Traumatic Dorsoradial Trapezium-Metacarpal Joint Dislocation

A trapezium-metacarpal joint dislocation is a rare pathology reported in <1% of all hand injuries. Due to the rarity of this type of injury, no clear standard of treatment exists. Various treatment approaches are reported in the relevant literature, mainly consisting of anterior and posterior dislocation of the trapezium-metacarpal joint. In this case, a 38-year-old patient was treated for dorsoradial trapezium-metacarpal joint dislocation through open reduction with ligamentous reconstruction. Gradual improvement of the patient’s thumb mobility was observed following several physiotherapy sessions.
