Radio carpal dislocation is rare, its frequency is 0.2%. The pure form is an exceptional entity. We provide a typical observation of this lesion. 32 years old patient, victim of a road traffic accident, admitted to the emergency. The examination of the left arm objectified a cross wound next to the palm side of the left wrist (A), the neuro vascular examination shows no damage. Radiography’s front and profile views of the left wrist, showed a pure left posterior radio carpal dislocation (B). The patient was operated 2 hours after the trauma, under locoregional anesthesia. After the reduction of the radiocarpal dislocation, the patient received a plug-lunar radio and radio-scaphoid then a transverse racking radio-ulnar . The radiography of control confirmed the reduction of the dislocation (C, D). The patient underwent wrist immobilization for 6 weeks, followed by a pin ablation (E) then sessions of reeducation. After a backward movement of 18 months, the evolution was good, with a normal mobility of the wrist.Keywords: Dislocation, pure, radio carpalPan African Medical Journal 2016; 2
