In clinical practice, weight bearing should be done under the guidance of a physician after a fracture has been properly treated. If weight-bearing exercise is done too early, it may lead to secondary displacement of the fracture. This is especially true for fracture patients who are treated conservatively after fracture, given manipulative reduction and external fixation with plaster casts or braces, small splints, and so on. Premature weight bearing can lead to muscle pulling on the broken end, which is prone to secondary displacement. If the fracture is treated surgically with incisional reduction and internal fixation, premature weight-bearing exercise may lead to plate breakage or nail breakage, which is prone to accidents. Therefore, when patients use weight-bearing exercise, should be under the guidance of the doctor or take the X-ray film of the fracture end, confirming that the fracture position is ideal and the fracture end is well healed, before considering weight-bearing exercise. Patients should not go down to the ground too early to exercise on their own and feel good about themselves, as accidents may easily occur.
