After surgery, the common complications of scoliosis patients mainly include local infection, damage of internal fixation, and non-integration of local bone grafts, etc. The details are as follows: 1. Local infection: when this kind of patients undergo the surgery, it may produce greater trauma, and the time of the surgery may also be longer, which increases the chances of the patients’ local infection after the surgery; 2. Damage to internal fixation: for example, it may be loose or broken. Or fracture, for this kind of patients for fixation, may need to carry out multiple segments of the fixation, in the postoperative period if the patient has done intense activities, may lead to internal fixation loosening, or even completely fracture; 3, local implantation of bone is not fusion: for the treatment of this kind of patients, sometimes need to cooperate with osteotomies, and implantation of bone, so as to make the local fusion become a whole in postoperative period, but if the patient is too early or intense activities, it will lead to local infections. However, if the patient is too early to move around or is in intense activity, it will lead to non-healing here.
