Abstract
The Acromio-Clavicular joint (ACJ) is a synovial diarthrodial joint between the medial clavicular facet of the acromion and the distal end of the clavicle, the joint contains a fibro-cartilaginous disc that has been observed to vary considerably in size and shape. Its dislocations are common injuries of the shoulder girdle, especially in the young and active population. The most common mechanism for an ACJ disruption is falling directly onto the acromion with the arm in internal rotation and full abduction and/or falling directly on the superior aspect of the shoulder. Lesion severity depends on the displacement of the clavicle and coracoclavicular (CC) and acromioclavicular (AC) ligaments injuries Injuries to this joint are classified on the basis of the findings from the physical examinations and anteroposterior (AP) and axillary radiographs. Significant recent advances have been made in the approach to ACJ injury which is a consensus that type I and II ACJ injury should be treated non surgically, while acute type IV, V and VI injuries should be treated surgically, while the management of type-III injuries remains controversial but many studies do not show a significant difference in the clinical outcome between non surgically and surgically treated patients. Arthroscopic repair have recently been proposed for treating ACJ dislocations. It is hypothesized that arthroscopic techniques can reduce the morbidity and the early postoperative problems of this surgery, which is known for its complications, while providing anatomical and long-lasting reduction of the lesions. It can address concomitant pathology that may be encountered with an AC injury, and may be used to surgically address injured CC ligaments.
