When is the slower setting time of Plaster of Paris most clinically useful?

Answer

During initial reduction requiring meticulous molding

The slower setting time associated with Plaster of Paris, which requires hours to achieve a full cure compared to the rapid setting of fiberglass, is deliberately exploited by orthopedic surgeons in specific, demanding situations. This extended working window is crucial when performing an initial reduction—the manual process of realigning fractured bone segments. The clinician benefits from having more time to meticulously manipulate, contour, and mold the still-pliable material precisely around the intricate contours of the injury site. This precision molding is vital for ensuring perfect initial alignment of complex fracture patterns before the cast hardens permanently, guaranteeing maximum stability from the outset, a level of deliberate manipulation that faster-setting synthetic wraps do not easily permit.
