Anteroinferior Tibiofibular Ligament Injury: Not Just Another Ankle Sprain

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanics

Background:

• Ankle sprains are common injuries.
• Injuries to the anteroinferior tibiofibular ligament (AITFL) are considered less frequent.
• Recent clinical observations suggest an increase in AITFL sprains.

Purpose of the Study:

• To describe the clinical presentation and management of ankle sprains involving the AITFL.
• To highlight the typical mechanism of injury and rehabilitation challenges associated with these specific sprains.

Main Methods:

• Retrospective review of patient cases with AITFL sprains.
• Clinical examination and diagnostic assessment.
• Analysis of injury mechanisms, symptoms, and treatment outcomes.

Main Results:

• AITFL sprains are often caused by forced external rotation of the tibia with the foot in dorsiflexion.
• Patients typically present with pain and tenderness over the distal anterior tibiofibular syndesmosis.
• Associated edema and ecchymosis are often minimal.
• Pain and disability can persist for several weeks, with rehabilitation requiring extended periods.

Conclusions:

• Ankle sprains primarily involving the AITFL, or high ankle sprains, require specific attention due to their potential for prolonged recovery.
• Understanding the mechanism of injury and providing appropriate, progressive rehabilitation are key to managing these injuries effectively.
