effect of the treating metastatic vertebral malignant tumor by spinal canal decompression and bone cement strengthening of vertebra.Methods Fifteen patients of metastatic vertebrae malignant tumor were treated by decompression through posterior approach combined with pedicle nail-rod system fixation and injection of bone cement to the remnant damaged vertebra.The data of neural function,local pain and spinal stabilization pre-and post-operation were collected and evaluated.Results All the patients were followed up after operation.The amelioration rate of the damaged nerve function was 82%.The regional pain of all the patients was ameliorated,and no manifestations of spine instability were found.Conclusion For patients with lesion located in the posterior vertebrae,posterior decompression and internal fixation combined with bone cement injection to the damaged vertebra were preferred,with slight trauma,short operation time,and comparatively satisfactory result.
