ABSTRACT: The ligaments of the ankle joint are medial and lateral collateral ligaments. Medial deltoid ligament has superficial and deep components. Lateral collateral ligament has Anterior Talofibular (ATFL), Calcaneofibular (CFL) and Posterior Talofibular ligaments (PTFL) as three discrete parts. Ankle sprains are most common in athletes and in other sports like basketball, soccer, football and volleyball. Lateral ankle sprains account for about 85% of all ankle sprains; with anterior talofibular ligament being the most frequently injured. A total rupture involves the calcaneofibular ligament and the posterior talofibular ligaments as well. An eversion injury will cause damage to the deltoid ligaments. Morphometry and variations of ligament of ankle has not been well documented in literature. Hence this study has been taken up. Study was done by dissection on 60 cadaveric lower limbs, irrespective of sex from the Department of Anatomy, Kempegowda Institute of Medical Sciences, Bangalore. The mean values of length, width, and thickness of CFL was found to be 27.00mm, 5.45 mm, 1.64mm respectively. The detailed anatomical knowledge of these ligaments, variations and their relations with osseous structures may provide a foundation for understanding the basic mechanism of injury, diagnosis and reconstructive procedures.
