Since then, distal clavicular osteolysis (DCO) has been sepa- rated into traumatic and atraumatic pathogeneses. In 1982 the frst series of male weight trainers who developed ADCO was reported. The association of weightlifting and ADCO is espe- cially important considering how routine a component weights are to the male athlete's training. The pathogenesis of DCO has often been debated. The most widely accepted etiology involves a connection between microfractures of the subchondral bone and subsequent attempts at repair, which is consistent with repetitive microtrauma. Symptoms usually begin with an insidious aching pain in the AC region that is exacerbated by weight training. On examination, patients have point tenderness over the affected AC joint and pain with a cross-body adduction maneuver. Although DCO may seem like an easy and quick diagnosis, one must rule out other possibilities. Avoidance of provocative maneuvers, modifcation of weight training techniques, ice massage, and nonsteroidal anti-infammatory drugs (NSAID) constitute the basis of initial treatment. Much of the literature supports the same general indications for surgery. These include point ten- derness of the AC joint, evident abnormal signs with AC joint scintigraphy and AC radiographs, lack of response to conserva- tive treatment, and an unwillingness to give up or modify weight training or manual labor. Distal clavicle resection has provided good results. Distal clavicle osteolysis is a unique disease most likely due to an overuse phenomenon. | | Language | eng | | Pub Type(s) | Journal Article
