To assess the indications for using pedicular screwing (PS) for lumbar arthrodesis, we compared 25 cases treated with PS with 47 cases posterolateral fusion (PLF) cases.
The PS gained significantly better clindcal results than the PLF Group, due to relief of low back pain (LBP). The group also achieved good bone union and reduction of movement or olisthesis of the unstable segment. However developed some new olistheses lower adjacent segment.
We concluded that the use of PS should be limited to: 1) middlu aged patients 2) unstable segments with LBP 3) For patients without multiple degenerative segments.
