Sequestrum
The pathological process is as follows:
infection in the bone leads to an increase in intramedullary pressure due to inflammatory exudates
the periosteum Within the bone itself, the haversian canals become blocked with scar tissue, and the bone becomes surrounded by thickened periosteum.

Endosteum
It is called the periosteum, or the periosteal surface. During bone growth, the width of the bone increases as osteoblasts lay new bone tissue at the periosteum.

Formation of periosteum
The perichondrium becomes the periosteum. The periosteum contains a layer of undifferentiated cells (osteoprogenitor cells) which later become osteoblasts.

Iliac fascia
the inner aspect of the iliac crest; inferiorly and laterally, it extends into the thigh to unite with the femoral sheath; medially, it attaches to the periosteum medially, to the linea terminalis of the lesser pelvis, where it is continuous with the periosteum.

Intramembranous ossification
The periosteum is formed and bone growth continues at the surface of trabeculae. The primary center of ossification is the area where bone growth occurs between the periosteum and the bone.

Codman triangle
instead of dimpling, the periosteum tears away and provides ossification on the second edge of the triangle. The advancing tumour displaces the periosteum away from the bone medulla.
