From left to right: Fracture of the neck, body and posterior process of the talus. The talus bone lacks a good blood supply. Because of this, healing a broken talus can take longer than most other bones. One with a broken talus may not be able to walk for many months without crutches and will further wear a walking cast or boot of some kind ...
Unlike the flexible flat foot that is commonly encountered in young children, congenital vertical talus is characterized by presence of a very rigid foot deformity. The foot deformity in congenital vertical talus consists of various components, namely a prominent calcaneus caused by the ankle equines or plantar flexion, a convex and rounded sole of the foot caused by prominence of the head of ...
A varus deformity is an excessive inward angulation (medial angulation, that is, towards the body's midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. The terms varus and valgus always refer to the direction that the distal segment of the joint points.
The three aforementioned parts of bone articulate with the talus bone of the foot. Strictly speaking, there are only two malleoli (medial and lateral), but the term trimalleolar is used nevertheless and as such is a misnomer. The trimalleolar fracture is also known as cotton fracture.
Type IIIAC: two fracture lines are present, one lateral and one medial. Type IIIBC: two fracture lines are present, one central and one medial. Type IV fractures consist of fractures with more than three intra-articular fractures. Extra-articular fractures include all fractures that do not involve the posterior facet of the subtalar joint.
The first mechanism is a stress fracture which happens commonly in athletes, [7] and the other mechanism is a high energy trauma. The navicular bone is a keystone of the foot: it is part of the coxa pedis and articulates with the talus, first, second and third cuneiform, cuboid and calcaneus.
The subtalar joint is particularly susceptible to arthritis, especially when it has previously been affected by sprains or fractures such as those of the calcaneum or talus. Symptoms of subtalar joint arthritis include pain when walking, loss of motion through the joint's range of motion, and difficulty walking on uneven surfaces.
In the human body, the tarsus (pl.: tarsi) is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot ( cuboid , medial, intermediate, and lateral cuneiform , and navicular ) and hindfoot ( talus and calcaneus ).
