URUCHI LIMACHI, Daniel Marcos  and  SEA ARAMAYO, Juan Marcelo. FUNCTIONAL EVALUATION BY OSWESTRY DISABILITY INDEX IN PATIENTS WITH POSTERO-LATERAL ARTHRODESIS FOR LUMBAR SPINAL STENOSIS. Rev. Méd. La Paz [online]. 2017, vol.23, n.2, pp.6-12. ISSN 1726-8958.

OBJECTIVES: To stablish the functional evolution and neurological condition through Oswestrydisability index (ODI)inthe biomechanics of the lumbar spine in patients who underwent neurological decompression and posterolateral arthrodesisand transpedicular screws stabilization by presenting lumbar spinalstenosis(LSS) in Obrero Hospital N° 1, La Paz city, Bolivia. To identify clinical, social and demographic factors of patients with degenerative lumbar spinal stenosis in which postero-lateral arthrodesis was performed. METHODS: A retrospective, descriptive and cross-sectional study between 2012 and 2014 was conducted. Patients who were treated with postero-lateral arthrodesis for lumbar spinal stenosis, in the traumatology service at Obrero Hospital in La Paz city were considered. We evaluated 16 patients who met the inclusion criteria. RESULTS: According to Oswestrydesability index, 56% of the patients have minimal functional limitation and 6% of disability at 6-month postoperative. The most affected gender were females with 57%, the average age was 64 years, prior time to surgical treatment was more than 12 months in 63%, and the most frequent instrumented levels were L3-L5 and L5-S1 with 25%. CONCLUSIONS: We performed decompressive surgical techniques: laminectomy, foraminotomy with instrumentation. Oswestry disability index helped to determine the applied techniqueswere effective. In most cases, patients displayed a functional evolution without limitations in their daily lives.
