Coronal Hamate Fracture Associated With Carpometacarpal Dislocations of All of the Fingers: Review of the Literature and Case Report

摘要

>Background: Dislocation of all 5 carpometacarpal (CMC) joints of a single hand is a rare injury. >Methods: The literature regarding CMC fracture-dislocations was reviewed and a case was presented. >Results: The relevant literature was consolidated to clinically relevant categories including ‘Clinical Presentation and Diagnosis,’ ‘Management of CMC Fracture Dislocation and Hamate Fractures,’ and ‘Outcomes.’ >Conclusions: The mechanism associated with this injury is often high energy that causes multiple simultaneous life- or limb-threatening injuries that could distract the examiner from identifying this injury. The case we present involves an axial dislocation of the carpus that resulted in dorsal dislocations of all CMC joints, dislocation of the hamate-capitate articulation, as well as fractures of the first metacarpal and the hamate.
