Die Ausprägung von elastischen Fasern ist vom Alter und von der mechanischen Beanspruchung des jeweiligen Bandes abhängig [1], [5]. 3. cordlike remnants of fetal tubular structures that are nonfunctional after birth. The tibiocalcaneal ligament, a portion of the triangular deltoid ligament of the inner ankle, vertically connects the heel bone to the inner side of the tibia bone just above the ankle joint.

The tibiocalcaneal fascicle of the deltoid ligament was studied in 10 lower leg amputation specimens to evaluate its stabilizing effect on movement in the tibiotalocalcaneal joint complex and the talocalcaneal joint complex. Tibiocalcaneal ligament: composes the intermediate part of the medial collateral ligament that passes almost vertically downwards from the medial malleolus to attach onto the sustentaculum tali. The tibiocalcaneal and tibiospring ligaments are the longest, and the tibiocalcaneal and posterior deep tibiotalar ligaments are the thickest of these ligaments. Laterally the ankle has stabilization from three separate ligaments, the anterior and posterior talofibular ligaments, and the calcaneofibular ligament.

They connect two adjacent bones of a joint and provide support from all the for direction. Die Verteilung der elastischen Fasern im Gewebe reflektiert dessen Funktion [10], [11]. Judging by the literature, the function of the tibiocalcaneal ligament seems comprehensive, since it is reported to limit external rotation, dorsiflexion, as well as plantar flexion. May sometimes be absent (10). Ligaments are the soft tissue structures that connect bones and actually help define the function and degree of motion that joints are permitted. It is placed in front of, but on a deeper plane than, the calcaneofibular ligament, with the fibers of which it is parallel. The tibiocalcaneal ligament fibers are most commonly inseparable from the more anteriorly arising tibiospring ligament (TSL) which bridges from the medial malleolus to the superomedial portion of the spring ligament complex (SL). ligament [lig´ah-ment] 1. a band of fibrous tissue connecting bones or cartilages, serving to support and strengthen joints. The major ligament of the medial ankle is the deltoid ligament, which is made up of three distinct structures, the anterior and posterior tibiotalar ligaments, and the tibiocalcaneal ligament. The tibiocalcaneal and the intermediate tibiotalar ligaments control abduction of the talus. It is located superficial to the deep anterior tibiotalar ligament, anterior to the tibiocalcaneal ligament and posterior to the tibionavicular ligament or rather to the anterior ankle joint capsule. The tibiocalcaneal and tibiospring ligaments are the longest, and the tibiocalcaneal and posterior deep tibiotalar ligaments are the thickest of these ligaments.

According to this theory, certain fibers in the calcaneofibular and tibiocalcaneal ligaments remain isometric during passive dorsiflexion or plantar flexion; others are recruited throughout the flexion arc and under load in activity. Created by. Vertebrae of the spine. Deltoid ligament. 12, ,13). Spell. Conclusion: Our results show the biomechanical function of the superficial deltoid ligament and may contribute to determining which ligament is damaged during assessment in the clinical setting. It connects the medial tibial malleolus with the spring ligament 1-6.The tibiospring ligament becomes tenser with eversion and plantarflexion 7. The lateral talocalcaneal ligament (external calcaneo-astragaloid ligament) is a ligament in the ankle.It is a short, strong fasciculus, passing from the lateral surface of the talus, immediately beneath its fibular facet to the lateral surface of the calcaneus.. ture represents a more functional unit than an isolated ligament.6 8 e 12 26 27'35'36 Various other factors which may affect the mechanical properties of ligaments … Ligament.
