Bone Pathologies

• Simple fractures usually take about 6-8 weeks to
  heal, although larger or elderly bones take
  longer.
• There are four main steps to bone repair
• The blood vessels ruptured in a broken bone cause
  a blood filled swelling called a haematoma at the
  site of the fracture
• 2) A cartilage callus forms in place of the
  haematoma. It acts to splint the broken bone
• 3) A bony callus forms, replacing the cartilage
  with a callus made of spongy bone
• 4) The bony callus remodels in response to stress
  placed on it, forming a strong, permanent patch
  at the fracture site
