title: [Intra-articular block of the metacarpophalangeal joint of the index finger].
abstract: A case of rare intraarticular block of the metacarpophalangeal joint of the index finger is described. This block occurs exclusively in the metacarpophalangeal joint of the index finger in young persons as a result of trauma which forces the joint into severe flexion and strong ulnar deviation while maintaining normal articular relationship.
