There are many things to consider after having bone cement, such as diet, rest, and complications. 1. Diet: you need to maintain a nutritious diet after the operation, such as high protein food, eggs, soy products and so on. At first, you should eat easy-to-digest liquid food, such as fish soup, rib soup, etc., and then eat normally after a period of time. 2. Rest: It is absolutely necessary to stay in bed for a period of time after the operation, partly because the cement is not yet completely solidified to prevent aggravation; on the other hand, the operation will leave slight wounds, and bed rest can reduce pain, and also accelerate recovery. 3. Complications: Some patients may be allergic to the bone cement, and the wound will be red and swollen. There are many other precautions after doing bone cement, such as observing whether side leakage of bone cement occurs, don’t move too early, etc. If there is any adverse condition, it is recommended to go to the hospital for consultation in time.
