4 major events in bone repair

Bone Fractures

Bone Repair step one: Hematoma is formed—

a blood filled swelling caused from blood vessels rupturing when bone breaks

Bone Fractures

Bone Repair step two: Fibrocartilage callus forms—

Cartilage, bone and collagen fibers laid down Acts as a splint Closes the gap

Bone Fractures

Bone Repair step three: Bony Callus formation—

Osteoblasts and osteoclasts come to the area Fibrocartilage is replaced by spongy bone

Bone Repair step four: Bone Remodeling—

In response to mechanical stress Strong permanent bone formed at site of injury
