摘要
目的:探讨经伤椎置钉固定治疗单节段胸腰椎骨折的临床疗效。方法:采用后路单节段椎弓根螺钉复位固定结合植骨融合的方法治疗胸腰椎骨折患者18例,比较患者术前和术后的Cobb角、椎体压缩百分比及椎管矢状径占位率,用Frankel分级评估神经功能。结果:18例均获得随访,无一例内固定松动和断裂,全部获得骨性融合;术后伤椎Cobb角、椎体压缩百分比及椎管矢状径占位率均较术前明显改善(P<0.01)。Frankel分级:术前B级2例,C级5例,D级7例,E级4例;术后C级3例,D级8例,E级7例。结论:后路椎弓根螺钉复位固定结合植骨融合治疗单节段胸腰椎骨折是一种疗效确切、安全可靠的内固定方法,但应严格掌握适应证。
Objective： To evaluate the efficacy of monosegment fixation in the treatment of thoracolumbar fractures. Methods： A total of 18 patients with thoracolumbar fractures were treated with monosegmental pedicle instrumentation and bone graft fusion. The Cobb angle of the injured vertebral segment,percentage of the vertebral compression and the spinal canal sagittal diameter stenosis rate were compared before and after the operation. Neurological function was evaluated by the Frankel scale. Results： All the 18 patients were followed up. All the cases achieved bone fusion with no significant lose of the vertebrae body height or implant failure. X-ray film showed that the cobb angle of the injured vertebral segment,percentage of the vertebral compression and the spinal canal sagittal diameter stenosis rate improved significantly after operation（ P〈0. 01）. As to the Frankel scale,there were 2 patients at Grade B,5 at Grade C,7 at Grade D and 4 at Grade D before operation; and there were 3 patients at Grade C,8 at Grade D and 7 at Grade E after operation.Conclusions： The transpedicular fixation through posterior approach combined with bony graft is an effective and reliable procedure for specific types of thoracolumbar vertebral fractures,but strict indication is the key to this procedure.
