The healing of metatarsal fractures is similar to the healing time of fractures in other parts of the body, about 3 months. Clinical includes three periods: 1, hematoma mechanization evolution period: hematoma mechanization, the formation of granulation tissue, fibrous connective tissue, about 2-3 weeks; 2, primitive bone scab formation period: endosteal scab, exosteal scab and cartilage endosteal osteogenesis formation, about 4-8 weeks; 3, bone scab modification and plasticization period: primitive bone scab through the modification and plasticization of the development of a permanent bone scab, the bone marrow cavity recommencement, the bone morphology recovery, about 8-12 weeks. If the patient is combined with chronic consumptive diseases, such as diabetes, malnutrition, calcium and phosphorus metabolism disorders, malignant tumors, etc., as well as premature and inappropriate functional exercise, will prolong the fracture healing time. Therefore, patients should follow the doctor’s instructions and eat appropriate nutrients during treatment to promote fracture healing.
