The authors present a previously unreported case of an open fracture of the distal tibia and fibula with associated Achilles tendon rupture in a 27-year-old motorcyclist. Management followed established trauma principles of wound exploration, debridement, and stabilization of the fracture with reamed locked intramedullary nailing of the tibia. The injury to the Achilles tendon was not identified until surgical exploration for fixation of the fracture. This required a 2-stage operative approach, involving initial debridement and fracture fixation followed by Achilles tendon repair during the second-look wound review procedure. The authors believe this to be the first reported case of Achilles tendon rupture in association with an open transverse distal tibia fracture. Prior to surgical exploration of the wound, Achilles tendon rupture was not suspected, emphasizing the need for clinical suspicion, thorough examination, and adequate wound exploration at operation for fracture fixation.
