Abstract: Traumatic obturator hip dislocation is rare. It accounts for 6 to 10 % of traumatic hip dislocations. It occurs in the context of violent trauma to a hip in a favourable position. Classically, dislocation occurs when the impact is brought to the anteriomedial part of the knee while the hip is in flexion and the limb in abduction and external rotation. The diagnosis is evoked before a hip deformation in flexion abduction external rotation. Confirmation is made by imaging. We report the case of an unhelmeted motorcycle passenger who allegedly fell from his motorcycle and landed on the anteriomedial side of the knee. The pelvic X-ray showed an obturator dislocation of the left hip. Under general anaesthesia, the dislocation was reduced by performing hip flexion associated with axial traction and then internal rotation adduction. The limb was immobilized in a knee brace for 21 days, bearing allowed after 60 days. At 36 months follow-up, the functional and radiological results are satisfactory.
