For the sequelae of bone fractures, usually, patients who have sustained a fracture will not have sequelae if they actively cooperate with treatment. However, if treatment is improper, a series of sequelae can easily occur, with the most common manifestations being the following.

First, after the fracture, if there is no active and strict attention to rest, protection, and immobilization, later muscle traction can cause displacement at the site of the fracture, leading to deformity healing and affecting the patient's normal function.

Second, after a fracture, due to prolonged inactivity, the joints may become stiff and the muscles may contract. When it becomes possible to exercise later, patients may exercise insufficiently due to fear of pain, resulting in very poor joint mobility, which affects the normal function of the patient.

Third, for fractures in some special areas, such as a femoral tibial fracture, this may lead to avascular necrosis of the femoral head in patients.
