梨狀肌綜合征可刺激、壓迫坐骨神經(jīng)痛，引起下肢疼痛、麻木、無(wú)力等癥狀，與腰椎間盤源性腰腿痛癥狀相似，容易誤診。

Piriformis syndrome occurs when the piriformis muscle spasms and irritates or compresses the sciatic nerve. It often causes symptoms similar to sciatica, though it is not caused by a spinal problem like sciatica is.

       梨狀肌綜合征是梨狀肌痙攣、激惹和壓迫坐骨神經(jīng)所引發(fā)的病癥。它所引起的癥狀與坐骨神經(jīng)痛相似，盡管不象坐骨神經(jīng)痛一樣由脊柱疾病引起。

The piriformis is a small muscle located deep in the buttock, behind the gluteus maximus. It runs diagonally from the lower spine to the upper surface of the femur, with the sciatic nerve running underneath or through the muscle. The piriformis muscle helps the hip rotate, turning the leg and foot outward.

       梨狀肌是位于臀部深層的一塊小肌肉，在臀大肌深面。它從脊柱底端斜向股骨近端的表面，坐骨神經(jīng)從該肌下方或中間穿過(guò)。梨狀肌幫助髖關(guān)節(jié)旋轉(zhuǎn)，使下肢和足外旋。

As a result of overuse, injury, or strain, the piriformis muscle can tighten, swell, or spasm. Sports that involve repetitive forward movement of the legs,  or problems in surrounding joints like the sacroiliac joints are typical causes of piriformis syndrome.

       當(dāng)梨狀肌過(guò)度使用、損傷或拉傷，會(huì)緊張、腫脹或痙攣。那些反復(fù)作下肢向前活動(dòng)的運(yùn)動(dòng)以及象骶髂關(guān)節(jié)等關(guān)節(jié)周圍的疾患，常常引起梨狀肌綜合征。

The location of the piriformis muscle near the sciatic nerve means that when the piriformis muscle is irritated or injured, it can affect the sciatic nerve as well.

       梨狀肌的位置與坐骨神經(jīng)相鄰，意味著當(dāng)梨狀肌受激惹或受傷，也會(huì)影響到坐骨神經(jīng)。

Symptoms of piriformis syndrome include tenderness and pain in the buttock area, accompanied by sciatica-like pain, numbness, and weakness that runs down the back of the thigh, calf, and foot. Pain from piriformis syndrome is often worse when walking up stairs, after sitting, or while walking or running.

       梨狀肌綜合征的癥狀包括臀部的壓痛和疼痛，伴有坐骨神經(jīng)痛相似的沿大腿后方、小腿和足的疼痛、麻木、乏力。由梨狀肌綜合征引起的疼痛往往在上樓梯、坐過(guò)以后、行走或跑步時(shí)加重。

Piriformis syndrome is often confused with other conditions, especially lumbar spine conditions. Attaining a proper diagnosis of piriformis syndrome is important when considering treatment for low back and leg pain.

       梨狀肌綜合征常與其它疾病相混淆，尤其是腰椎疾患。當(dāng)考慮治療腰腿痛時(shí)，正確診斷出梨狀肌綜合征是非常重要的。
