Orthopedic surgeons Dr. Cole and Dr. Woolwine discuss ankle trauma, focusing on ligaments, syndesmosis stability, fracture classifications, and mechanisms. They delve into the roles of key ligaments in preventing misalignment, detailed examination of ankle components, fracture classifications, and decoding ankle x-rays for syndesmotic disruptions.
Ankle fractures in elderly women often result from simple falls, emphasizing the importance of preventive measures.
Understanding the components of the medial malleolus and associated ligaments is crucial for maintaining ankle stability and assessing fracture patterns.

Ankle Fractures in Elderly Women
Elderly women have the highest incidence of ankle fractures, often resulting from simple falls. The fibula externally rotates through the syndesmosis as the ankle dorsiflexes, widening to accommodate the talus. Ligaments like ATFL, PTFL, and CFL prevent talus inversion and anterior translation, crucial for ankle stability.
Medial Malleolus Components and Attachments
The medial malleolus consists of anterior, intercalar, and posterior malleoli. The anterior malleolus attaches to the superficial deltoid ligament, while the posterior malleolus and intercalar groove attach to the deep deltoid fibers. These components play a significant role in ankle stability and fracture patterns.
Classification of Ankle Fractures and Diagnostic Procedures
Ankle fractures are classified using systems like AO, Weber, and Lauge-Hansen classifications. The Weber system categorizes fibular fractures in relation to the syndesmosis. Diagnostic procedures include standard X-rays, stress views, and other tests to evaluate medial and syndesmotic injuries. The Ottawa ankle rules aid in determining the need for X-rays based on specific criteria like age, tenderness, and weight-bearing ability.
