dislocation

Condition Uncommon
Description
Dislocation is a condition in which a bone has come out of place from a joint, usually due to a sports injury, a fall, a bike/car accident, or a birth defect. The dislocated joint can have its out-of-place bone put back into proper position, but further treatment may be needed to help prevent recurrences.

What are dislocations?

Joint displacement.

Dislocations
A dislocation of a joint occurs when the 2 matching surfaces of a joint are no longer in contact. This is typically quite painful and requires immediate medical attention. The joint will need to be reduced, in order for the 2 joint surfaces to come together. This often requires some form of anesthesia or sedation. After a dislocation, the joint may be unstable and require immobilization.

Whats a patella dislocation?

Knee cap

Patella
A patella dislocation is when the knee cap comes out of place. This generally occurs towards the outside of the knee and can occur with twisting injuries to the knee. The medial patellofemoral ligament is often injured and there can be injuries to the cartilage inside the knee. As long as there are no cartilage injuries and it is the initial dislocation, they typically respond well to therapy

What causes jaw dislocations?

Many reasons

Malocclusion
A malocclusion, opening too wide, grinding your teeth, chewing too much gum, having oral surgery done can cause dislocation of the tmj. Any one or more of the above situations will do it. These are the most common causes, there are plenty of others.

Dr. Jeffrey Sider answered:

Is patellar dislocation curable?

It's curable

Dislocations
If you really have a history of patella dislocation, it is something that may be successfully treated with physical therapy, but it may require a surgical procedure to help realign the patella. It is important to have an orthopedic exam and possibly an mri to differentiate a subluxation problem from a dislocation

How is a hip dislocation treated?

Put back in place

Dislocations
Any dislocated joint needs to be put back in place ASAP! Once reduced a stable joint needs early protected range of motion and an unstable joint needs immobilization. The hip joint is a special case. Dislocation of the hip interrupts the blood supply to the femoral head, which may lead to osteonecrosis (bone death). See a board certified Orthopaedic surgeon who specializes in trauma for treatment.

Dr. Jeffrey Sider answered:

How can I treat patellar dislocation?

Reduce it

Dislocations
Obviously the initial treatment for any patella dislocation is to replace the patella into proper position. The leg should then be immobilized to allow healing and to allow swelling to subside. Then one must evaluate the knee and determine if this is a onetime traumatic event or a recurrent problem which might require either physical therapy or a surgical procedure.

What is done for a kneecap dislocation?

Depends on frequency

Dislocations
Single episode of dislocation treated non-op with therapy and selective muscle strengthening/retraining, sometimes bracing/taping. Recurrent episodes suggest anatomic predisposition to instability and warrant consideration for operative stabilization. Most important static stabilizer of kneecap(patella) is medial patellofemoral ligament and is frequently reconstructed for recurrent dislocations.
