Description

Technical Field

[0001] The present invention relates to the technical field of limb function rehabilitation, and particularly relates to a support and fixation bracket for leg fracture care. Background Art

[0002] Fracture, as a pathological state with impaired integrity of the bone structure, its treatment process not only involves precise reduction and stable fixation of the fracture site, but also covers a subsequent long rehabilitation period. During the recovery process of fracture patients, especially those with leg fractures, after initial emergency treatment, stable fixation of the fracture site and necessary surgical treatment, the patients gradually enter the rehabilitation stage. One of the key goals of this stage is to promote the healing of the fracture site, while ensuring that the leg muscles, joints and the entire lower limb system can gradually adapt to and relearn to bear weight and perform functional activities.

[0003] In the later stage of fracture healing, as the callus forms and the fracture line becomes blurred, the fracture site gradually obtains sufficient mechanical strength. However, walking directly on the ground at this time often leads to secondary injuries or delays the rehabilitation process. This is because long-term fixation and lack of activity not only cause muscle atrophy and joint stiffness, but also affect the adaptability of bones to pressure. Therefore, fracture patients need a series of gradual adaptive training in the later stage of rehabilitation to gradually relearn how to bear weight with the leg and how to coordinate muscles and joints for walking.

[0004] Traditional rehabilitation methods include using auxiliary devices such as crutches and walkers, as well as functional exercises under the guidance of physical therapists. However, these methods often lack precise adjustment according to individual fracture types and recovery progress, and it is difficult to simulate the dynamic pressure distribution borne by the leg during real walking. In addition, when patients recover at home by themselves, due to the lack of professional guidance and supervision, it is easy to have poor rehabilitation effects or even aggravate injuries due to improper training.

[0005] Therefore, the present invention discloses a support and fixation bracket for leg fracture care, which is a rehabilitation device that simulates the pressure borne by the leg during human walking, gradually increases the leg's load-bearing capacity, and can be flexibly adjusted according to individual recovery conditions, for accelerating the rehabilitation process of fracture patients and improving the quality of rehabilitation.
