If an external fixation brace is used to fix the fracture end after a fracture, it will take about 3-6 months to be removed, which must be decided according to the recovery of the fracture. If the fracture is an ordinary upper limb fracture, there is no obvious damage or defect of the soft tissue at the fracture end, and the fracture heals relatively fast, the earliest is about 3 months, the fracture end will be able to have obvious growth of bone scab, and the fracture end is very stable, and the fracture end can be loaded with weight or subjected to mild gravity, then the external fixation bracket can be removed. However, if there is an open wound around the fracture end, and there is also a soft tissue defect or a very serious soft tissue injury, the blood circulation of the fracture end is relatively poor, and the fracture healing is relatively late, it may take 6 months before there is obvious bone scab growth. If you want to remove the external fixation bracket, you have to review the photos and see that there is obvious growth of the bone scab and the fracture end is not painful before you can remove it.
