| acromioclavicular disk | The articular disk of fibrocartilage usually found between the acromial end of the clavicle and the medial border of the acromion. Synonym: discus articularis acromioclavicularis, acromioclavicular disk, Weitbrecht's cartilage. (05 Mar 2000) |
| acromioclavicular dislocation | <orthopaedics> Disruption of the normal articulation between the acromion process and the clavicle. The acromioclavicular joint (AC joint) is normally stabilised by several ligaments that can be torn in the process of dislocating the AC joint). See: acromioclavicular sprain. (27 Sep 1997) |

| acromioclavicular ligament | <anatomy> A fibrous band extending from the acromion of the scapula to the clavicle. Synonym: ligamentum acromioclaviculare. (05 Mar 2000) |
| acromioclavicular sprain | <orthopaedics> A shoulder injury where the ligaments which stabilise the articulation of the acromion process and the clavicle become torn (sprain). A classic lump deformity is noted on the top contour of the shoulder in more serious sprains. Acromioclavicular separations occur most often after a direct fall onto the shoulder. Severe sprains may result in acromioclavicular dislocation. (15 Jan 1998) |
| articular disc of acromioclavicular joint | The articular disk of fibrocartilage usually found between the acromial end of the clavicle and the medial border of the acromion. Synonym: discus articularis acromioclavicularis, acromioclavicular disk, Weitbrecht's cartilage. (05 Mar 2000) |
