Three degrees of acromioclavicular separation are commonly recognized. A Type III separation with entrapment of the clavicle on the top of the acromion is frequently not recognized while in its acute phase and amenable to closed reduction. The sign of this type of acromioclavicular separation is an apparent Type III in which one cannot manipulate the clavicle. The acute case is treated by local anesthesia, manipulation, and splinting. The chronic case is treated by excision of the outer end of the clavicle. In 1979 we treated three acute and one chronic superior entrapment of the clavicle on the acromion. During this time interval 67 acromioclavicular separations of Grade I, II, and III were treated. This amounted to 6% of our acromioclavicular separations treated during 1979.
肩锁关节分离通常分为三度。Ⅲ型分离伴有锁骨卡在肩峰顶部的情况，在急性期常常难以识别，但适合进行闭合复位。这种类型的肩锁关节分离的体征是看似Ⅲ型，即无法对锁骨进行手法操作。急性病例采用局部麻醉、手法复位和夹板固定治疗。慢性病例则通过切除锁骨外端进行治疗。1979年，我们治疗了3例急性和1例慢性锁骨卡在肩峰上方的病例。在此期间，共治疗了67例Ⅰ、Ⅱ、Ⅲ级肩锁关节分离。这占我们1979年治疗的肩锁关节分离病例的6%。
