摘要
the lateral talofibular ligament injuries are a common problem in trauma. these correspond to the majority of ankle sprains, anterior talofibular ligament being the most frequent, followed by the calcaneal fibular. through our study we will try to describe the anatomy of these ligaments, thus having a surgical tool for confrontation. a descriptive study was conducted on the morphometric lateral talocrural ligaments, resulting in an average of their measurements and frequency of anatomical variations. were dissected 27 limbs from amputation with no history of age, sex and morbidity. the ligaments were measured with a tube foot, dry dividers and millimeter ruler, expressing the results in millimeters. we measured the length (l), width (a), thickness (e), area of origin (o) and insertion site (i). described the anatomic variations presented these ligaments. the results were: fibulocalcaneal ligaments (l = 30.3 mm, a = 5.46 mm, e = 2.4 mm, ao = 46.17 mm2; ai = 66.59 mm2). no anatomic variations presented. posterior talofibular ligament (l = 25.74 mm, a = 6.37 mm, e = 4.35 mm, ao = 40.1 mm2; ai = 80.19 mm2). in 22.2% described a projection accessory fiber (fascicle up or fibular) arising from the origin of the ligament, superior heading to attach to the articular surface of the fibula. anterior talofibular ligament (l = 20.01 mm, a = 10.2 mm, e = 2.3 mm, ao = 60.03 mm2; ai = 66.96 mm2). in 57% of cases was unique, bifurcated in 43% and 0% triple-barbed. a 46.15% have arcuate fibers connecting the origins of the anterior fibulotalar and fibulocalcaneal ligaments. in conclusion important anatomical variations were found are not isolated, but form distinct anatomical groups each ligament.
