Functional Outcome of Surgical Management of Lumbar Spinal Stenosis
Aims and Objectives: To determine the functional outcome after surgical management of lumbar spinal stenosis. Materials and Methods: In this study 20 patients of lumbar spinal stenosis were enrolled. All the Patients were managed with three different surgical techniques according to pre-formulated indications. JOA scoring system for low backache was used to assess the patients. The recovery rate was calculated as reported by Hirabayashi et al. (1981). Surgical outcome was assessed on the recovery rate and was classified using a four grade scale: Excellent, improvement of >90%; good, 75–89% improvement; fair, 50–74% improvement; and poor, below 49% improvement. The patients were evaluated post-op at 3 months, 6 month and one year follow-up. Results and Discussion: Total 50% patients were having good functional outcome whereas 10% had excellent outcome. Fair outcome was observed in 35% patients and poor in 5% patients.
