Introduction: Traumatic dislocation of the coxofemoral joint is defined as the permanent posterior or anterior displacement of the femoral head out of the acetabular cavity. It is generally the consequence of a violent trauma, most often an accident on the public road. Our case it is a post-traumatic hip obturator dislocation, managed in our department. Clinical case and results: 16 years old patient, with no particular history, victim of a fall from his motorcycle during a race, causing a closed trauma to his left hip, right ankle and left wrist. He comes with a vicious attitude: left lower limb in flexion, abduction, external rotation. An X-ray requested objective obturator dislocation with a small bone fragment of the head. A bone reconstruction CT was completed in favour of obturator dislocation with head fracture type 1 according to Pipkin's classification. Patient sent directly to the block, he benefits from a reduction under sedation according to Boehler's maneuver, control by scopy, then immoblisation by zimmer splint after testing the stability of dislocation. Patient is hospitalized in our ward for monitoring then follow-up in consultation. Results were satisfactory, removal of the zimmer splint at the 6th week. Total support was possible at week 12, with complete mobility, patient reviewed afterworld without clinico-radiological signs of aseptic necrosis of the femoral-head. Conclusion: Obturator dislocation remains rare, especially in sports, diagnosis and early reduction is essential for good progress. However, we should not to ignore the associated fracture which still darkens the prognosis.
