Abstract:
Background:The study of the anatomical structure of the ankle joint ligaments is essential for understanding the stability, axis, and movement of the joint, as well as their interrelationship with the function. It also provides fundamental quantitative data for the training and research of physiotherapists, as well as the practice of injury and trauma medicine. Proper diagnosis and treatment of ankle joint injuries, as well as understanding the mechanism of injury, are based on this knowledge. Ankle joint injuries are common, with ligament and tendon injuries accounting for 85% of ankle injuries. In Mongolia, 81.1% of ankle injuries are new, 9.4% are similar to the initial injury, 8.1% are recurrent injuries, and 0.7% have unknown causes. Depending on the mechanism of injury, certain ligaments and connective tissues can be damaged. Ankle ligament injuries are the most common cause of acute ankle pain, and chronic ankle pain is often due to structural changes in the ankle ligaments.
Aim:To summarize the research on the normal anatomy of the ankle and subtalar joint, as well as the studies on joint injuries, using the dissection method.
Materials and Methods:Literature search was conducted in Thomson Reuters, Pubmed central database, Google Scholar, and Web of Science databases, as well as the statistical data from the Health Development Center and the National Center for Trauma and Orthopedics. Keywords used include: ankle joint, subtalar joint, ankle joint and subtalar joint injuries. A total of 330 publications were identified, and 34 key articles on the normal anatomy of the ankle and subtalar joint, as well as joint injuries, were included in the review.
Results:The ankle joint is formed between the distal end of the tibia and the superior articular surface of the talus. It allows plantar flexion and dorsiflexion movements, with a normal range of 30 degrees for plantar flexion and 50 degrees for dorsiflexion. The subtalar joint is formed between the posterior articular surfaces of the talus and calcaneus. It allows inversion and eversion movements, with a normal range of 35 degrees for inversion and 20 degrees for eversion. The ankle ligaments are divided into three groups: lateral, medial, and inferior tibiofibular (syndesmotic) ligaments. The most common cause of ankle joint injuries is excessive inversion of the subtalar joint, leading to injuries to the joint capsule, lateral and medial collateral ligaments, and the syndesmotic ligaments. Excessive plantar flexion and dorsiflexion of the ankle joint can also cause injuries to the posterior talofibular ligament, the osteochondral region of the talar neck, and the anterior-inferior margin of the tibia.
Conclusion:Comprehensive study of the ankle joint structure provides the basis for explaining the mechanism of injury. Further research in Mongolia is needed, combining dissection and imaging techniques, to develop standardized evaluation protocols that correlate with clinical outcomes.
