Ankle Dislocation 101: Understanding Dislocated Ankles

April 20, 2023

Anatomy of the Ankle and its Ligaments

The ankle is a complex joint that connects the leg to the foot. It is made up of three bones: the tibia, fibula, and talus. The tibia and fibula are the two bones of the lower leg and the talus is the bone of the foot that sits between the tibia and fibula.

The ankle joint is supported by several ligaments that provide stability and allow for movement. These ligaments include:

Ligaments of the ankle

  • Anterior Talofibular Ligament (ATFL): This ligament runs from the front of the fibula to the ankle bone (talus) and helps to prevent the ankle from rolling over to the outside.
  • Calcaneofibular Ligament (CFL): This ligament runs from the fibula to the heel bone (calcaneus) and helps to prevent the ankle from rolling over to the outside.
  • Posterior Talofibular Ligament (PTFL): This ligament runs from the back of the fibula to the ankle bone (talus) and helps to prevent the ankle from rolling over to the inside.
  • Deltoid Ligament: This ligament runs from the inside of the ankle bone (talus) to the heel bone (calcaneus) and the inner part of the ankle joint.

In addition to the above-mentioned ligaments, there are also several tendons that attach muscles to the bones of the ankle. These tendons include the Achilles tendon, which attaches the calf muscle to the heel bone, and the peroneal tendons, which attach muscles in the lower leg to the outside of the ankle.

Injury to the Ligaments

Injuries to the ligaments of the ankle are common in sports and other physical activities. A sprained ankle occurs when one or more of these ligaments is stretched or torn. The severity of a sprained ankle can range from a mild stretch to a complete tear of one or more ligaments.

The most common ligament to be injured is the ATFL. Injuries to this ligament can occur when the foot is rolled over to the outside. Injuries to the CFL and PTFL are less common, but they can occur when the foot is rolled over to the inside.

Ankle sprains can be treated with rest, ice, and physical therapy. In some cases, a brace or cast may be needed to protect the ankle while it heals. Severe sprains may require surgery to repair or reconstruct the damaged ligament.

Causes and Risk Factors for Ankle Dislocation

An ankle dislocation occurs when the bones of the ankle joint are forced out of alignment. This type of injury is rare and can be caused by a traumatic event such as a car accident or a fall from a significant height.

Causes of Ankle Dislocation

  • Trauma: A traumatic event such as a car accident or a fall from a significant height can cause the bones of the ankle to be forced out of alignment.
  • Sports: Certain sports such as soccer, football, and basketball that involve sudden changes of direction or landing from a jump can increase the risk of ankle dislocation.
  • Medical conditions: Some medical conditions such as osteoarthritis, rheumatoid arthritis, and gout can increase the risk of ankle dislocation.

Risk Factors

  • Previous Ankle Injury: Individuals who have previously suffered an ankle injury, such as a sprain or a fracture, are at an increased risk of ankle dislocation.
  • Weak Ankle: Individuals who have weak ankles are at an increased risk of ankle dislocation, as the ligaments and muscles that support the ankle are not as strong.
  • Age: Elderly individuals are at an increased risk of ankle dislocation due to the natural deterioration of the bones and ligaments that occurs with age.

Prevention

To reduce the risk of ankle dislocation, it is important to:

  • Wear proper shoes and equipment when participating in sports and other physical activities.
  • Strengthen the muscles and ligaments of the ankle through exercises such as calf raises and ankle stretches.
  • Be aware of your surroundings and take steps to prevent falls, such as removing hazards from your home and being extra cautious when walking on slippery surfaces.

In conclusion, ankle dislocation is a rare but serious injury that can be caused by a traumatic event or certain medical conditions. Risk factors include previous ankle injury, weak ankle, and age. It is important to take steps to prevent ankle dislocation by wearing proper shoes, strengthening the muscles and ligaments of the ankle and being aware of your surroundings.

Symptoms and Diagnosis of a Dislocated Ankle

An ankle dislocation is a serious injury that occurs when the bones of the ankle joint are forced out of alignment. It can cause severe pain, swelling, and difficulty bearing weight on the affected ankle.

Symptoms of a Dislocated Ankle

  • Severe pain: The most obvious symptom of an ankle dislocation is severe pain in the ankle. This pain can be intense and may be accompanied by a burning sensation.
  • Swelling: Another symptom of an ankle dislocation is swelling in the ankle. This swelling can be significant and may cause the ankle to appear deformed.
  • Bruising: Bruising may occur in the ankle and surrounding areas.
  • Inability to bear weight: Individuals with a dislocated ankle may have difficulty bearing weight on the affected ankle.
  • Deformity: The ankle may appear deformed or out of place.

It is important to note that these symptoms may also be present in other types of ankle injuries, such as a sprain or a fracture. Therefore, it is important to seek medical attention in order to receive a proper diagnosis.

Diagnosis

A physical examination by a qualified medical professional, such as an orthopedic surgeon or an emergency room physician, is needed to diagnose a dislocated ankle. The doctor will examine the ankle, looking for signs of deformity and instability, and may order imaging tests such as an X-ray or an MRI to confirm the diagnosis.

In some cases, it may be necessary to reduce the dislocation, which is a procedure that involves manually moving the bones back into their proper alignment.

It is important to seek medical attention if you suspect that you have a dislocated ankle, as prompt treatment can help to minimize the risk of long-term complications.

Treatment Options for Dislocated Ankles

An ankle dislocation is a serious injury that requires prompt medical attention. The treatment options for a dislocated ankle will depend on the severity of the injury, as well as the individual’s overall health and medical history.

Non-surgical treatment

  • Reduction: Depending on the severity of the injury, it may be necessary to reduce the dislocation by manually moving the bones back into their proper alignment. This is typically done by an orthopedic surgeon or an emergency room physician.
  • Immobilization: Once the ankle has been reduced, it is typically immobilized in a splint or cast to keep the bones in the correct position while they heal.
  • Pain management: Medications such as ibuprofen and acetaminophen can help to manage the pain associated with a dislocated ankle.
  • Physical therapy: Physical therapy is typically started as soon as the pain and swelling have subsided. This will help to regain strength and flexibility in the ankle, and prevent stiffness.

Surgical Treatment

  • Open reduction and internal fixation: In some cases, surgery may be necessary to repair a dislocated ankle. This typically involves making an incision in the skin, reducing the dislocation and then using screws, plates, or pins to hold the bones in the correct position while they heal.
  • Arthroscopy: In some cases, a less invasive surgical option is to use arthroscopy to repair the ligaments.

Recovery

The recovery time for a dislocated ankle can vary depending on the severity of the injury, as well as the individual’s overall health and medical history. It typically takes several weeks to several months for the ankle to heal, and physical therapy is typically needed to regain strength and flexibility in the ankle.
