퇴행성 요추질환에서 선택적 척추 신경근 차단술의 효용성

초록

Purpose: Authors investigated the usefulness of selective nerve root block (SNRB) in patients with herniated intervertebral disc (HIVD) and degenerative spinal stenosis. Materials and Methods: A total 148 patients whose symptoms were not improved by conservative treatment were treated by SNRB from Mar. 2013 to Oct. 2013. Degenerative spinal disease was divided into 2 groups: 72 (48.6%) with HIVD, 76(51.4%) with spinal stenosis. The degree of pain and activity were evaluated retrospectively by a Visual analogue scale (VAS) and Oswestry disability index (ODI). Results: The end-results of SNRB, with more than 50% reduction in pain occurred in 113 (76.3%) of the 148 patients: 59 (77.6%) with spinal stenosis and 54 (75.0%) with HIVD. The average number of SNRB was 2.1 (ranging from 1 to 10). The average VAS was 7.28 before SNRB and this decreased to 3.29 after SNRB (P<0.05). The average ODI was 50.2 before SNRB and this decreased to 42.3 after SNRB (P<0.05). There was not statistically significant difference in pain reduction after SNRB between HIVD and spinal stenosis. Conclusion: Selective spinal nerve root block in patients with lower back and radiating pain is reasonable treatment before surgery for degenerative lumbar disease.
