Application of ultrasound-guided selective nerve branch blockage in lumbar spinal nerve posterior branch syndrome

Objective: To explore the clinical effect of the simple nucleus pulposus removal and small incision interlaminar window in the treatment of prolapsed and displaced lumbar disc herniation. Methods: From February 2016 to February 2018,35 patients with single-segment prolapse and displaced lumbar disc herniation were treated by the simple nucleus pulposus removal and small incision interlaminar window under general anesthesia. Among them,there were 21 males and 14 females;aged (42±17) years;27 cases of L_4,5 segment,6 cases of L₅S₁ segment,2 cases of L_3,4 segment;20 cases on the left side,13 cases on the right side. Modified Macnab standard was used to evaluate postoperative symptoms and functional recovery. Results: All the operations were successful and the operation time was 30 to 60 min with an average of 40 min,the intraoperative blood loss was 10 to 30 ml with an average of 20 ml. All the patients were followed up for 1 to 3 years with an average of 1.2 years. Thirty-five patients with low back pain and lower limb symptoms were significantly relieved or disappeared. According to modified Macnab standard,29 cases obtained excellent results,5 good,and 1 fair. Conclusion: Applying the concept of minimally invasive operation,small incision interlaminar window and simple nucleus pulposus removal for the treatment of prolapsed and displaced lumbar disc herniation has the advantages of short operation time,definite curative effect,and less trauma. And it is a safe and effective surgical method under the premise of strict control of the indications.
