Hip dislocation
About Hip dislocation
A hip dislocation occurs when the upper part of the thigh bone (femur) comes out of it's normal location in a cup-like part of the pelvis called the acetabulum. Normally, the top of the femur rotates freely within this cup and forms a ball and socket joint. When the top of the femur comes out of the cup, the joint can no longer move freely and there is the potential for decreased blood flow to the femur. Dislocations may be the result of trauma such as an automobile accident. However, individuals who have had a hip replacement are at risk to experience dislocations without trauma, such deep squats and extreme rotation of the hip. A hip dislocation is a medical emergency and immediate medical attention is required. Ideally, the hip should be placed back in it's socket within six hours to avoid blood floor injury to the femur (avascular necrosis).Symptoms
Pain, upper leg deformity, inability to move leg, leg swelling, numbness, tenderness.Tests & Diagnostics
A history and physical will be performed. The diagnosis is usually confirmed with a x-ray. Additional imaging may be necessary pending the extent of the injury or for repeat dislocations with a MRI, CT scan.Common tests: CT Scan, MRI, X-ray.
OTC sleep aids and supportive treatments
Prescription medications
Conventional treatment summary
Treatment involves replacement of the top of the femur back in it's socket (reduction). This can usually be accomplished in the emergency room, but occasionally requires reduction in the operating room. Medications are given to control pain and provide sedation. The practitioner will then attempt to reduce the dislocation. Weight-bearing and range of motion may be restricted following the closed reduction.Medical specialties
