No, the bony callus is primarily composed of spongy (cancellous) bone. It forms during the healing process of a bone fracture and helps stabilize and repair the bone. The bony callus eventually remodels into compact bone over time.
The formation of the bony callus in fracture repair is followed by remodeling. During remodeling, the bony callus is gradually replaced by mature bone tissue, restoring the shape and strength of the fractured bone. This process can take several weeks to months to complete.
No, the diaphysis of a long bone is primarily composed of compact bone, not spongy bone. The compact bone surrounding the central medullary cavity provides strength and support to the bone, while spongy bone is typically found at the ends of long bones.
Following the formation of the bony callus in fracture repair, the next phase involves the remodeling of the callus into a stronger, more organized bone structure. This process can take several months to years, during which the callus is gradually replaced by compact bone, and the bone returns to its original shape and strength. Additionally, the surrounding muscles and tissues may also adapt to support the healed bone. Overall, the remodeling phase is crucial for restoring the functionality and integrity of the bone.

There are four stages in the repair of a broken bone: 1) the formation of hematoma at the break, 2) the formation of a fibrocartilaginous callus, 3) the formation of a bony callus, and 4) remodeling and addition of compact bone.
When a bone is broken, specialized cells called osteoblasts and chondrocytes work together to repair it. Initially, blood clots form around the break and a soft callus of fibrous tissue is created. Over time, this callus hardens into new bone tissue, restoring the structure and strength of the bone.

The metatarsal heals through a natural process of bone regeneration that involves inflammation, repair, and remodeling. Initially, a fracture triggers inflammation, leading to the formation of a hematoma and a soft callus. Over time, this soft callus is replaced by a hard callus as new bone tissue forms, followed by the remodeling phase where the bone is reshaped and strengthened. Proper rest, immobilization, and sometimes physical therapy support this healing process.
