Minimally invasive lumbar spinal decompression in the elderly: outcomes of 50 patients aged 75 years and older.

摘要: OBJECTIVE: Lumbar spinal stenosis and spondylosis are major causes of morbidity among the elderly. Surgical decompression is an effective treatment, but many elderly patients not considered as candidates for surgery based on age or comorbidities. Minimally invasive surgical techniques have recently been developed used successfully treatment lumbar disease. Our objective was to examine safety efficacy minimally patients. METHODS: We reviewed demographic information, pre- postoperative Visual Analog Scale pain scores, Oswestry Disability Index Short-Form 36 scores prospectively accrued who underwent degenerative disease at two institutions between January 2002 December 2005. Data from were least 75 years old selected. Statistical analysis methods included paired t test, multiple linear regression, mixed effects modeling. RESULTS: Fifty-seven with a mean 81 met study criteria (median follow-up period, 7 mo; 10 mo). No complications deaths occurred. Fifty had sufficient outcomes data analysis. decreased 5.7 2.2 back 2.3 symptomatic leg (P < 0.05). 48 27; Body Pain Physical Function also showed statistically significant improvements after The longitudinal demonstrated durability symptom relief. CONCLUSION: spine safe efficacious spondylosis. Elderly should be good using techniques.
