Definition

An ankle dislocation occurs when the joint between the talus (foot) and tibia (shin) bones in the leg becomes separated. This injury often occurs along with an ankle fracture and happens when the stress applied to the ankle exceeds the strength of the ligaments that stabilize the joint.

Causes

Ankle dislocations typically happen due to severe trauma to the ankle. These injuries tear one or more ligaments, which are responsible for keeping the bones in place. As a result, the bones become dislocated. Common causes include motor vehicle accidents and sports-related injuries, especially those involving jumping. The most common instance of ankle dislocation occurs when the foot is in a tiptoe position and the person falls.

Risk Factor

Certain factors can increase your risk of experiencing an ankle dislocation, including:

• Frequent participation in athletic activities.

• A history of previous sprains, fractures, or dislocations.

• A pre-existing foot joint disorder.

• Conditions that loosen ligaments, such as Ehlers-Danlos syndrome (a genetic disorder affecting connective tissue).

• Smoking or obesity.

Symptoms

The following symptoms typically occur with a dislocated ankle joint:

• Intense pain immediately after the injury.

• Swelling and bruising around the ankle.

• Pain upon touching the injured area.

• Inability to bear weight on the affected leg.

• Difficulty moving the ankle joint.

• Deformity or abnormal appearance of the leg.

• The bone may appear to be pushing through the skin.

Diagnosis

To diagnose a dislocated ankle, your doctor will review your injury history and symptoms. They will conduct a physical examination of your foot, looking for signs of pain, swelling, and potential damage to nerves or blood vessels. You may be asked to move your toes or check for blood flow by pressing on your toes. If there is any indication of a bone fracture, especially if it is open (where the skin breaks), the doctor will order imaging tests such as an X-ray.

If there are concerns about nerve or blood vessel involvement, these issues will be addressed first. In some cases, a CT scan may be necessary, particularly if surgery is needed.

Management

For an ankle dislocation, you will typically be referred to an orthopedic specialist. The treatment plan depends on the location of the dislocation and whether other injuries are present. Common treatments include:

• Pain relief through medication.

• Non-surgical repositioning of the bone (reduction).

• Elevating the foot and applying ice to reduce swelling.

• Emergency surgery if necessary.

• A splint to immobilize the foot.

• A cast to hold the foot in position after the swelling decreases.

Surgery

If necessary, surgery will be performed to reposition the bones and allow proper healing. This process is called reduction, and the bones may be held in place using plates and screws through a technique known as internal fixation. Any ligament damage will also be repaired during the procedure.

Recovery

During the recovery process for an ankle dislocation, you may be prescribed medications to prevent blood clots and manage pain. If the injury caused any skin damage, antibiotics may be prescribed to prevent infection.

As healing progresses, a splint may be provided to help stabilize the ankle. Physical therapy will also play a key role in restoring function, improving mobility, and maintaining strength in the affected leg. Depending on the severity of the injury, you may need crutches or a cane for several months to assist with mobility. Your doctor or therapist will guide you on when it’s safe to return to your normal activities.

A proper diet rich in calcium, vitamin D, and protein can help support the healing process. Additionally, avoiding certain pain relievers may be advised, as they can interfere with bone healing. If you smoke, it is strongly recommended that you quit, as smoking can hinder the recovery of bone tissue.

Complications

Without proper treatment, complications from an ankle dislocation can occur, including:

• Nonunion or malunion (issues with the proper healing or alignment of the bone).

• Synostosis, the abnormal fusion of bones that shouldn’t be fused.

• Entrapment of tendons, the injury may affect tendons or surrounding structures, causing complications.

• Cartilage injuries.

• Fractures of the talus bone.

• The joint may become stiff and limit range of motion.

• Injury to blood vessels.

• Compartment syndrome, an increased pressure within the muscle compartment, which can be life-threatening if not treated immediately.

Prevention

While ankle dislocations are common in sports like running, tennis, and soccer, several steps can reduce the risk of injury:

• Warm-up Before Exercising

A proper warm-up, such as light jogging or stretching, prepares the muscles for more intense activity. Avoid overstretching or using jerking movements.

• Muscle-Building Exercises

Gradually increase physical activity to build strength and flexibility. Strengthening muscles around the ankle helps prevent injuries.

• Choose Suitable Shoes For Your Feet

Proper footwear is essential for preventing ankle injuries. Choose shoes that fit your foot type and provide stability. Athletic shoes should be replaced regularly, ideally every six months for regular runners.

• Avoid Running or Walking on Uneven Surface

Be cautious of obstacles like potholes, tree roots, or uneven surfaces. Practice on the same type of surface where you’ll be running to reduce the risk of injury.

When to See a Doctor?

Seek immediate medical attention if your symptoms worsen, or if you experience numbness, swelling, fever, or chills. You should go to the emergency room if you notice sudden, severe symptoms such as shortness of breath or excessive pain.
