Hip dislocation is usually a result of trauma that dislocates the ball from the socket – also referred to as hip luxation. In order for the hip to luxate the trauma must have been significant to rupture the capital ligament. The femur almost always luxates the same way; up and forward.
The most obvious symptom is when the patient is not bearing weight on the affected leg, however a radiograph will help confirm if the joint is dislocated. If the luxation is not corrected, scarring and fibrous attachments can create a false joint.
Repairing a Hip Luxation:
- The dislocation is repaired by closed reduction.
- This is means that the luxation is corrected by sliding the ball of the femur back into the socket manually without a surgical incision.
- If the hip appears to be normal other than the luxation and occurred within three days, this is the most common solution.
- If the injury happened longer than three days ago, muscle contraction makes successful reduction very challenging.
- Other complications, such as damage to the femoral head or pelvis, will require surgical repair.
- Surgical techniques vary and depend on damage.
- Optimally, the hip is able to be reduced and only a small tear in the joint capsule must be repaired with suture.
- In some cases, the joint capsule is too damaged, resulting in the need to places screws around the acetabulum, and a hole drilled to it keep the joint in place.
