Background: Dislocation of both ends of the clavicle is arare traumatic lesion and the mechanism of the lesionis usually related to major trauma. The first case wasdescribed in 1831.
Case Description: We present the oldest referenced caseof this alteration. The skeleton studied belonged to an oldwoman buried inside the Sant Pere de Madrona Church inBerga (Barcelona/Spain) and its dating indicated it corre-sponded to the end of the 17th century. There was apseudarthrosis between the clavicle and coracoid ligament;when the bones were reconstructed by pseudarthrosis bothends of the clavicle appeared dislocated.
Literature Review: Bipolar dislocation of both ends of theclavicle, or ‘‘floating-clavicle’’, is a rare injury. Since 1831when this type of injury was first reported, approximately40 cases have been published. No archaeological case hasbeen published.
Clinical Relevance: Despite experiencing bipolar dislo-cation of both ends of the clavicle, or floating-clavicle, it ispossible to have acceptable function of the arm as sug-gested by the anthropologic parameters analyzed here. Thehead of the humerus of the affected shoulder shows noabnormalities and the contralateral glenoid cavity showssevere osteochondritis of the anteroinferior side.
