Abstract
Locking of the metacarpophalangeal joint of the thumb following forced hyperextension is rare. Unlike the locking that occurs with metacarpophalangeal dislocation of the other fingers in flexion, it is locked in mild hyperextension at the metacarpophalangeal joint of the thumb, which can not be flexed actively. The main pathology is thought to be a constriction ring over the radial condyle of the metacarpal head, which is formed by a torn volar plate proximal to the radial sesamoid bone and radial accessory collateral ligament. Manual reduction is successful, if the dislocated ligament bundle is not too tight. If gentle manipulation fails, surgery is generally recommended to release the locking, that is, release of accessory collateral ligament. We present three cases of locking of the metacarpophalangeal joint of the thumb, which we treated successfully with closed reduction.
