Types of ankle injuries

Ankle injuries are not only painful but can also be incapacitating, affecting mobility and overall quality of life. Understanding the various types of ankle injuries is crucial for prompt diagnosis and appropriate treatment. Here's a list of the different classifications:


An ankle sprain occurs when the ligaments, which are the tough bands of tissue connecting bones in the joint, are stretched beyond their normal range of motion. There are three grades of sprains:

  • Grade 1 (Mild): This type involves slight stretching or minimal tearing of the ligament fibers. Symptoms typically include mild swelling and tenderness around the affected area.
  • Grade 2 (Moderate): In a moderate sprain, there is a partial tear in the ligament. This results in more significant pain, swelling, and difficulty bearing weight on the affected ankle.
  • Grade 3 (Severe): Severe sprains involve a complete tear or rupture of the ligament. This can lead to instability in the ankle joint, severe pain, swelling, and difficulty walking or standing.


Ankle fractures refer to breaks in one or more of the bones that make up the ankle joint, including the tibia, fibula, and talus. A broken bone in the ankle or an ankle fracture can occur due to sudden trauma, such as a fall or twist, or as a result of repetitive stress over time.

Tendon injuries

Tendons are tough, fibrous tissues that connect muscles to bones and help stabilize joints. Ankle tendon injuries can encompass various conditions, including:

  • Tendinitis: Inflammation of the tendon, often caused by overuse, excessive strain, or repetitive motion. Common symptoms include pain, swelling, and stiffness around the affected tendon.
  • Tendinosis: Characterized by degeneration and microscopic tears within the tendon, tendinosis can develop over time due to chronic overuse or inadequate rest and recovery.
  • Tendon Rupture: A complete tear or rupture of the tendon, which can occur suddenly due to a forceful impact or as a result of chronic degeneration. This typically causes severe pain, weakness, and difficulty moving the affected ankle.
  • Subluxation: Occurs when a tendon slips out of its normal position or groove, often resulting from trauma, repetitive stress, or anatomical abnormalities. Subluxation can cause pain, instability, and dysfunction in the ankle joint.

Common symptoms of ankle injuries

Identifying the symptoms of an ankle injury is crucial for prompt diagnosis and appropriate treatment. Whether caused by sudden trauma or overuse, ankle injuries can manifest in various ways, each carrying its own set of discomforts. Below are some common symptoms associated with ankle injuries:

  • Pain: Ankle pain is often the first indication of an injury. The intensity of pain can vary depending on the nature and severity of the injury. It may range from mild discomfort to sharp, debilitating pain, affecting mobility and daily activities.
  • Swelling: Swelling around the ankle joint is a prevalent symptom of injury. The affected area may appear visibly swollen, feel tender to the touch, and exhibit a sensation of warmth.
  • Bruising: The appearance of bruises or contusions on the skin around the ankle is another common symptom of injury. The discoloration may vary from mild to severe, depending on the extent of tissue damage.
  • Limited range of motion: Ankle injuries often restrict the joint's range of motion. The patient may experience difficulty performing movements such as walking, bending the ankle, or rotating the foot. Stiffness and tightness in the ankle area are also common manifestations.
  • Tenderness: Tenderness at the injury site is frequently observed in ankle injuries. The affected area may be sensitive to touch, and pressing on it may elicit pain.
  • Instability: Damage to the ligaments, such as in a sprain, can result in a feeling of ankle instability. Individuals may perceive the ankle as "giving way" or feeling unsteady during weight-bearing activities.
  • Difficulty bearing weight: Ankle injuries often make bearing weight on the affected foot challenging. Walking, standing, or putting pressure on the injured ankle can exacerbate pain and discomfort.
  • Crepitus: Crepitus, characterized by a crackling or popping sensation with ankle movement, can indicate underlying bone or cartilage damage.

Risk factors and causes of ankle injuries

Ankle injuries can occur due to various factors, ranging from participation in physical activities to individual anatomical characteristics. Knowing these risk factors and causes is essential for injury prevention and effective management. Here's a list of some of them:

  • Sports participation: Engaging in sports involving dynamic movements such as jumping, cutting, or sudden changes in direction significantly increases the risk of ankle injuries. Additionally, playing on uneven surfaces during sports or recreational activities heightens the risk of ankle sprains and fractures.
  • Previous ankle injury: Individuals with a history of chronic ankle instability, poorly rehabilitated ankle injuries, or chronic ankle sprains are at heightened risk of experiencing recurrent ankle problems. Inadequate healing and rehabilitation following an initial injury can compromise the stability and strength of the ankle joint, predisposing it to future injuries.
  • Anatomical factors: Certain anatomical characteristics, anomalies, or abnormalities can influence an individual's susceptibility to ankle injuries. Factors such as inadequate strength and stability in the ankle joint, extreme flexibility, and poor balance can increase the risk of ankle sprains, strains, and other traumatic injuries.
  • Sudden movements and trauma: Ankle injuries often occur due to sudden movements, traumatic incidents, or accidents. Common mechanisms of injury include tripping, falling, landing awkwardly after a jump, or twisting, rolling, or rotating the ankle during physical activities can place excessive stress on the ankle joint.
  • Age: Advancing age is associated with changes in bone density, joint integrity, and overall musculoskeletal health, which can contribute to an increased risk of ankle injuries. Older individuals may experience reduced bone strength and joint stability, making them more susceptible to fractures, sprains, and other ankle-related problems.

How healthcare professionals assess and diagnose ankle injuries

Assessing and diagnosing ankle injuries requires a methodical approach to clinical examination to ensure accurate evaluation and appropriate treatment. Healthcare professionals follow a general systematic process encompassing various steps:

Step one. Initial assessment

An initial assessment begins with a primary survey using the 'ABCDE' principles of resuscitation and trauma care. The healthcare practitioner will ensure the patient's airway, breathing, circulation, disability, and exposure are assessed and managed accordingly.

Afterward, the healthcare practitioner will look for any obvious deformities, open wounds, or signs of severe trauma, then assess the neurovascular status of the affected ankle, checking for pulses, sensation, and motor function.

Step two. History taking

The healthcare practitioner will then inquire about the mechanism of injury, including any twisting, impact, or sudden movements that occurred. They will also ask about the onset and duration of symptoms, including pain, swelling, and difficulty bearing weight. Finally, they must obtain a comprehensive medical history, including any previous ankle injuries, chronic conditions, or relevant medications.

Step three. Physical examination

After gathering information about the injury, the healthcare practitioner will thoroughly examine the injured ankle. A physical examination will typically includes the following:

  • Assessment of signs of swelling, bruising, redness, or deformity
  • Palpation of the ankle joint and surrounding structures to identify areas of tenderness and pinpoint the injury site.
  • Evaluation of the ankle's range of motion, including dorsiflexion, plantarflexion, inversion, and eversion.

During this step, the practitioner may also conduct specific tests to assess ligament stability and integrity, test muscle strength and function through resisted movements and manual muscle testing, and compare findings with the uninjured ankle to detect asymmetry and abnormalities. Aside from those, any signs of instability will also be noted.

Step four. Imaging tests

To confirm the diagnosis and assess the extent of the injury, the healthcare practitioner may consider ordering imaging tests. Two examples of such imaging tests are:

  • X-rays which are commonly used to evaluate for fractures, dislocations, or bony abnormalities.
  • Magnetic resonance imaging (MRI) scans for more detailed images of soft tissues, including ligaments, tendons, and cartilage.

How are ankle injuries treated?

Ankle injuries can significantly impact mobility and quality of life, but timely and appropriate treatment can facilitate recovery and prevent long-term complications. Here are examples of different ways to manage ankle injuries effectively:

  • Rest and immobilization: This includes using crutches or a walking aid to offload weight from the affected ankle and immobilizing the ankle. It may also be using a supportive brace or cast to stabilize the joint. In general, the patient is also encouraged to avoid weight-bearing activities to prevent further damage to the injured angle.
  • Ice therapy: Ice helps alleviate pain and reduce swelling by constricting blood vessels and minimizing inflammation.
  • Compression: To decrease swelling, the patient will be asked to wrap the ankle with an elastic bandage that provides gentle compression.
  • Elevation: The patient will elevate the ankle to reduce swelling and promote fluid drainage from the affected area.
  • Pain management: Over-the-counter pain relievers like ibuprofen (Advil), acetaminophen (Tylenol), or other prescribed medications can help alleviate pain and inflammation.
  • Physical therapy: Engaging in a comprehensive physical therapy program can restore an ankle's range of motion, strength, and stability.
  • Surgical intervention: In cases of severe ankle injuries, surgical intervention may be necessary to realign and stabilize the bones for proper healing, alleviating pain, and restoring function
