Transforaminal Epidural Neuroplasty for Chronic Low Back Pain due to Spinal Canal Stenosis

People all over the world suffer from persistent low back pain, often caused by spinal canal stenosis. In long term cases of spinal canal stenosis, perineural adhesions can form and that further exacerbates the pain. Transforaminal epidural adhesiolysis is beneficial as it breaks down the adhesions and allows more precise delivery of drug to the targeted area. We present a case of 57 years lady with complaint of low back pain for 2 years radiating to left leg and associated with heaviness of left leg after walking for 5 minutes. MRI report and her clinical features were suggestive of canal stenosis at L4 and L5 level. Percutaneous epidural neuroplasty was done using Racz catheter via transforaminal subpedicular approach at L4-L5 level. The numeric pain rating scale before procedure was 7/10 and after procedure decreased to 3/10. Her walking distance also increased to 45 minutes in 1 month after the procedure.
