Depending on the healing of the fracture, it is normal to remove the external fixation in about 3~4 months. Some patients with poor skin conditions, or open fracture external fixation bracket time should be appropriately extended until the skin conditions improve. The use of external fixation bracket for fracture is mainly seen in the fracture of the broken end is serious, it is difficult to get a good restoration of the cut-and-replace plate internal fixation, then the external fixation bracket can be used to cross the broken end of the broken end of the two sides of the fixation of the broken end, postoperative regular review of the X-ray film, usually in 3~4 months can be seen in a large number of scab formation, the fracture has formed a preliminary stable structure, then the external fixation bracket can be removed. When there is an open fracture, usually the incision is seriously contaminated, and performing a one-stage surgery is likely to cause incision infection, plate exposure, etc. In severe cases, it can cause osteomyelitis, so it is usually temporary fixation with external fixation bracket first. However, in many cases, the skin condition cannot return to normal in 3~4 months and cannot adapt to the second surgery, in which case the use of external fixation bracket should be extended appropriately. If you have any of the above conditions, it is recommended that you visit a specialized orthopedic clinic to avoid delays.
