Background: Lumbar canal stenosis is a disease of advanced age, commonly seen in individuals >60 years of age. The disease begins with neurogenic claudication and is progressively associated with weakness in the lower limbs. Often, these patients also have radiculopathy, which may be due to a contribution of foraminal stenosis and facet arthropathy.
Methods: This research has been conducted on a sample of patients presenting to our tertiary care center with lumbar canal stenosis to evaluate the outcome of transforaminal epidural steroidal injection and to determine the therapeutic response of the patient in response to the epidural steroidal injection. A sample of 49 patients presenting with neurogenic claudication of 6 weeks duration (minimum) in correspondence with MRI finding suggestive of lumbar canal stenosis were chosen after obtaining informed consent for the procedure transforaminal epidural steroidal injection under fluoroscopy. Pre- and post-NRS scores were recorded at 2 instances.
Results: The mean and standard deviation of pre-procedural and immediate post-procedural NRS scores were found to be 7.02±1.62 and 3.12±1.2 respectively. The mean and standard deviation of the 1-month post-procedure NRS was found to be 3.27±1.56. Considering successful treatment as more than 50% reduction in the NRS score at 1 month when compared to the pre-treatment NRS score, the successful outcome of the study was 63.26%.
Conclusions: In our study, we have evaluated the effect of TEFSI in patients with lumbar canal stenosis presenting with neurogenic claudication and radiculopathy. Our study assessed pre-procedure, immediate post-procedure, and 1-month post-procedure NRS score following TEFSI. NRS score was assessed based on a questionnaire. The reduction of NRS score was equally seen in all patients irrespective of age, sex, and complaints.
