Generally the internal fixation can be removed after the fracture in about 8-12 months after the operation, 8-12 months fracture healing is very good, you can take out the internal fixation, internal fixation is taken out too early to prevent local re-fracture, because the local force to cover the fracture site is not very good healing, if trauma is easy to re-fracture. In addition, some special plates or internal fixation can be removed, for example, PFNA of hip joint for the elderly can be removed, and internal fixation of pelvic fracture and cervical fracture can also be removed, because the risk factor is larger and the side injury is more obvious. If the plate cannot be removed prematurely after the fracture, there will be bone scabs wrapped around the plate and it will be more difficult to take it.
