为肩部疼痛的另一个来源：难道是AC接头？

肩袖撕裂，肩周炎和冲击是可以在肩部产生功能障碍都非常普遍，公知的条件。较不常见的，但仍可能有问题的，并因此确定的肩部疼痛源时肩峰锁骨（AC）联合另一个重要的考虑因素。

肩关节的解剖

锁骨（锁骨）具有2个关节内侧（向胸骨）和横向端部（肩胛骨肩的肩峰）。交流关节是指与肩胛骨的肩峰的横向关节运动。接头经由肩锁，喙肩和喙锁韧带和斜方肌的上部和中间纤维以及三角肌稳定。

肩关节的损伤

Acromion clavicular (Ac) joint dysfunction is a result of a sprain, dislocation, fracture or osteoarthritis at this joint

脱位和扭伤

交流关节通常是由直接坠落伤到肩膀的顶部，骑自行车受伤，或高架投掷（标枪）运动员有关。肩胛骨（肩胛骨）向下强制和锁骨（锁骨）出现突出。损伤的在接合的程度是由关节和损坏的韧带支持它的分离分类。扭伤表明韧带损伤而错位指锁骨向上和向后移出其正常对准的。锁骨和肩峰之间的这种分离程度分级上的6点量表，以3-4级或更高需要手术。

The altered position of the clavicle disrupts the normal rotation action of the clavicle that is required to achieve end-range forward flexion (overhead ROM). The pain will occur as a result of overstretched/ ruptured ligaments (depending on the severity) and a stretched joint capsule. As a protective mechanism, pain tends to lead to altered postures which may contribute to neck pain and altered muscles activity of muscles that attach to the clavicle; such as the pecs, trapezius and sternocleidomastoid.

Fracture of the collar bone

The fracture may occur at the distal end of the clavicle following contact sports injuries, bicycle and car accidents.

关节炎of the acromion clavicular joint

于本联合关节炎的发病率已经被证明是老年人口的MRI研究约50％，但是，这些人可无症状。

Just like any arthritis, this refers to degeneration of the cartilage at the ends of the clavicle and acromion. Normal day-to-day activities that require repetitive arm motion can cause cartilage loss (primary osteoarthritis). In addition, arthritis may be due to cartilage degeneration after an injury to the joint (post-traumatic arthritis). Regardless of the cause, predominately the normally smooth cartilage, as well as the meniscus between the bones breakdown leading to pain, due to increased friction and thus creating an inflammatory response at the joint.

Signs and Symptoms of Acromion clavicular Dysfunction

关节炎

最初的疼痛可能是整个肩膀普遍，直到急性期做出决议，以下这个阶段的人将在锁骨结束的现场演示具体的压痛。肿胀和取决于损伤的台阶畸形的程度可能是可见的。这是一个明显的肿块在万向节被破坏（如在错位的情况下），并在更严重的伤害被认为是。类似arthhiritis个人将上移动肩膀报告疼痛，尤其是活动的开销，并在您的身体运动。

Treatment of Acromion Clavicular Dysfunction

Acute injuries will respond to ice therapy, anti-inflammatory medications and a sling are often used.

电疗可以被利用来防止瘢痕组织在韧带的形成，促进愈合和减少肿胀。

运动疗法恢复的强度和范围这两个颈部的运动和肩部是至关重要的。加强练习包括横向旋转的工作，以及肩胛骨捏练习。

Taping can be applied to offload and realign the Ac joint.

在痛苦的范围的交流接头（锁骨）的动员是也由理疗师以恢复正常的和无痛苦的对准共同的干预。
