LIGAMENTOUS INJURIES OF THE ANKLE JOINT
Ahmed Sayed Badawy;
Abstract
Ligamentous injuries of the ankle are one the most common problems seen by
• general practioners and emergency physicians. The ligaments of the ankle can be divided into four anatomic groupings: The lateral ligaments, the lateral subtalar ligaments, the medial ligaments, and the distal tibiofibular interosseous ligaments. The lateral ligamentous complex consists of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL), and the posterior talofibular ligament (PTFL).
The ATFL is the most frequently injured ligament in the human body
The CFL is a cylindrical structure that lies deep to the peroneal tendons.
• Structurally, it is 2.5 times strongr than the ATFL.
The PTFL is the strongest of the lateral ligaments and is the least often injured.
The lateral subtalar ligaments are quite complex and include five separate structures: the CFL, the inferior extensor retinaculum, the lateral talocalcaneal ligament, the cervical ligament, and the interosseous talocalcaneal ligament.
The medial ankle or deltoid ligament is a strong fan-shaped structure that IS
composed of a deep and superficial layer.
The distal tibiofibular interosseus ligamentous complex , and consists of the anterior inferior tibiofibular ligament (AITFL), the posterior inferior tibiofibular ligament (PITFL), and the interosseous ligament. In addition, the interosseous membrane contributes slightly to the stability of the distal tibiofibular articulation.
When the body is upright and the foot at right angles to the leg, active movements of the joint are dorsiflexion ( 10°) and plantar flexion ( 20°), In the horizontal plane, the ankle axis projects from anteromedial to posterolateral .
The easily understood classification of the lateral ligament complex (grade I, stretch, intact ligaments; grade II, partial tear; grade III, complete rupture) . Complete syndesmotic rupture in the absence. of fractures or plastic deformation of the fibula is rare. Although there is a continu,um of injury from grades I to III, the most clinically useful classification scheme uses the terms latent and frank diastasis.
