The fifth metatarsal fracture walking early may have the following hazards: 1. local pain or swelling, because after the fracture is not completely healed, the fracture is unstable to stimulate the periosteum causing pain, or even bleeding, causing swelling. 2. the fracture does not heal, because after the fracture requires 4-6 weeks of stability, the bone scab will slowly form, the fracture will slowly stabilize, 6-8 weeks after the fracture is basically healed, 12 weeks after the fracture is completely healed. 3. The fracture will heal basically in 6-8 weeks and completely after 12 weeks, so early walking may cause the fracture not to heal. 3. It may cause delayed healing or deformed healing, because after early walking, the fracture will be displaced or misaligned, and then it may appear long and crooked, that is, deformed healing, or it may even appear delayed healing when it is supposed to grow and live for 3 months, but it does not grow and live.
