The deltoid ligament (or medial ligament of talocrural joint) is a strong, flat, triangular band, attached, above, to the apex and anterior and posterior borders of the medial malleolus. The deltoid ligament supports the ankle joint and also resists excessive eversion of the foot. [1] The deltoid ligament is composed of 4 fibers:
The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. [3] The talus has joints with the two bones of the lower leg, the tibia and thinner fibula. These leg bones have two prominences (the lateral and medial malleoli) that articulate with the talus.
The summit of the medial malleolus is marked by a rough depression behind, for the attachment of the deltoid ligament. The major structure that passes anterior to the medial malleolus is the saphenous vein. Structures that pass behind medial malleolus deep to the flexor retinaculum: Tibialis posterior tendon; Flexor digitorum longus
The ankle joint is bound by the strong deltoid ligament and three lateral ligaments: the anterior talofibular ligament, the posterior talofibular ligament, and the calcaneofibular ligament. The deltoid ligament supports the medial side of the joint, and is attached at the medial malleolus of the tibia and connect in four places to the talar ...
However, human feet, and the human medial longitudinal arch, differ in that the anterior part of the foot is medially twisted on the posterior part of the foot, [12] so that all the toes may contact the ground at the same time, and the twisting is so marked that the most medial toe, the big toe or hallux, (in some individuals the second toe ...
Pott's fracture, also known as Pott's syndrome I and Dupuytren fracture, is an archaic term loosely applied to a variety of bimalleolar ankle fractures. [1] The injury is caused by a combined abduction external rotation from an eversion force.
It passes obliquely forward and lateralward, superficial to the deltoid ligament of the ankle-joint, into the sole of the foot, where it crosses over the tendon of the flexor hallucis longus at the level of the navicular bone at a location known as the knot of henry [6] (also referred to as plantar tendinous chiasm), [2] [3] [4] and receives ...
Ankle radiographs are used to detect widening of the tibiofibular syndesmosis or medial clear space. The medial clear space is the area between the talus of the ankle and the medial malleolus. Damage to the deltoid ligament and syndesmotic ligaments result in mortise instability, causing the talus to laterally shift and widen the medial clear ...
