Early fracture of the calf is not in favor of running, it is generally believed that early fracture can not run, after 3-6 months of recovery, you can do brisk walking, jogging and other sports. Early fracture if the fracture alignment is poor, there is bone rubbing sound or bone rubbing feeling, abnormal activity, it is not possible to run. The early fracture will stress the calf when running, which is not conducive to the healing of the fracture in the early stage and may produce secondary fracture, and more serious may affect the blood flow situation, delayed healing or even non-healing of the fracture, or may produce ischemic myospasm and cause osteofascial compartment syndrome. After 3-4 months of recovery, jogging is usually not a problem. If the fracture is clinically healed and there is no abnormal activity, the fracture can be considered to be clinically healed if more bone scabs are produced and the fracture line is blurred. If you want to do some strenuous exercises such as fitness, it is more appropriate to do so after 6-8 months.
