ABSTRACT

Objective To analyze the effectiveness of laminectomy decompression compared with vertebral lamina decompression combined with lumbar fusion in Degree I spondylolisthesis and spinal canal stenosis. Methods PubMed, Science Direct Online, Springer, CNKI, Wan Fang and VIP were retrieved to collect relevant randomized controlled trials( RCT) . According to inclusion and exclusion criteria,two researchers screened literatures, extracted data and evaluated quality. RevMan5. 0 software was used for Meta analysis. A total of 11 RCT were included,with a total of 1684 patients. Meta analysis showed that compared with the simple laminectomy group,the VAS score of lumbar pain in the lumbar fusion group at 1 years after operation decreased ( MD and 95％CI-1. 20(-1. 57--0. 83) ,P<0. 05) ,and the VAS score of the 1 year postoperative leg pain in the lumbar fusion group decreased(MD and 95％CI-0. 88(-1. 32- -0. 44),P<0. 05),the excellent rate of lumbar fusion group at 2 years after operation was higher( OR and 95％CI1. 65( 1. 13-2. 41) ,P<0. 05) . There was no significant difference in postoperative complications and lumbar spondylolisthesis at 1 years after operation. Conclusion In long term, compared with decompression alone, vertebral lamina decompression combined with lumbar fusion has more ideal effectiveness in the treatment.
