Detailed explanation-1: -Most fractures heal in 6-8 weeks, but this varies tremendously from bone to bone and in each person based on many of the factors discussed above. Hand and wrist fractures often heal in 4-6 weeks whereas a tibia fracture may take 20 weeks or more.
Detailed explanation-2: -When a bone breaks or fractures (broken and fractured means exactly the same thing), healing of the bone usually takes a few months to occur. A bone is considered healed or “united” when it is strong enough to allow normal activities. Depending on many factors, this can take as little as 4 weeks or as long as 6 months.
