Dislocation of ankle joint can be caused by a high-impact force on the ankle such as a fall, twist, or direct blow to the joint. It can also be caused by a medical condition such as arthritis or a previous ankle injury.
Diagnosis of a dislocation of the ankle joint is typically made by a physical examination, which includes the doctor feeling the joint and assessing the range of motion and strength in the joint. X-rays may be taken to confirm the diagnosis.
Differential diagnosis includes fractures, sprains, and ligament tears.
Treatment for a dislocated ankle joint typically includes immobilization of the joint with a cast or splint, followed by physical therapy to restore range of motion and strength. Surgery may be necessary for severe cases to repair any damaged ligaments or tendons.
The prognosis for a dislocated ankle joint is generally good. Most patients are able to regain full strength and range of motion after treatment. However, some patients may have long-term instability or chronic pain in the joint.
