Nursing care for elderly bone cancer mainly includes rehabilitation training, emotional care and dietary care. 1. Rehabilitation training: If elderly bone cancer patients have undergone limb preservation surgery, they need to carry out walking training or active activity training, which can help the elderly to resume independent daily life quickly. If prostheses are installed, it is necessary to pay attention to the cleanliness of the skin of the residual limb in contact with the prostheses to prevent skin abrasion and breakage. 2. Emotional care: Elderly patients may have more fear after diagnosis. Family members need to pay attention to the emotions of the elderly, encourage the elderly to actively cooperate with the treatment, and relieve tension and anxiety. 3. Dietary care: Diet needs to ensure nutritional balance, diversify food types, and avoid spicy, greasy and other stimulating foods. You can eat more protein-rich foods, such as eggs, milk, lean meat and so on. Due to the deterioration of the bone quality of the elderly, trauma should be avoided as much as possible, and it is recommended to consult a doctor in time if symptoms of discomfort occur.
