Fractures of the extremities are the most common among total body fractures. Many patients follow the advice of their orthopedic surgeons for independent functional exercise, but patients often delay rehabilitation because of pain and other reasons, resulting in residual functional impairment and incomplete recovery. Therefore, many patients ask what is the most appropriate time for rehabilitation after fracture surgery. In fact, the clinical fracture situation is complex and cannot be generalized. Simple dry bones (such as fractures of the lower leg and forearm) can start exercising the day after internal fixation, while complex fractures of dry bones (such as comminuted fractures) should be appropriately delayed for rehabilitation depending on whether the internal fixation is firm or not, but the overall principle is also that the earlier the effect, the better. Patients who are not sure about the timing of rehabilitation should go to a professional rehabilitation department for consultation instead of listening to the surgeon’s opinion for independent exercise, because we have a survey that shows that close to 60% of orthopedic surgeons are only guided by experience for the rehabilitation of fractures, without relevant professional training, and 45% of orthopedic surgeons feel that they should strengthen their own learning of rehabilitation knowledge. to get the best recovery!
