Final answer:
Fractures typically require 3-6 months to fully heal, but individuals may wear a cast for about six weeks for simple fractures, with the exact healing time depending on various factors.
Step-by-step explanation:
The length of time required for fractures to fully heal can vary depending on the severity and location of the fracture, the age and health of the individual, and the treatment method employed. Generally, the body begins to repair a break soon after a fracture occurs. The area around the fracture becomes swollen and sore, and bone cells start to travel to the break site within a few days to rebuild the bone. It takes approximately two to three months before compact and spongy bone properly form at the break site, indicating that option B, 3-6 months, is the correct answer. However, for simple fractures, a person may wear a cast for about six weeks, with standard deviations showing variations in healing time. Ultimately, the healing process can involve steps such as formation of a fracture hematoma, formation of calli, replacement of cartilage by bone, and final bone remodeling.
