Foot fracture more than 60 days to grow bone scab, consider local fracture displacement, malnutrition, severe local soft tissue injury, surgical disruption of blood flow. Factors affecting fracture healing include systemic factors such as advanced age, malnutrition, and metabolic disorders. Local factors include the location, type, and degree of the fracture, improper treatment or care, poor blood supply to the fracture end or less surrounding soft tissue over severe soft tissue damage, localized infection of the fracture, and poor quality or improper use of metal internal fixation devices. If it takes more than 60 days for the bone scab to grow after a foot fracture, consider the fracture to be severe and significantly displaced, but not effectively immobilized. Poor nutrition after fracture can also cause delayed healing. Severe local soft tissue destruction or surgical destruction can cause poor local blood flow, poor blood circulation, and poor bone nutrition, which can also affect the formation of bone scabs. Delayed formation of bone scab after fracture is recommended to actively consult the doctor and standardize the treatment under the guidance of the physician.
