Comparative Study
Outcome of posterolateral fusion versus circumferential fusion with cage for lumbar stenosis and low degree lumbar spondylolisthesis.
To evaluate the outcome of two methods for stabilization and fusion: posterolateral fusion and circumferential fusion involving posterior lumbar interbody fusion for lumbar stenosis with Grades 1 and 2 lumbar spondylolisthesis. ⋯ The first choice of surgical method for lumbar stenosis with low degree lumbar spondylolisthesis is instrumented posterolateral fusion. Only when patients suffer from severe preoperative disc degeneration and low back pain or intervertebral instability should we consider indications for additional use of CAGE.
