摘要
设计了椎弓根钉钩板(PSHP)及其操作技术,能使腰椎滑脱复位及固定椎弓。手术步骤包括清理缺损处纤维组织,滑脱复位并固定椎弓,神经根减压和缺损两侧植骨。手术治疗12例,平均38岁。测量对比手术前后X线片的滑脱率(PS)、滑脱角(AS)和椎间盘指数(DI),术后PS明显减少,矫正率66%,AS接近正常椎间盘角,DI有一定程度增加。平均随访6.3个月。用日本整形外科学会评分标准评分(总分29分),术前平均17.3分,随访平均26.8分,改善率为81.2%。
The pedicle screws hook plates (PSHP)and the operative technique were designed to reduce slipping and fix the vertebral arch only. The main procedures of the operation include: clear fibrous tissue of the defect, reduction of the slipped vertebral body and fixation of the lytic arch, decompression of the nerve roots and bone grafting bilaterally of the defect. From July, 1993 to July, 1994, 12 patients were operated, the average age was 38 years. The percentage of slipping (PS) , the angle of slipping ( AS ) and the disc index (DI) measured on the roentgenograms between pre and postoperatively were compared. The PS decreased obviously in postoperation and the average of correction was 66%, the AS was closed to the normal angle of the disc, the DI increased in some extent. The avesage follow-up period was 6.3 months. Clinical evaluation was done with the score rating system of the Japanese Orthopaedic Association(total 29 points), preoperative average score 17.3 and follow-up average score 26.8. The improvement rate was 81.2%.
