What is the expected timeline for hard callus formation during bone healing?

• A. 1-2 weeks
• B. 3-4 weeks
• C. 4-6 weeks
• D. 6 weeks to several months

Answer: (C)

Hard callus formation is a crucial phase in the bone healing process, occurring after the inflammatory stage and soft callus formation. This phase typically takes place approximately 4 to 6 weeks following the initial injury or fracture. During this timeframe, the body begins to replace the soft, cartilaginous callus formed initially with a hard callus made of woven bone, which is more robust and better suited to bear weight and withstand stress. This timeline can vary based on several factors, including the age of the individual, the type and location of the fracture, and the overall health of the patient. However, the general consensus in the literature supports that a hard callus is expected to begin forming within the 4 to 6 weeks window, indicating that this is the most accurate timeframe reflecting typical bone healing processes.
