Bone Fractures to know

​The first stage of healing is Hematoma. This is an important stage because the blood clot that serves as a mold for new bone growth. The second stage includes a lot of new cells migrating to the area. We will call it Granulation Tissue which leads to the 3rd stage we will call callus(the callus usually set by the 3rd week). There is a lot of excess bone when the callus hardens so the 4th stage is callus removal. This can take months yo years. This is done by osteoclasts.

Multiple Choice

If a hematoma is lost or damaged what do you think would happen?

• Damage to a hematoma improves circulation.
• Loss or damage to a hematoma can cause bleeding and complications.
• Loss of a hematoma leads to increased blood flow.
• A hematoma will heal without any issues.
