中英文字幕：肩关节脱位（Shoulder Dislocation）

　　肩关节是最常发生脱位的关节，约占全身关节脱位的50％，这与肩关节的解剖和生理特点有关，如肩关节盂浅而小，对肱骨头包容少，关节囊松弛，关节活动范围大，周围软组织薄弱，遭受外力的机会多等。

Shoulder Dislocation

肩关节脱位

Overview（概述）

The shoulder is a ball-and-socket joint. The ball of your upper arm bone fits into a socket in your shoulder blade. If the ball slips out, your shoulder has 'dislocated.'

　　肩关节是“球臼”关节。上臂骨头的球部与肩胛骨的窝相匹配。如果球滑到外面，就是所谓肩关节脱位。

Causes（原因）

You can dislocate a shoulder if you fall on your arm, or get hit hard. It can happen during a road accident. You can dislocate a shoulder playing football or volleyball. Skiiers and gymnasts also have a higher risk.

　　当摔倒时上臂着地或肩部受到剧烈撞击，就可能发生肩关节脱位。交通事故、踢足球或打排球时也会发生肩关节脱位。滑雪和体操也有很高的风险。

Symptoms（症状）

A dislocated shoulder causes pain. You may not be able to move your arm. Your shoulder may swell or bruise. And you may see a bump under your skin where the ball has shifted.

　　肩关节脱位会引起疼痛，不能活动胳膊，肩关节会肿胀及淤青。在球移位处可看到皮下有隆起。

Treatment（治疗）

A doctor resets the joint by moving your arm into different positions to put the ball back in place. Medication and an arm splint or a sling may help the shoulder heal. Physical therapy may help. If you have a severe dislocation, or if it happens a lot, you may need surgery. Your healthcare provider can create a care plan that is right for you.

　　医生通过将上肢放在不同的位置将球重新放回复位关节。药物、上肢支具或吊带有助于肩关节愈合。物理治疗有帮助。如果脱位严重，或多次发生，可能需要手术。医学专家会制定合适的计划。
