Degenerative lumbar spinal disorder is common in Japan, and the L5 nerve root is commonly involved in this disorder. The symptoms of L5 radiculopathy are irradiating lateral leg pain, and numbness and weakness of tibialis anterior and the hip abductor muscle. There has been only one report on the results of surgery for hip abductor muscle weakness caused by degenerative lumbar spinal disorder.
In this study, we analyzed the strength of the hip abductor muscle before and after decompressive surgery in 26 cases and the relationship between the lumbar disc herniation (LDH) and lumbar spinal canal stenosis (LSCS) groups.
Of the total 26 cases, muscle strength improved in 23 cases (88%), with complete recovery in 17 cases (65%). In the LDH group, the improvement rate was 92%. In the LSCS group, the improvement rate was 68%. Although the improvement rate for the LDH group was higher than that for the LSCS group, the difference was not significant (P = 0.054).
Decompressive surgery may be an effective method to improve hip abductor muscle weakness in degenerative lumbar spinal disorder.
退行性腰椎疾病在日本较为常见，且第五腰椎神经根通常受累于此疾病。第五腰椎神经根病变的症状为放射状外侧腿部疼痛，以及胫骨前肌和髋关节外展肌的麻木和无力。仅有一篇关于退行性腰椎疾病导致髋关节外展肌无力手术结果的报告。
本研究分析了 26 例接受减压手术后髋关节外展肌力量的变化，并比较了腰椎间盘突出症（LDH）和腰椎管狭窄症（LSCS）两组之间的差异。
26 例患者中，23 例（88%）肌肉力量改善，17 例（65%）完全恢复。LDH 组的改善率为 92%，LSCS 组的改善率为 68%。虽然 LDH 组的改善率高于 LSCS 组，但差异无统计学意义（P = 0.054）。
减压手术可能是改善退行性腰椎疾病导致的髋关节外展肌无力的有效方法。
