Traumatic Anterior Hip Dislocation in Elderly Male: An Atypical Case Report.

Introduction: Anterior dislocation of the hip joint is a rare presentation accounting for around 15% of all hip dislocations. Obturator (inferior) type traumatic anterior hip dislocation in adult is rare of all types of hip dislocation. Here, we described a case with same description. It can occur as a result of a high-energy trauma in circumstances such as a motor vehicle accident or a fall from a significant height. A delay in relocation of more than 6 h has been associated with a high risk of avascular necrosis of the femoral head.

Case Report: We reported the case of a 70-year-old man who suffered an anterior dislocation of his hip joint who was brought to the emergency room with a history of fall from the bicycle hit by a motorcyclist from his back. After examined clinically and radiologically, the patient was diagnosed with obturator type of anterior right hip dislocation. Closed reduction under short general anesthesia was planned.

Conclusion: Inferior hip dislocations are very rarely seen injuries with severe high-energy trauma. The reduction must be done as soon as possible because it involves the functional prognosis of the hip by the risk of necrosis of the femoral head and subsequent osteoarthritis requiring long-term monitoring.
