At 70 days, a tibia fracture has generally recovered to the point of near clinical healing. Recovery after a tibia fracture is divided into three phases, the first is the hematoma inflammation mechanization period, the fracture broken end of the fracture at the beginning of the fracture bleeding, with time will be absorbed, usually two weeks time. At the same time, the broken end of the fracture begins to form a bone scab, which is formed four to eight weeks after the fracture. After the scab is formed, a strong bone plate begins to form under stress, which takes about 12 weeks. Seventy days after the tibia fracture, the bone scab has been formed and plate shaping has begun, essentially approaching clinical healing and allowing for active functional exercise and protected walking on the ground. All of the above statements are generalizations. Individual differences exist, so be sure to go to the hospital for review, according to the individual’s recovery situation, under the guidance of the doctor to carry out rehabilitation exercises. Do not walk on your own to avoid a series of negative consequences due to the slow healing of the fracture.
