title: The anterior talofibular and calcaneofibular ligaments: an anatomic study.
abstract: Inversion injuries of the ankle are the most common sport injuries. Extreme inversion of the ankle affects frequently lateral ankle ligaments, especially the anterior talofibular and calcaneofibular ligaments. The aim of this study is to investigate the ligaments in detail to contribute to accurate evaluation of radiological investigations and more precise surgical interventions by clarifying the anatomic structure of the ligaments by considering their functional importance. In the study, length between the attachment points and width at the midpoint of the anterior talofibular and calcaneofibular ligaments, length and width of the bands of anterior talofibular ligament, and connecting ligaments extending from the talus to calcaneus exchanging from the both ligaments were measured on the 46 ankles. In addition, angles between these ligaments and between longitudinal axis of the fibula and both ligaments were measured. Relationship between determined variables on the right and left sides was statistically analyzed. In diagnosis and treatment methods, the clinical importance of the anatomy of the lateral collateral ligaments of the ankle, especially the anterior talofibular and calcaneofibular ligaments, was frequently reported in the literature. Angular measurements benefit in determination of the ligament injury. Therefore, knowledge about normal anatomic angles between each other and angles between longitudinal axis of the fibula and both ligaments was certainly important for the correct diagnosis. Nowadays, surgical reconstructions of the ligaments are frequently used. During the surgical invention, length and width of the ligaments are necessary to determine quantity of ligament loss. Nonetheless, knowledge of ligament attachments contributes to more accurate reconstructions.
