The more common sequelae of thigh fractures are infection, bone inequality, bone failure, muscle atrophy, muscle adhesions, and lower limb claudication, which are more likely to cause these complications. The occurrence of these complications can be reduced through prevention, which requires the guidance of an orthopedic surgeon, such as special fixation treatment for patients with bone non-union and bone non-union for their specific reasons. In patients with muscle atrophy, effective functional rehabilitation exercises should be carried out in advance after fracture fixation, which can effectively prevent muscle atrophy. In addition, fracture disease is also a common complication of fracture, which is relatively annoying but can be prevented by early intervention and can be prevented by normal diet, functional exercise and medication.
