Hip Dislocation

A Hip Dfislocation occurs when the ball of the thighbone (femur) is moved out of its place within the socket of the pelvic bone (acetabulum). This ball and socket structure forms the hip joint.

Causes

Hip Dislocations are relatively rare injuries. A normal hip joint is stable and strong. A hip dislocation can only occur when a strong force is applied to the hip joint. This can occur with:

Severe falls, especially from heights
Motor vehicle accidents, including motorcycles
Sports injuries

Risk Factors

A risk factor is something that increases your chance of getting a disease, condition or injury.

Prior hip replacement surgery
Abnormal hip joint
Alcohol use
Hip fracture

Symptoms

Symptoms include:

Severe pain in the hip, especially when moving the leg
Leg on the affected side appears shorter than the other leg
Hip joint appears deformed

Diagnosis

The doctor will ask about your symptoms and how the injury occurred, and examine your hip and leg. Tests may include: X-ray – a test that uses radiation to take a picture of structures inside the body, especially bones CT Scan – a type of x-ray that uses a computer to make pictures of structures inside the body

Treatment

Treatments include:
Closed Reduction
The doctor will manipulate the thigh and hip joint, in an attempt to put the ball of the femur back into the hip socket. Medications to keep you relaxed during this procedure may include:

Pain medication
Sedation
Muscle relaxants
General or spinal anesthesia

Open Reduction
If closed reduction is unsuccessful, surgery may be performed to put the ball back into the hip socket. Open reduction is often necessary if the thigh or pelvic bones are broken, as well.

Prevention

There are no guidelines for preventing Hip Dislocation. To reduce your risk of hip dislocation and other serious injuries:

Wear your seatbelt in the car.
Obey speed limits and other traffic laws.
Do not drink and drive.
Wear all recommended safety equipment when participating in recreational or athletic activities.
