Causes

Hip dislocations are relatively rare and severe injuries. They are often associated with femur or pelvic fractures . A normal hip joint is stable and strong. A hip dislocation can only occur when a strong force is applied to the hip joint.
  • Severe falls, especially from heights
  • Motor vehicle accidents
  • Sports injuries, especially from football, rugby, skiing, and snowboarding
 

Risk Factors

Factors that can increase your chance of developing this condition include:
  • Prior hip replacement surgery
  • Abnormal hip joint
  • Severe falls, especially from heights
  • Motor vehicle accidents
  • Sports injuries, especially from football, rugby, skiing, and snowboarding
  • High risk behaviors, such as excessive alcohol use
  • Poor muscle control or weakness leading to falls
 

Diagnosis

The doctor will ask about your symptoms and how the injury occurred. An exam of your your hip and leg will be done.
Images may be taken of your bones. This can be done with:
  • X-ray
  • Computed tomography (CT) scan —to look for loose bodies and fragments impeding reduction, and acetabular fractures
  • MRI—to evaluate ligament, cartilage and other soft-tissue injury
 

Treatment

Treatments include:

Open Reduction

In some cases, surgery is needed. Open reduction is often done if:
  • Closed reduction is unsuccessful
  • Bony fragments or soft tissue remain in the joint space
  • The joint remains unstable
  • The thigh or pelvic bones are also broken

Physical Activity

When you are ready, you should begin range of motion exercises to keep your hip joint flexible as recommended by your doctor.
Your doctor will refer you to a physical therapist to help you with your rehabilitation.
