What is Ankle Dislocation?

Ankle dislocation is a condition that occurs when the bones of the lower leg called the fibula and tibia get separated from the talus or ankle bone. This can cause serious damage to the nerves and ligaments surrounding the ankle, leading to a decline in strength and overall health of the leg.

Causes of Ankle Dislocation

Some of the common causes of ankle dislocation include:

  • Motor vehicle accidents
  • Sports injury
  • Inward or outward rolling of the ankle
  • Severe falls
  • Sprain
  • Direct fall on the foot

Symptoms of Ankle Dislocation

The signs and symptoms of ankle dislocation include:

  • Severe pain
  • Instability
  • Ankle swelling and bruising
  • Stiffness and weakness
  • Limitations in the movement of the ankle


Your doctor will review your symptoms and medical history and perform a thorough physical examination to check for a range of motion and any damage to the ligaments, blood flow, and stability. The following diagnostic tests may be performed for further evaluation of the injured ankle.

  • X-rays: During this study, high electromagnetic energy beams are used to produce images of the bones.
  • CT scan: Special x-rays are used to produce images of any damage in the ankle.

Treatment for Ankle Dislocation

You will be instructed to apply an ice pack and keep your ankle in an elevated position to reduce swelling. Depending on your condition, your doctor will place the affected leg in a therapeutic brace to keep it stable and may prescribe medications to reduce pain and swelling. You may need surgery to repair any damaged ligaments, blood vessels, nerves, or any adjacent structures of the ankle.
