Magnetic Resonance Imaging Evaluation of Lateral Ankle Instability

Magnetic Resonance Imaging Evaluation of Lateral Ankle Instability

Lateral ankle instability may be acute or chronic. Acute instability usually occurs due to extreme rear foot supination with planter-flexion trauma leads to injury of lateral collateral ligament complex especially the anterior talofibular ligament. Most ankle ligamentous injuries are treated conservatively. However, 20% to 40% of patients complain of chronic instability and persistent discomfort. Structural instability, loss of proprioceptive capabilities, and the weakness of peroneal muscles seem to induce chronic instability

Inclusion Criteria:

Exclusion Criteria:

1. Tumors at ankle region.
2. Postoperative status around the ankle.
