目的探讨椎弓根螺钉复位固定及单侧后路植骨融合术治疗腰椎滑脱症的疗效.方法本组采用椎弓根螺钉将滑脱椎体提拉复位,一侧半椎板减压,另一侧椎板植骨融合治疗腰椎滑脱症28例.其中退变型18例,峡部型10例.L4滑脱20例,L5滑脱8例,其中Ⅰ度20例,Ⅱ度8例.结果术后随访6～60个月,根据Nakai分级:优20例,良4例,可4例,优良率85.7%.25例达到骨性融合,融合率为89.3%,平均融合时间为4个月(3～6个月).结论椎弓根螺钉复位固定加单侧后路植骨融合术是治疗只有一侧神经根性症状的腰椎滑脱症的一种有效方法.该方法操作简便、损伤小、出血少.
Objective To investigate the therapeutic effect of pedicle screw internal fixation and unilateral laminar fusion on lumbar spondylolisthesis. Methods Twentyeight patients hospitalized from Jan. 1999 to Dec. 2003 were included who having chronic low back pain or repeated attacks with Ⅰ°or Ⅱ°spondylolisthesis. Eighteen of them were the degenerative type, and 10 were isthmic type. Twenty were in L4.5 and 8 were in L5S1. Twenty were Ⅰ°and 8 were Ⅱ°. Results The patients were followed up for an average period of 2 years （6 months-5 years）. Twenty were excellent, 4 were good and 4 were fair. The rate of excellent and good was 85.7%. The overall fusion rate was 89.3%. The average fusion time was 4 months （3-6 months）. Conclusion Surgical operations are often required for spondylolisthesis accompanied with radicular symptoms or refractory with conservative treatment. The operation of pedicle screw fixation plus unilateral laminar fusion achieves anatomic reduction, enlarges the stenotic spinal canal and preserves a unilateral lamina with local bony graft fusion to reach an even better stability. The procedure is easy to operate, cause little trauma and get satisfactory result.
