– See: – Ficat Classification – Enneking’s Stages of Osteonecrosis – Discussion: – combination of osteoclastic resorption and new bone formation in revascularized areas creates x-ray appearance of mottled density; – when collapse of segment of necrotic bone occurs, the compression of more bone into smaller … Read more
