椎弓根螺钉内固定治疗多节段腰椎骨折的临床

目的 探讨应用TSRH-3D椎弓根螺钉系统复位并椎弓根内固定治疗多节段腰椎骨折的治疗效果及远期疗效.方法 本组18例多节段腰椎骨折患者应用TSRH-3D椎弓根螺钉系统复位并椎弓根内固定治疗多节段腰椎骨折,均于伤后4 h～2 d内手术,所有患者均得到随访,随访时间15～32个月,平均23个月.均于术前、术后、末次随访时拍摄脊柱正侧位X片和CT片.结果 (1)脊柱活动改善率为67%;腰背痛改善率为94%;下肢疼痛改善率为78%.(2)与术前相比,伤椎前缘高度平均矫正59.2%,平均丢失5.2%(P<0.01);Cobb角平均矫正19.5°,平均丢失5.4°(P<0.01)°结论 采用TSRH-3D椎弓根螺钉内固定系统治疗多节段腰椎骨折对损伤节段可有满意的复位及内固定效果,有利于恢复脊柱伤椎高度、生理弧度和神经功能以及消除腰腿痛,有较好的远期疗效.

Pedicle screw implanting in the treatment of multi-level lumbar spine fractures

Objective To review the clinical data of a group of patients with multi-level lumbar spine fractures treated with TSRH-3D pedicle screw system and to investigate the effect and post-operative efficacy of this technique. Methods Eighteen patients diagnosed as multi-level lumbar spine fracture were treated with TSRH-3D pedicle screw system. The operations were performed at 4 hours to 2 days after injury and the follow-up period was 15-32 months (mean; 23 months). The X-ray and CT scan were taken both preoperatively and postoperatively. Results ( 1 ) Twelve patients became injured from height falling (67%), 5 from traffic accident (28%) and 1 from crush (5%). (2) The improvement rate of spine motion, back pain and lower extremity pain was 67% , 94% and 78% respectively. (3) Compared with preoperative status, the height of anterior border of vertebra improved by 59. 2% , lost by an average of 5.2% (P<0.01) and the Cobb angle was corrected by 19.5°, lost an average of 5.4°. Conclusion It is feasible to treat the multi-level lumbar spine fractures with TSRH-3D pedicle screw system. And the outcome of reduction and fixation is satisfactory. This technique is excellent at improving the height of injury vertebra, physiological curvature and neural function. It also can relieve lumbocrural pain with a definite postoperative efficacy.
