Fracture-dislocations of the carpometacarpal (CMC) joints are pretty uncommon injuries with an incidence of 1%. A 17-year-old male was referred due to multiple traumas following a car accident with Glasgow Coma Score of 9.

Case Report:

Simultaneous metacarpophalangeal dislocation and CMC fracture-dislocation of the ring finger were present in the 4th finger (ring finger) of the right hand. Closed reduction and short arm splint in the intrinsic plus position was applied, and full range of motion was accomplished after 1 year postoperatively.


High clinical suspicion with adequate plain radiographs are required to diagnose precisely CMC fracture-dislocation injuries. To the best of our knowledge, any case report similar to the nature of the present injury has yet to be reported to date, addressing CMC fracture-dislocation of the ring finger and concomitant volar MCP joint dislocation in the same finger. Therefore, we can make the argument that our case report is unique.
