腰椎板减压术后对脊柱稳定影响的临床分析

Clinical Analysis of Spine Stability after Posterior Decompression for Degenerative Lumbar Canal Stenosis

１９８８年２月至１９９４年５月，作者采用椎板减压术治疗退变性腰椎管狭窄症４８例，对４６例进行回顾性分析，平均随访时间３年２月。４例原有滑脱范围增加，５例发生滑脱，但术后症状均有改善，手术效果同无滑脱组相比无明显差别。因此认为对退变性腰椎管狭窄症做充分后路减压的同时应尽量保留外侧半小关节，常规植骨融合意义不大。

From 1988 to 1994, 48 cases of the degenerative lumbar canal stenosis had been treated with posterior decompression without fusion of the lumbar spine. 46 cases had been followedup for 3 years and 2 months and the retrospective analysis was made. It was found that the range of original vertebral slipping became larger in 4 cases. The lumbar slipping was happened in 5 cases. The symptomes in all of them were improved after the operation and there was no obvious difference in the operative effect as compared with the cases without lumbar slipping. The causes of slipping were discussed. The writers suggested that it is important to reserve the lateral half of facet joint as much as possible while adequate posterior decompression is applied to degenerative lumbar canal stenosis and that there is no great significance for the routine application of spinal fusion.
