The hip is a ball and socket joint, composed by the head of the femur/thighbone (ball) and the acetabulum in the pelvis (socket). Injuries to the hip can cause the ball to be removed from the socket.
What is hip dislocation?
A hip dislocation is when the ball of the hip joint moves from its natural position in the socket, usually because of trauma. Often other injuries occur alongside a hip dislocation, including fractures to the pelvis, legs, and back or injuries to the knee, head or abdominal area.
In people who have had hip replacement surgery, it’s possible that a fall or accident can cause the prosthetic to dislocate.
What are the symptoms of hip dislocation?
If you have a hip dislocation, you will experience a high level of pain and will not be able to move your leg.
You may also experience:
- Muscle spasms
- Numbness in the foot or ankle – if nerves have been damaged
- Abnormal positioning of the leg – turned inwards or outwards, depending on the type of dislocation
- One leg shorter than the other
What causes hip dislocation?
Hip dislocation is caused by trauma to the hip joint (e.g. a car accident, a fall from a high height or sports injuries).
In people who have had hip replacement surgery, it’s possible that a less serious fall can cause the prosthetic to dislocate.
How is hip dislocation diagnosed?
If you have any of the symptoms listed above and believe you have a dislocated hip, it is essential that you go to a consultant immediately.
Your consultant will perform a physical examination and send you for X-rays to determine whether you have hip dislocation.
How is hip dislocation treated?
Your consultant will attempt to put the ball back into the socket. This is a procedure known as a reduction, and will be done under sedation or anaesthetics.
If your consultant is unable to get the ball into the socket, you may undergo a CT scan to see whether there are bone fragments/other foreign objects that are inhibiting it from being put back in place.
You will likely need to undergo physiotherapy afterwards in order to regain strength in the affected hip.
