title: Locked metacarpophalangeal joint of the little finger due to hyperextension injury: a case report.
abstract: We treated a rare case of locked metacarpophalangeal joint of the little finger due to a hyperextension injury. The mechanism of the occurrence was considered to be closely similar to those that happened in the thumb, and the locking was successfully released by a manual reduction without complication.
