Abstract:
Stabilization of the unstable spine created by the posterior decompression is as important as the decompression itself in the treatment of spinal stenosis. The purpose of this study is to evaluate the effectiveness of C-D pedicle screw fixation in stabilization after lumbar decompression, in reduction of spondylolisthesis and in restoration of the lumbar sagittal curvature. C-D pedicle screw fixation was performed in 102 spinal stenosis patients after posterior lumbar decompression and fusion during the period from March 1987 to December 1988. Their age ranged from 15 to 72 years with an average of 49.1 years. There were 34 males and 68 females. The follow up was from 6 to 21 months with an average of 12.5 months. The causes of spinal stenosis were degenerative in 50 patients, spondylolisthesis in 39, iatrogenic in 9 and degenerative lumbar scoliosis in 4. Objective clinical results showed significant improvement of claudication, SLR limitation, motor weakness, sensory and DTR changes in most patients. Following results were obtained from the study of C-D pedicle screw fixation after posterior decompression in lumbar spinal stenosis.1. C-D pedicle screws provide the secure fixation that allows early ambulation and shorter hospital stay. 2. C-D pedicle screws enable the reduction of spodylolisthesis at the time of posterior stabilization. 3. C-D pedicle screw fixation is successful in the restoration and maintenance of sagittal curvature of the lumbar spine. 4. C-D pedicle screw fixation enables the correction of scoliosis at the time of posterior decompression.
