When the skin of the fracture is swollen or the skin is open, it can be fixed with an external fixation brace. The external fixation brace is only a temporary maintenance fixation, and after the swelling is reduced or the local skin is healed, it can be treated with other methods, such as internal fixation with plates or intramedullary nails, because internal fixation with plates and intramedullary nails is a kind of fixation with less stress masking. If the fracture is fixed with an external fixation brace, there will be serious stress masking, which may lead to non-healing or atrophy of the fracture end, etc. Taking plate or intramedullary nailing can change the stress masking and promote fracture healing. In addition, the intramedullary nailing treatment can be used to get out of bed early after surgery in good bone quality.
