Fracture healing process and influencing factors

After fracture, usually after manual reduction and external fixation or fracture open reduction and internal fixation surgery, fracture broken end can obtain relatively good stability, then on this basis, there will be a continuous healing process, mainly including hematoma activation evolution, original callus formation and callus shaping stage. Generally, callus can begin to form at the fracture end in about two weeks. Normally, after 4~6 weeks, a large number of callus will gradually form, and the fracture end will be relatively stable. At this time, the external fixation can generally be removed and appropriate functional activities and exercises can be carried out. The normal callus shaping is accompanied by a long process of functional exercise for the patient, which takes about half a year to one year. Factors affecting fracture healing mainly include: Fracture soft tissue condition, blood supply condition, nutritional status of the patient, fracture reduction condition, and stability, etc.
