Objective: The authors conducted this study to investigate the safety and efficacy of decompressive surgery alone in the treatment of lumbar spinal stenosis in the elderly population.
Methods:All charts and records of 323 patients aged 65 years or older who underwent lumbar spinal decompressive surgery without fusion for lumbar spinal stenosis in the period from September 2003 to August 2007 were reviewed.
Results:A total of 323 patients were identified. Mean age among patients were 72.6years. 197 patients(60.9%) underwent wide decompression, 95 patients(29.4%) had microscopic partial decompression, and 31 patients(9.5%) underwent bilateral decompression via unilateral approach. Perioperative morbidity seen was among 16 patients(4.9%). There were 5 patients(1.5%) reoperated for hematoma formation. Another 5 patients(1.5%) developed wound infection. Cerebrospinal fluid(CSF) leakage were noted among 3 patients(0.9%). 2 patients(0.6%) had urinary difficulty, and Steven Johnson syndrome developed in one patient(0.3 %). Clinical outcome was evaluated using Macnab’s classification. 40 patients(12.4%) had excellent results, 241 patients(74.8%) had good results, 34 patients(10.3%) had fair results and 8 patients(2.5%) had poor outcome.
Conclusions: Decompressive laminectomy alone is a relatively safe and effective treatment option for the elderly.
