摘要
目的 :探讨椎弓根钉加压植骨治疗腰椎峡部不连并轻度滑脱的疗效及原理。方法 :自1989年起治疗 2 5例 5 0处病变 ,随访 8个月～ 6年 6个月 ,平均 3.7年。结果 :5 0处均获得骨性融合 ,计优2 3例 ,良 2例。结论 :椎弓根钉加压植骨融合术与其他融合术相比 ,对腰椎的正常生理活动范围干扰及手术创伤较小 ,操作技术亦相对简单 ,不需要外固定 。
objectives: To investigate the clinical results of the pedicle screw compressed grafting for treatment of spondylolysis and spondylolisthesis. Methods: 46 patients with 50 defects had been treated with this new technique since 1989. The average period of follow up were 43 months (8～78 months). Results: Fifty defects gained bone fusion 23 patients were in excellent, and good. Bone grfting in the efects achieved fusion between the loose lamina and the anterior element of lumbar vertebrae and reconstructed the anatomic structure and physiological function of the lumbar vetebrae. Conclusions: Comparison with other fusion procedures, this operation is technically simple and does no sacrifices of lumbar motion ranges, and lumbar cast is not applied. Isthmic grafting repairing is indicated in spondylolysis plus mild spondylolysis and spondylolisthesis.
