What is the appropriate time to remove the internal fixation after fracture surgery? The removal of internal fixation after fracture should follow the following principles: whether the fracture is healed, the material and implantation site of the internal fixation device, and the time of implantation. Generally speaking, the fracture can be removed only after the fracture is healed by the help of the internal fixation device and the fracture bone grows well and firmly within the specified time. Usually the recommended time for removal of internal fixation is 6 to 12 months after surgery in children and 12 to 18 months after surgery in adults. The material of the internal fixation device and the site of implantation are also important factors in determining if and when the implant should be removed. Not all implants must be removed due to the material of the implant, for example, intervertebral implants in the spine are usually not removed. If the implant is deep or near a critical nerve or blood vessel, the risk of removing such an implant may be greater than the safety of permanent retention in the body, and it is not recommended, for example, internal fixation devices for acetabular fractures may not be removed. In addition, if the implant has been in place for too long, it is usually considered that if the implant has been in the body for more than 2 years, it is generally not recommended to remove it again, because the damage to the tissue around the implant may be great.
