Steffee椎弓根钢板治疗腰椎滑脱

Steffee Instrumentation Treatment for Spondylolisthesis

对12例腰椎滑脱伴有神经根症状的病人,采用Steffee器械复位固定,椎管和(或)神经根管减压,椎体间植骨术治疗。脊椎滑脱程度由29.9%(20～40%)减少到6%(0～15%),所有病人在术后3个月获得骨性融合且神经症状完全消失。作者认为Steffee器械的坚强固定有利于骨融合,有神经症状的脊椎滑脱宜行减压术。

Twelve patients of symtomatic spondylolisthesis were treated by Steffee instrumentation for the fixation of reduction combining the decompression of spinal and nerve root canals and posterior interbody fusion. The degree of vertebral slip was reduced from 29.9% (20～40%) to 6% (0～15%). The bone fusion occurred and the nerve symtoms relieved in all patients. It is indicated that the Steffee instrumentation of rigid fixation can enhance the bone fusion and the decompression should be performed on the symtomatic spondylolisthesis.
