Traumatic anterior hip dislocation is quite rare and accounts for 7% to 15% of all hip dislocations. Approximately 70% of anterior hip dislocations are the obturator type and represent less than 7% of all hip dislocations. Indentation fracture of the femoral head complicates 35-55% of obturator dislocations. Features of osteonecrosis of the femoral head and osteoarthritis of the hip joint may manifest within 2 years. Our index patient is a 19-year-old female who had conservative treatment for right obturator dislocation with indentation fracture of the femoral head. She recovered fully and had no features of osteonecrosis or secondary arthritis at 2 years postinjury. The aim of this report is to highlight the role of conservative treatment in the management of obturator dislocation with indentation fracture of femoral head.
