Abstract: 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 preformulated indications. JOA scoring system for low backache was used to as sess 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.55% patients in the study were having JOA scores less than 19 preoperatively. On post-operative 3rd month 75% patients had scores 20 and above whereas on post-operative 6th month, the proportion was increased to 95%. On post-operative one year allpatients had scores more than 20.
Conclusion: Surgical treatment in patients of lumbar spinal stenosis yields good to excellent results as observed on the basis of JOA scoring system.
