Description

Fixing assembly for preventing leg fracture

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a fixing component for preventing leg fracture.

Background

As the population ages, the incidence of leg fractures increases year by year and patients often incorporate severe osteoporosis as a result of multiple occurrence in elderly patients. Because the fracture of the legs needs to be braked in bed no matter whether the operation is prevented or not. Thus, bedridden related complications such as urinary system infection, intrapulmonary infection, bedsores, deep venous thrombosis of lower limbs and the like are often the main causes of the final adverse consequences of patients with leg fracture. In addition, joint replacement surgery is often required for fracture of the femoral neck, and the like, so that the surgery is relatively traumatic and is often intolerable for elderly patients. Thus, for leg fractures, prevention is greater than prevention. The effective prevention of leg fracture can significantly improve the life quality of elderly patients, so that an intervention means for effectively preventing leg fracture is urgently needed clinically.
