Subcoracoid acromioclavicular dislocations are rarely seen injuries of the shoulder. We present a patient with multiple injuries and a subcoracoid acromioclavicular dislocation resulting from a falling injury. Physical examination revealed painful mechanical block at 90 degrees of abduction and swelling in the acromioclavicular region. Diagnosis was made with direct radiographs and computerized tomography. Treatment consisted of distal clavicular resection and coraco-clavicular reconstruction with the transfer of the coracoacromial ligament over the clavicle. The patient had a pain-free shoulder after two years and was capable of performing daily activities despite the presence of coracoclavicular ossification.
