[Exposed distal radio-ulnar dislocation by dog bite. Reconstructive surgical technique using a soft tissue graft and a syndesmotic fixation implant. Case report].

The main function of the forearm is the supination, which is achieved largely through the biomechanical characteristics and stability of the distal radio-ulnar joint. There are several surgical techniques for the treatment of distal radio-ulnar dislocations isolated or associated with a fracture. We report the case of a canine trainer who was bitten at the wrist and distal forearm that came to the emergency department in where distal ulnar dislocation with muscle tendon exposure was diagnosed. Due to the offending agent and multiple soft tissue injuries the treatment with standard techniques was impossible. We describe the technique of treatment of this patient by placing autologous gracilis tendon graft, platelet rich plasma and two anchoring systems for ankle syndesmosis. Immobilization was maintained for six weeks with a subsequent rehabilitation and posterior valuation at 12, 18 and 28 weeks by the scale of MAYO, PRWE and DASH and finding a good result which implies the return to work and daily activities of the patient with minimal pain and limitation.
