People often say “a hundred days to move the bones”, but in fact this is not true. Injury tendon is also called soft tissue injury, including skin, muscle, tendon, tendon sheath, fascia, ligament, nerve, blood vessels, joint capsule, cartilage, intervertebral disc and spinal cord injury; and moving bone generally refers to fracture. Generally speaking, the recovery time for skin, muscle, tendon, tendon sheath, fascia, blood vessel, and joint capsule is about 1-2 weeks, while the recovery time for ligament, joint capsule, and cartilage is slightly longer, about 3 weeks, and the recovery time for nerve, disc, and spinal cord is longer because the daily growth rate of nerve is 0.1 mm, and the recovery time for disc is slower because of the lack of sufficient blood flow. The healing of fractures is related to their location (the prerequisite is a better reset after fracture) and is divided into clinical healing and bony healing. In addition, there are many fractures, such as wrist bone, tarsal bone, spinal bone, etc., which cannot be completely measured by time and should be determined by combining the X-ray performance with the clinical reality and referring to the comprehensive analysis of the treatment time. In children, the younger the age, the shorter the clinical healing time of the fracture, because they are in the growth and development stage, while the opposite is true in the elderly. The conditions of clinical healing criteria are as follows: (1) No local pressure pain (2) No local longitudinal buckling pain (3) No abnormal local activity (4) X-ray shows faint fracture line with continuous bone crust through the fracture line (5) Functional measurement: holding one kilogram of weight for one minute with the upper limb held forward; walking continuously on the flat ground for 3 minutes without crutches for the lower limb, not less than 30 steps (6) Continuous observation for two weeks, no deformation at the fracture site. Care must be taken in the determination of (3) and (5) of the clinical healing criteria. Criteria for osseous healing: (1) The conditions of the clinical healing criteria are present (2) Radiographs show bone scabs passing through the fracture line and the fracture line disappearing or nearly disappearing. It must be noted that nerve healing time is relatively short in the case of concussive or strain injuries, while recovery time is longer or even non-healing in the case of nerve rupture injuries. Among the bones of the body, fractures of the carpal navicular, talus, femoral neck and lower third of the tibia are prone to non-healing or delayed healing due to insufficient blood supply to the fracture end. Therefore, the recovery time after a fracture varies depending on the fracture site; moreover, the healing time of a fracture in the same site varies depending on the type of fracture, such as a fracture in the heel bone is significantly shorter than that of a comminuted fracture. Patients should not remove the fixation as a matter of course after the fracture is reset and fixed, but should follow the doctor’s instructions to prevent adverse consequences.
