How can the answer be improved? acromioclavicular joint subluxation classification A separated shoulder, also known as acromioclavicular joint injury, is a common injury to the acromioclavicular joint. The AC joint is located at the outer end of the clavicle where it attaches to the acromion of the scapula. Symptoms include pain which may make it difficult to move the shoulder and often a deformity. It is most commonly due to a fall onto the front and upper part of the shoulder when
Classification Type I: Sprain of the acromioclavicular or coracoclavicular ligament Type II: Subluxation of the acromioclavicular joint associated with a tear of the acromioclavicular ligament; coracoclavicular ligament is intact. acromioclavicular joint subluxation classification
CLASSIFICATIONS OF ACROMIOCLAVICULAR JOINT INJURIES: The most common classification is the Allman and Tossy classification (Allman, 1967; Tossy et al. , 1963) with injuries type 1, 2 or 3 with Rockwoods modification, which added 4, 5 and 6 to complete the classification (Rockwood et al. , 1998). 7 rows Classification: Description: Notes: Type 1: AC Joint strain: Normal radiograph: Type 2: AC acromioclavicular ligament. provides horizontal stability; has superior, inferior, anterior, and posterior components When performing an arthroscopic distal clavicle excision for acromioclavicular joint arthrosis, which of the following structures must be preserved to prevent postoperative anteroposterior instability of the clavicle? acromioclavicular joint subluxation classification Rockwood classification of acromioclavicular joint injury type I: clavicle not elevated with respect to the acromion. type II: clavicle elevated but not above the superior border of the acromion. type III: clavicle elevated above the superior border of the acromion but coracoclavicular distance An AC Joint Subluxation is a partial dislocation, meaning that the clavicle goes partially out of joint, with part of the clavicle still touching the acromion. An AC Joint Subluxation looks like a small bump on top of the shoulder. Clinically Relevant Anatomy. The acromioclavicular joint is surrounded by a capsule and reinforced by the superiorinferior capsular ligaments with the coracoclavicular ligaments (trapezoid and conoid) also important structures for stability of the joint. Acromioclavicular Joint Separation Classification. Acromioclavicular and coracoclavicular ligaments disrupted with inferior dislocation of the distal clavicle inferior to the coracoid process and posterior to the biceps and coracobrachialis tendons.
