A dislocated hip is an orthopaedic emergency that requires immediate diagnosis, evaluation, and treatment. It occurs when a great amount of force pushes the head of the thighbone (femur) out of its socket into the hip bone (pelvis). In approximately 90% of cases, the thighbone is pushed out of its socket in a backwards direction (posterior dislocation). The hip then becomes bent and twisted toward the middle of the body. Hip dislocations most commonly occur from motor vehicle accidents and falls from a height. They can also be a complication of hip replacement surgery.
Diagnostic procedures may include the following:
x-ray, MRI, CT scan
inability to move one leg
no feeling in the foot or ankle (a result of nerve damage)
The first step is usually to try and reposition the hip joint by applying force to the leg without surgery. Called a closed reduction of the hip replacement, it is performed under anesthesia.
If the dislocation occurs with additional damage such as a fracture, or involves a hip implant, an open reduction surgery may be needed. In this procedure surgeons must go in and manipulate the femur and hip and/or reposition the implants.
