Fracture Non-Union (Visit this link)
Clevelnad Clinic Patient Information Every fracture carries the risk of failing to heal and resulting in a nonunion. While nonunions can occur in any bone, they are most common in the tibia, humerus, talus, and fifth metatarsal bone. Several factors contribute to a non-union. If the bone ends that are fractured have been stripped away from the blood vessels that provide them with nutrition, they will die. As a result, the bone ends cannot contribute to new healing, and a nonunion is more likely. Without a good blood supply and growth of new blood vessels, no new bone will form and the fracture cannot readily heal.
