FLEXOR DIGITORUM PROFUNDUS AVULSION WITH ASSOCIATED FRACTURE OF THE DISTAL PHALANX

Two unusual cases of flexor digitorum profundus avulsion with an assoc iated fracture of the distal phalanx are reported. In one case the inj ury consisted of avulsion of a large bone fragment from the distal pha lanx and an associated profundus avulsion from the fragment. The other case showed simultaneous shaft fracture of the distal phalanx with av ulsion of the profundus tendon, which could not be included in the exi sting classification of profundus injuries. The latter injury was misd iagnosed initially.
