Comparative Study
The effect of limited interlaminar decompression versus complete laminectomy on intrathecal volume in degenerative lumbar spinal stenosis.
There is a controversial discussion about the adequate surgical procedure for degenerative lumbar spinal stenosis. Due to the observation that the degenerative lumbar spinal stenosis takes place predominantly at the interlaminar region on the level of the disc involving facets and bulging of the ligamentum flavum, resection of the whole lamina might not be necessary. A biomechanical study was designed to assess the effect of different decompression techniques using cadaver lumbar spine models. ⋯ The results allow to conclude that limited interlaminar decompression is efficient for decompression in degenerative lumbar spinal stenosis.
