Coracoclavicular joint degeneration, an unusual cause of painful shoulder : A case report

A case of painful shoulder in a 42-year old righthand dominant Caucasian female due to degeneration of the coracoclavicular joint is described. The pain was aggravated by weight lifting. The diagnosis was confirmed radiographically with simple plain films and clinically by the injection of local anaesthetic (xylocaine 2%) that lead to the exclusion of any other concomitant pathology of the acromio-clavicular joint and the anterior subacromial space. The patient was treated successfully with an intra-articular steroid injection, and 30 months later she remains free of symptoms.
