梨状肌病变与腰椎间盘突出症的关系

Relation between piriform muscle lesion and lumbar intervertebral disk protrusion

为探讨梨状肌病变与腰椎间盘突出症的内在关系，根据症状、体征及ｘ线检查结果将１１３例腰腿痛患者分为腰痛组和腰椎问盘突出症组，分别采用Ｂ超进行梨状肌探查。结果显示腰椎间盘突出症患者梨状肌异常明显高于腰痛组（Ｐ＜０．００１），在明梨状肌病变是腰椎间盘突出症的常见并发症。对梨状肌有无异常患者的病程统计结果表明，病程越长越易发生梨状肌病变。梨状肌异常患者治疗后复查结果表明，腰椎间盘突出症临床疗效与梨状肌病变的转好呈正比关系。

In order to explore the inner relation between piriform muscle lesion and lumbar intervertebral disk protrusion (LIDP), 113 cases of lumbago and scelalgia were divided into lumbago (U) and LIDP groups according to the symptoms,signs and radiographs,and given B-mode ultrasounic scanning,respectively. The results showed that LIDP patients had a much higher abnormal-piri-form-musele rate than U group (P<0. 001 ),proving piriform muscle lesion to be a frequently encountered complication of LIDP. The disease course statistlcs of patients with normal and abnormal piriform muscles showed the longer the course was,the easier the piriform muscle lesion occurred. The results of the post-therapeutic reexamination of the patients with abnormal piriform muscles showed a positive relation between the clinical results of LIDP and the improvements of piriform muscle lesion.
