  • Title: Wide versus selective decompression in the operative treatment of lumbar spinal stenosis.
    Author: Yu CS, Tay BK.
    Journal: Singapore Med J; 1992 Aug; 33(4):378-9. PubMed ID: 1411669.
    Abstract:
    The early post-operative results of wide versus selective decompression in a group of 64 patients with lumbar spinal stenosis were studied with the aim of ascertaining whether a more limited approach gives comparable results to the more traditional method of wide decompression. Wide decompression involved complete removal of a vertebral lamina at the stenotic level. Selective decompression refers to removal of the lower part of the superior lamina and the upper part of the inferior lamina at the stenotic level together with limited facetectomies. Patients were compared with respect to post-operative relief of back pain and sciatica/claudication as well as the ability to return to their pre-morbid level of functional activity. Follow up ranged from 4 months to 26 months. Results showed that both wide and selective decompression were able to achieve complete or considerable relief of symptoms and return to pre-morbid level of activity in 74% to 84% of patients. The results in the 2 groups were not statistically different. It appears that within the first 2 years of surgery, the vast majority of our post-decompression patients had good results regardless of whether wide or selective decompression was used.
