Abstract
BACKGROUND: Lumbar stenosis is a common degenerative spinal disease of the lumbar spine. The aim of our observational prospective study is to evaluate the long-term outcome and reoperation rate (RR) after microsurgical bilateral decompression via unilateral approach (BDUA) for lumbar spinal stenosis (LSS).
METHODS: Nine hundred and eighteen patients were treated for single or multilevel LSS by BDUA between January 2002 and January 2016. 180 patients of the 918 underwent microdiscectomy with decompression. They were then followed up postoperatively, at 6 and 12 months with radiological investigations, Oswestry Disability Index (ODI) and 36-item short-form health survey (SF-36) tests.
RESULT: Four hundred and ninety-two patients were females (53,6%), four hundred and twenty six were males (46,4) whose mean age was 63,83±10,16 (range: 43-79 years). Duration of symptoms ranged from 4 to 49 months. Average follow-up time was 98 months (range 25-168 months) and the RR was 2,5%. The ODI scores decreased significantly (30.65± 7.82, to 11.32 ± 2.50 at six months and 11.30 ± 2.49 at first year) and the SF-36 parameter scores demonstrated a significant improvement in the early and late follow-up results.
CONCLUSIONS: BDUA for LSS allowed a sufficient and safe decompression of the neural structures, resulted in a highly significant reduction of the symptoms and disability, acceptable RR, and improved health-related quality of life.
