Fracture line is the translucent shadow of the fracture area, which is clear at the beginning, but as the fracture gradually heals and localized bone scabs are formed, the fracture line tends to be blurred and eventually disappears gradually. The blurring of the fracture line suggests that the fracture is growing locally, and the growth of the local bone scab is more obvious, which is a better phenomenon in the process of fracture healing. The blurring of the fracture line only suggests that the fracture is in the process of healing, the fracture has not completely healed, this situation also needs to continue to rest, local places can not force, otherwise it may lead to the risk of fracture re-displacement. Drink more bone broth, eat more yam, angelica, Tianqi and other foods, which will help the healing of the fracture. Avoid blindly bearing weight too early, otherwise it may lead to obvious dislocation of the fracture and affect the recovery.
