Dislocation of all (first through fifth) carpometacarpal joints

Discussion:

An interesting rare case of (ALL) 1st through to the 5th carpo-metacarpal joint dorsal dislocation. 

Carpo-metacarpal joint dorsal dislocation usually occurs when the hand is forcibly palmar flexed.

Most dislocations are accompanied by fractures of either the involved metacarpals, carpals, or both secondary to the force which causes this type of dislocations.

These type of injuries can be missed secondary to the extensive swelling and edema of the hand.

Lateral radiograph is accurate diagnose this type of injury.
