Abstract

Background: Locking of the metacarpophalangeal (MP) joint of the thumb is a rare condition caused by hyperextension injury. Cases are treated by closed reduction, but open reduction is occasionally required.

Case presentation: Herein, we report a recurrent case of locking of the MP joint. Closed reduction was successful for treatment of the first injury but unsuccessful for the second injury, and open reduction was performed. At the operation for the second injury, we observed a transverse groove on joint cartilage of the metacarpal head.

Conclusion: In recurrent cases, we should assume the possibility of failure of closed reduction and prepare for open reduction.

Keywords: Open reduction; Thumb locking; Thumb metacarpophalangeal joint.
