High ankle sprain

High Ankle Sprain

A high ankle sprain, also known as a syndesmotic sprain, is an injury to the syndesmosis ligaments, which connect the two bones of the lower leg, the tibia and the fibula. This type of sprain is less common than the traditional ankle sprain, which affects the ligaments on the outer side of the ankle. High ankle sprains are often associated with sports and activities that involve twisting, cutting, or high-impact forces.

Causes

High ankle sprains occur when there is excessive force that spreads the tibia and fibula apart, damaging the syndesmosis ligament. This can happen through direct impact to the ankle or when the foot is planted and the body twists. Common causes include:

• Contact sports such as football, soccer, and rugby
• Skiing and snowboarding accidents
• Falls where the foot is in an awkward position

Symptoms

Symptoms of a high ankle sprain include:

• Pain above the ankle, especially when the foot is twisted or when bearing weight
• Swelling and bruising around the ankle and lower leg
• A feeling of instability in the ankle
• Difficulty walking or bearing weight on the affected leg

Diagnosis

Diagnosis of a high ankle sprain involves a physical examination and imaging tests. During the examination, a healthcare provider will assess pain, swelling, and range of motion. Imaging tests may include:

• X-rays to rule out a fracture
• MRI to assess the extent of ligament damage
• Ultrasound to evaluate ligament integrity

Treatment

Treatment for a high ankle sprain depends on the severity of the injury. Options include:

• Rest and avoidance of activities that cause pain
• Ice to reduce swelling
• Compression with a bandage to support the ankle
• Elevation of the leg to decrease swelling
• Physical therapy to restore range of motion and strength
• In severe cases, surgery may be required to repair the damaged ligaments

Recovery

Recovery time for a high ankle sprain varies depending on the severity of the injury. Mild sprains may heal within a few weeks, while more severe injuries can take several months. It is important to follow a healthcare provider's recommendations and not return to full activity too soon to prevent re-injury.

Prevention

Preventive measures for high ankle sprains include:

• Wearing appropriate footwear for activities
• Strengthening exercises for the muscles around the ankle
• Proper warm-up and stretching before exercise
• Avoiding activities that put unnecessary stress on the ankles
