06 - Bones & Skeletal Tissues - Bone Repair

During this phase of bone healing the blood vessels in and around the bone are torn and bleeding occurs

• Hematoma formation

• Fibrocartilaginous callus formation

• Bony callus formation

• Remodeling

During this phase of bone healing the excess material on the sides of the bone is removed and compact bone is laid down to reconstruct the shaft of the bone

• Hematoma formation

• Fibrocartilaginous callus formation

• Bony callus formation

• Remodeling

This is the stage in which collagen fibers start to span the break and connect the broken bones.

• Hematoma formation

• Fibrocartilaginous callus formation

• Bony callus formation

• Remodeling

At the end of this stage of bone healing the final structure resembles the original unbroken bone

• Hematoma formation

• Fibrocartilaginous callus formation

• Bony callus formation

• Remodeling

This acts as the body’s natural splint

• Hematoma formation

• Fibrocartilaginous callus formation

• Bony callus formation

• Remodeling

The initial even following a bone fracture is:

• Hemorrhage and hematoma formation

• Endochondral ossification

• Remodeling

• Ossification of internal callus

• Formation of granulation tissue

Healing of a fracture, even after severe damage, depends on the survival of:

• The circulatory supply and the cellular components of the Endosteum and Periosteum

• The bone’s mineral strength and its resistance to stress

• Osteoblasts within the spongy and compact bone

• External callus which protects the fractured area

This cell lays down new bone and helps repair damage.

• Osteoblast

• Osteoclast

• Osteocyte

• Osteobuddies
