The removal of internal fixation after lumbar fracture surgery is recommended after one year. The specific situation of internal fixation of fracture varies and needs to be determined according to the specific situation. For young patients, early removal is recommended if the internal fixation is partially broken or pulled out due to premature exercise, which already affects the normal bending activities. For some patients without obvious symptoms and not affecting normal life, it can also not be removed, especially for older patients, not removed can reduce the risk of surgical anesthesia. In the absence of other special circumstances, the internal fixation of the lumbar spine can maintain the stability of the spine for about three to six months, and after six months the bone quality has returned to the normal level, basically no internal fixation is needed, and further support can be removed, but clinically it is recommended that one year is more appropriate.
