Metacarpophalangeal (MCP) joint dislocations are uncommon injuries. Most dislocations occur dorsally, with volar dislocations being rarer owing to the architecture of the joint. Because of the rarity of the condition, there is no accepted standard treatment for these injuries. The most commonly affected digit is the ring finger, followed by the middle finger and then the small finger. Management depends on the complexity of the injury, with complex dislocations requiring open reduction owing to interposed soft tissue and repair of damaged ligaments and tendons. We describe a 52-year-old man with chronic MCP dislocation who underwent unsuccessful open reduction and subsequently required joint arthroplasty.
