Severe pure open dislocation of the ankle and flexor digitorum longus tendon tear a case report

Proximal avulsion rupture of the flexor digitorum longus (FDL) tendon associated with an ankle dislocation is extremely rare. We report a case of a 29 years old patient presenting a severe open ankle dislocation with flexor digitorum longus tendon tear after a motorcycle accident. We performed wound debridement, ankle reduction, tendon repair and stabilization with external fixation. At our last follow-up 17 months after the operation, the patient had good functional outcome and returned to work. This report is noticeable as it is, to the best of our knowledge, the third study reporting a case with simultaneous open ankle dislocation and proximal avulsion rupture of the FDL tendon.
