Rehabilitation of a dislocated elbow involves restoring the joint's range of motion, strength, and stability. Here are some steps that can be followed:

1. Medical evaluation: A medical professional should evaluate the elbow to ensure there are no other injuries or complications that require further treatment.

2. Immobilization: The elbow will need to be immobilized for a period of time, typically a few weeks, using a brace or cast to allow the ligaments and soft tissues to heal.

3. Ice and elevation: Applying ice to the elbow and elevating it can help reduce swelling and pain.

4. Pain management: Pain medication may be prescribed to manage discomfort during the recovery period.

5. Range of motion exercises: After the elbow has healed sufficiently, gentle range of motion exercises can be started. This will help restore flexibility and reduce stiffness in the joint.

6. Strengthening exercises: As the range of motion improves, strengthening exercises can be added to rebuild muscle strength in the elbow and surrounding muscles.

7. Gradual return to activity: It is important to gradually return to normal activities and sports to avoid re-injury.

It is essential to follow a medical professional's instructions carefully during rehabilitation and to avoid putting too much strain on the elbow before it is fully healed.
