What is the talus?

Talus je kost v noze, která hraje důležitou roli při artikulaci kotníku. This bone transmits the body weight to the leg, provides stabilization that allows people to walk, and glides with a series of bones to create a wide range of movement for the ankle joint. Talus je součástí většího shluku kostí v noze známé jako Tarsus; Tarsus kosti tvoří kotník a zadní část nohy a připojují se k kostem, které nakonec vedou k prstům.

Tato kost má tvar, který poněkud připomíná želvu. Připojuje se k holenní a fibule v nohou a kosti navikulárních a kabátů v nohou. The talus structure allows him to have a somewhat curious blood supply in which arterial blood enters from the bottom of the bone, rather than from above, as more conventional with other bones in the skeleton. Talus is also covered with so -called articular cartilage, a type of cartilage that creates a smooth surface for articulation so that the bone can move freely inside the joint.

ZlOmen's talus is sometimes associated with traffic accidents and falls, and orthopedic surgeons have also noted that they are particularly common in snowboarding injuries, as snowboard shoes do not offer complete ankle support. Talus injury can be very problematic, which requires the patient to spend up to three months from the foot to prevent bone injuries when healing, and the talus is susceptible to the development of avascular necrosis in which the blood supply to the bone is interrupted, causing bone to die.

In a simple talus fracture, the surgeon can be able to treat the patient by putting the leg in the cast and leaving the cast for at least six weeks. If the bone seems to heal well and the blood supply is healthy, the cast may be removed, even if the patient will have to attach the Avoid to the foot for the next six weeks. More serious fractures require surgery to move and attach the bone and the risk of necrosis increases in such fractures.

If the bone begins to die, mThe surgeons are several options, including bone drilling to support the formation of new blood, combine ankle or replace the ankle joint with an artificial joint. The correct healing of talus fracture is critically important because the damage to the bone can reduce freedom of movement in the leg, causing discomfort and making someone a more susceptible fall. There is also a risk of arthritis that can be quite weakening to the patient.
