Extensor Hallucis Longus Contracture Following Intramedullary Nailing for a Pilon Fracture.

Extensor hallucis longus (EHL) fibrosis is an uncommon complication following a pilon fracture. This is caused by compartment syndrome from fracture immobilization followed by adhesion of muscle or tendon. Only a few cases of EHL fibrosis secondary to a post-traumatic lower leg fracture have been reported.
