Objective To evaluate the effect of bilateral multiple segmental decompressive interlaminectomy in the treatment of lumbar stenosis in elderly individual. Methods 25 cases of elderly lumbar stenosis were treated by bilateral multiple segmental decompressive interlaminectomy. Results 25 cases were followed up for 1～3 years. All the patients with neurogenic intermittent claudication in this group were ameliorated.6 of 7 cases with repititive lower back pain were improved.The lower extremity nerve root pain in 9 cases disappeared completely. 5 of 8 cases with skin sensitive decrease were recovered.3 of 4 cases with hallus dorsal extension weakness were recovered.According to Nakal score system, the results were excellent in 18 cases, good in 4, fair in 2 and poor in 1. Conclusion Bilateral multiple segmental decompressive interlaminectonmy is safe and simple in operation, which is one of the effective methods to treat lumbar stenosis in elderly individuals.
