Fixation can be divided into two types: external fixation and internal fixation. External fixation refers to the use of plaster, traction, splints and other appliances to achieve fixation outside the body. Internal fixation refers to the surgical technique of using metal or biomaterials to maintain alignment and stability of the fracture after the fracture has been repositioned. If you are treated with internal fixation, it is not necessary to remove it because with the improvement of internal fixation devices, it is generally difficult for the patient to feel them even if they are in the body, they cause neither pain nor special discomfort, and some people can carry them for life. However, depending on the situation, some patients may need to have the device removed, which means that you will need to return to the hospital after a period of recovery. This means that you will need to return to the hospital after a period of recovery, so you must be concerned about when these fixations will be removed. Usually it depends on whether the fracture has healed completely or not. If the fracture is completely healed, the support of the internal fixation is no longer needed, and the movement of the joint adjacent to the fracture has been restored to the maximum extent possible, so that functional exercises are not affected by the surgery to remove the internal fixation. The internal fixation can be removed at this time. To achieve this condition. It takes more than half a year for the fracture of extremity. Therefore, the time to remove the fracture internal fixation is generally six months to -year after the surgery. However, this is not absolute, in some children’s fractures such as supracondylar humerus fracture, the healing is faster, and the internal fixation can be removed in 2-3 months after surgery, but in some special cases, such as infection at the fracture site, the internal fixation needs to be removed even if the fracture site is not healed, because once the wound is infected, the internal fixation becomes a foreign body, which will cause the wound not to heal.
