Flexor digitorum profundus avulsion through enchondroma

A flexor digitorum profundus tendon avulsion occurring at the site of a pathological fracture through an enchondroma is reported. The avulsion appears to be the result of direct trauma crush to the distal phalanx of the little finger. The lesion was curetted and grafted using autogenous bone, the fracture was stabilized with a K-wire and the tendon was advanced and secured using Bunnell pullout wire technique. The lesion healed and function was restored.
