Abstract：
Lumbar sympathetic blocks (LSBs) are used to treat sympathetically mediated pain in the lower extremities, kidneys, ureters, and genitals. LSBs use local anesthetic to block the sympathetic system to modulate pain response. In this case report, an avid runner was diagnosed with synovial plica syndrome. His pain was refractory to arthroscopic plica excision, physical therapy, nonsteroidal anti-inflammatory drugs, and intraarticular steroid injections. He received 3 rounds of LSB resulting in significant and sustained pain relief. This case suggests that LSB successfully treated knee pain from synovial plica syndrome and there may be a sympathetic component to this disease state.
摘要：
腰交感神经阻滞（LSB）用于治疗下肢交感神经介导的疼痛，肾脏，输尿管,和生殖器。LSB使用局部麻醉剂来阻断交感神经系统以调节疼痛反应。在这个案例报告中,一名狂热的跑步者被诊断为滑膜皱折综合征。他的疼痛是关节镜下皱褶切除难治的，物理治疗,非甾体抗炎药，关节内注射类固醇.他接受了3轮LSB,导致显著和持续的疼痛缓解。此病例表明LSB成功治疗了滑膜皱折综合征引起的膝关节疼痛，并且该疾病状态可能存在交感神经成分。
