Description

Ankle joint injury correction fixation brace

technical field

The utility model relates to the technical field of medical devices, in particular to an ankle joint injury correction and fixation support.

Background technique

Ankle sprains are extremely common in life, and almost everyone has the experience of "scared feet". Minor sprains can heal on their own without special treatment. For mild ankle soft tissue injuries or simple ankle fractures, if no fixation treatment is given , it is easy to appear ligament laxity, and then cause habitual sprain due to joint ligament laxity.

At present, the main treatment plan is plaster immobilization or brace immobilization, and after surgical treatment of severe and complex ankle fractures and ligament injuries, it is often necessary to immobilize the ankle joint for a period of time to ensure the treatment effect. In addition to the disadvantages such as pigmentation, there is also the disadvantage of requiring multiple replacements, because the plaster fixation loosens after the swelling of the injury subsides, which increases the risk of malunion; while the brace fixation is light and breathable, it still needs to be replaced multiple times to avoid In addition, this type of treatment has an obvious drawback, that is, due to immobility after immobilization, complications such as Achilles tendon contracture and ankle stiffness will occur, which will affect the recovery of ankle joint function and reduce treatment satisfaction.
