Complete dislocation of the thumb metacarpal with extreme displacement

Abstract

This study reports a rare case of complete dislocation of the thumb metacarpal with extreme displacement. Although there are several reported cases of similar injury in earlier published reports, metacarpals of all the cases remained in situ. In this case, the metacarpal was totally displaced out of the hand. Although open reduction and internal fixation were performed, the clinical outcome was unsatisfactory because of severe soft tissue damage.
