Jersey finger type IV: a case report.

Avulsion of the flexor digitorum profundus, usually known as jersey or rugby finger, is a rare condition that can only be treated surgically. It is mostly reported in sports injuries, in which the diagnosis is easily made. It is less frequent in household accidents, but should not be ignored because good results are time-dependent. Type IV jersey finger is the combination a fracture of the volar base of the distal phalanx and avulsion of the flexor digitorum profundus. This is a rare variety, and the surgical approach has not been discussed in detail. We introduce here a case report describing the clinical aspect, diagnostic approach, surgical technique and results at 6 months.
