Background
Fracture is a common and frequently encountered disease in orthopedics. Once a fracture occurs, it can result in various degrees of disability, serious or even fatal disability for the patient. The ultimate goal of treating fractures is to maximize the recovery of function of the injured limb. Therefore, in the surgical treatment of bone fracture, reduction and fixation thereof are important. Studies have shown that during fracture healing, pressure perpendicular to the fracture line favors fracture healing, while shear forces parallel to the fracture line easily cause dislocation of the broken ends, which in turn can lead to delayed healing and even nonunion.
For lower limb fracture, patients need to gradually bear weight to complete recovery after operation. However, continuous and effective rehabilitation guidance is lacked in the rehabilitation process. Partial patients have too large underground load, which may cause secondary fracture. In many elderly patients, particularly patients with osteoporosis and fracture, the psychological stress is high and the patients do not dare to bear weight during rehabilitation, which may result in delayed healing. The method that the affected limb steps on the electronic scale can be adopted to control the weight of the load more accurately, but the weight change of the load during the rehabilitation period can not be continuously and accurately adjusted according to the self condition of the patient, and in addition, the force of some patients is controlled excessively and even secondary damage can occur.
