. Plaster of paris is used for setting fractured bone. Why?

Best Answer

Plaster of paris is the major constituent of surgical bandages that are used for setting fractured bones. Before applying on fractured bone it is made wet with water. The bandage is then immediately spread on the broken part. As a result of hydration, it changes into  Gypsum which keeps the bones in position that have been made straight by the doctor before applying plaster. Slow calcification takes place on the broken part and the gap is slowly filled. In this way broken bones once again unite to form a single piece.
