Abstract

To determine the efficacy of transforaminal selective nerve root block in patients with monoradicular pain due to lumbar disc herniation. Methods: It was prospective study which included 156 patients coming to Shyam Shah Medical College, Rewa. Patients with monoradicular pain coming to Outpatient department were evaluated with history, clinical examination, Spine radiographs and MR studies. Patients with acute onset pain, no neurological deficit, no instability in dynamic X-rays and single level disc herniation on MRI corresponding to the symptomatic nerve root were included in the study. After anaesthesia fitness transforaminal selective nerve root block were given by a single spinal surgeon. The patients were assessed in follow up after two weeks, three months and six months. Improvement in radicular pain was assessed by VAS scoring system. In case of persistent symptoms, patients were given the option of a repeat selective nerve root block or conventional microdiscectomy. Results: At six-month follow-up of the 156 patients, 106 patients had a favorable outcome (85 after one block and 21 after two blocks), and only 33 required surgery. Conclusion: Our study suggest a good efficacy of transforaminal selective nerve root block for the treatment of monoradicular pain in patients with lumbar disc herniation
