What Is an Ankle Sprain?
An ankle sprain is an injury to one or more ligaments in the ankle, usually on the outside of the ankle. Ligaments are bands of tissue – like rubber bands – that connect one bone to another and bind the joints together. In the ankle joint, ligaments provide stability by limiting side-to-side movement.
Some ankle sprains are much worse than others. The severity of an ankle sprain depends on whether the ligament is stretched, partially torn, or completely torn, as well as on the number of ligaments involved. Ankle sprains are not the same as strains, which affect muscles rather than ligaments.
The symptoms of ankle sprains may include:
- Pain or soreness
- Difficulty walking
- Stiffness in the joint
What Is an Ankle Fracture?
A fracture is a partial or complete break in a bone. Fractures in the ankle can range from the less serious avulsion injuries (small pieces of bone that have been pulled off) to severe shattering-type breaks of the tibia, fibula, or both.
Ankle fractures are common injuries that are most often caused by the ankle rolling inward or outward. Many people mistake an ankle fracture for an ankle sprain, but they are quite different and therefore require an accurate and early diagnosis. They sometimes occur simultaneously.
An ankle fracture is accompanied by one or all of these symptoms:
- Pain at the site of the fracture, which in some cases can extend from the foot to the knee
- Significant swelling, which may occur along the length of the leg or may be more localized
- Blisters may occur over the fracture site. These should be promptly treated by a foot and ankle surgeon.
- Bruising that develops soon after the injury
- Inability to walk—however, it is possible to walk with less severe breaks, so never rely on walking as a test of whether a bone has been fractured
- Change in the appearance of the ankle – it will look different from the other ankle
- Bone protruding through the skin—a sign that immediate care is needed. Fractures that pierce the skin require immediate attention because they can lead to severe infection and prolonged recovery.
Chronic Ankle Instability
What Is Chronic Ankle Instability?
Chronic ankle instability is a condition characterized by a recurring “giving way” of the outer (lateral) side of the ankle. This condition often develops after repeated ankle sprains. Usually the “giving way” occurs while walking or doing other activities, but it can also happen when you’re just standing. Many athletes, as well as others, suffer from chronic ankle instability.
People with chronic ankle instability often complain of:
- A repeated turning of the ankle, especially on uneven surfaces or when participating in sports
- Persistent (chronic) discomfort and swelling
- Pain or tenderness
- The ankle feeling wobbly or unstable
Common Disorders of the Achilles Tendon
What Is the Achilles Tendon?
Achilles tendon is a band of tissue that connects a muscle to a bone. The Achilles tendon runs down the back of the lower leg and connects the calf muscle to the heel bone. Also called the “heel cord,” the Achilles tendon facilitates walking by helping to raise the heel off the ground.
Achilles Tendonitis and Achilles Tendonosis
Two common disorders that occur in the heel cord are Achilles tendonitis and Achilles tendonosis.
- Achilles tendonitisis an inflammation of the Achilles tendon. This inflammation is typically short-lived. Over time, if not resolved, the condition may progress to a degeneration of the tendon (Achilles tendonosis), in which the tendon loses its organized structure and is likely to develop microscopic tears. Sometimes the degeneration involves the site where the Achilles tendon attaches to the heel bone. In rare cases, chronic degeneration with or without pain may result in rupture of the tendon.
- a fall,
- a sudden twist, or
- a blow that forces the ankle joint out of its normal position.
- wearing inappropriate shoes, or
- walking or running on an uneven surface.
