It has been reported that compression of the sciatic nerve because of any cause, including endometriosis, piriformis syndrome, abscess, tumor, adjoining uterus provoke sciatic pain. Some of these pathophysiologies have been diagnosed clinically and sometimes by exclusion.
To discuss the clinical features of sciatic neuropathy under the belief that dynamic motion of the obturator internus muscle and tendon should be included in the differential diagnosis of sciatic neuropathy.
Sciatic neuropathy, which was because of compression of the sciatic nerve caused by dynamic motion of the tendon and muscle of the obturator internus, was reported.
We performed surgery to confirm the outlet of the pelvis.
Although no compression was provoked by the piriformis muscle, obvious compression was observed on the sciatic nerve by the stretched obturator internus muscle.
Although it may not be common, compression of the sacral plexus caused by dynamic motion of the obturator internus muscle should be included as a possible diagnosis for sciatic pain.
据报道，任何原因导致的坐骨神经受压，包括子宫内膜异位症、梨状肌综合征、脓肿、肿瘤、毗邻子宫等，均可引发坐骨神经痛。其中一些病理生理情况已通过临床诊断，有时也通过排除法诊断。
探讨坐骨神经病变的临床特征，认为闭孔内肌和肌腱的动态运动应纳入坐骨神经病变的鉴别诊断。
报告了因闭孔内肌腱和肌肉的动态运动导致坐骨神经受压引起的坐骨神经病变。
我们进行手术以确认骨盆出口。
尽管梨状肌未引起压迫，但伸展的闭孔内肌对坐骨神经有明显压迫。
尽管可能不常见，但闭孔内肌动态运动导致的骶丛受压应作为坐骨神经痛的一种可能诊断。
