Hip dislocations account for 2–5% of total hip dislocations, and they can be posterior or anterior. Major complications of traumatic hip dislocation include avascular necrosis of femoral head, secondary osteoarthritis, sciatic nerve injury and heterotopic ossification. F ootball is one of the most popular sports in the world. Injuries during a football game are quite frequent, but in the majority of them are contusions, sprains and/ or strains in the thigh, knee and ankle [8]. On the other hand, fractures during the game are quite rare ranging from 4 to 9%, while the probability of a fracture-dislocation of the hip is extremely rare [9]. Hip dislocations during sporting activities account for 2–5% of total hip dislocations [2], and they can be posterior or anterior. Most hip dislocations are posterior, caused by impaction of the femoral head upon the acetabulum from direct force to the distal femur. Anterior dislocations are less common and of two main types: superior, where the femoral head is displaced into the iliac or pubic region, and inferior, where the head lies in the obturator region [4]. Motivated by the case of a 33-year-old football player, who suffered a posterior hip dislocation while playing football, we will review the literature. Case Presentation A 33-year-old male was brought to the emergency department with right hip pain, weakness and inability to walk. The patient was injured during a football game while falling on his knee with his hip flexed. At the time of the injury the patient felt a pop and immediately after he could not move his hip. Clinical examination of the injured extremity suggested posterior dislocation of the hip. The hip was flexed, adducted and internally rotated. Neurological evaluation was normal with no signs of sciatic nerve injury. Plain radiographs of the pelvis confirmed a posterior hip dislocation, associated with a posterior wall fracture of the acetabulum (Fig. 1). Within 6 hours past the injury, and 16
