Assignment task:
How does bone heal itself after it has fractured? Imagine a patient fell and fractured the diaphysis of her humerus in a car accident. It is a simple fracture - the bone did not break through the skin or damage any other soft tissue. The bone fragments were not displaced, so her clinician applied a cast to immobilize her upper limb.
Bone tissue has a remarkable ability to heal. Assuming this patient does not have any complications that could impair the healing process (e.g. osteoporosis), describe the 4 steps of the fracture repair, including the cells involved and their function.
