Let's assume we have a type 1 closed fracture in the coronoid process:
The treatment is to immobilize that joint in plaster. However, the patient should also limit their movement.
I wonder why is that, when by definition the joint is immobilized? As long as there is no pressure on the surrounding bones (e.g. carrying objects with that arm) I though movement of irrelevant bones (e.g. walking) will not affect the healing process. Yes, there are swinging if the arm is hung before chest, but it's the movement of the whole arm, and the joint is still fixed.
Is there any factor that affect the healing process, beside immobilizing the fractured location?
A minor question: if arm swinging is the problem, then would eliminating that swing by attaching the whole arm to the body be fine?
