Fracture Avulsion of the Flexor Digitorum Profundus Tendon: A Case Report

In this report, we present a schematic case of deep flexor tendon avulsion of the fourth finger of the left hand. The lesion consists of an intra-articular fracture of the distal palmar portion of the distal phalanx of the fourth finger, resulting in a large bone fragment, which remains incarcerated at the A4 pulley. The diagnosis was retained preoperatively; re-insertion by “pull out” followed by functional re-education allowed complete functional restoration after 4 months of trauma.
