Do you know why you should give up your seat to the elderly in public transport? Because, the bones of the elderly is really very fragile, young people bump may be nothing, while the elderly due to the higher incidence of osteoporosis, the bones are like a fragile cookie, “a word” may occur in an accident. Once fallen, it is easy to fracture, and the femoral neck fracture is one of the most common and very serious consequences. Where is the neck of the femur? The femur is the largest long tubular bone in the body. The upper end faces inward and the end is enlarged and spherical, which is often referred to as the femoral head. The femoral neck is the thinner part of the femur at the bottom of the femur. The femoral neck is the gravitational support system for the upper end of the femur, through which the body’s forces and weight are transmitted to the lower extremities. Why are older people prone to fractures? As we age, osteoporosis occurs quietly, the trabeculae in the femoral neck gradually loosen, the density and quality of the bones decrease, the bones of the human body are like “wood” gradually decaying, becoming very fragile, and fractures are easy to occur. What are the symptoms of femoral neck fracture? Fracture of the neck of the femur is mostly caused by sudden fall or external violence, and after the fracture occurs, there is pain in the hip (also known as the “crotch”), afraid to stand, shortening of the affected limb, etc. However, there are some cases that can still walk or ride a bicycle after the injury, so it should be carefully examined. It should be noted that elderly people are less sensitive to injury stimuli and have reduced peripheral nociception, so even if an elderly person reports that it is not very painful, it does not exclude the possibility of serious damage. IV. What are the complications? 1. Non-healing of femoral neck fracture Non-healing of femoral neck fracture occurs more commonly. Ischemic necrosis of the femoral head is a common complication of femoral neck fracture. The blood flow at the femoral neck is poor, and the femoral neck fracture will destroy the arterial ring, resulting in the loss of most of the blood supply to the femoral head, which eventually leads to femoral head necrosis. V. How to treat femoral neck fracture? 1.Conservative treatment: The main method is traction treatment. If the indications for surgery are met, surgery is generally preferred. Conservative treatment is only performed if the patient is intolerant to surgery, has severe comorbidities or is in extremely poor health. 1, surgical treatment: (1) internal fixation; (2) artificial hip replacement; internal fixation: if the fracture site has a good blood supply and healing is not a problem, doctors will generally use internal fixation. However, for the elderly, the chance of healing and femoral head necrosis is very high, and the chance of failure of internal fixation is very high, and femoral head necrosis is likely to occur, so joint replacement is generally recommended at present. Artificial joint replacement: This is a method of replacing one’s own joint with an artificially made joint. Artificial joints are now very well established. Currently, artificial joint replacement is recommended for patients over 65 years of age, and for patients over 55 years of age who are in poor general condition and have significant fracture displacement. For the rest of the age group, internal fixation is recommended as much as possible. Finally, either treatment is painful for the patient, and without a fall there would be no fracture. Prevention of femoral neck fracture starts with fall prevention.
