Plaster of Paris (PoP) has been the predominant treatment option for most acute and chronic orthopedic conditions. Water immersion significantly decreases the PoP bandage strength. Moreover, concerns have been raised about the possibility of breaks in PoP splints and cast failures once solid. The current study was designed to account for the increase in weight associated with increased PoP layers. The authors hypothesized that by controlling for weight variation as layers increased, they could determine the number of layers of PoP bandage that truly results in optimal mechanical properties. They assessed whether adequate plaster weight control while increasing layers could improve the mechanical properties of the splint. [. 2022;45(1):e57-e61.].
熟石膏（PoP）一直是大多数急性和慢性骨科疾病的主要治疗选择。水浸会显著降低 PoP 绷带的强度。此外，人们还担心一旦 PoP 夹板和石膏变硬，就有可能出现断裂和失效。本研究旨在考虑与 PoP 层增加相关的重量增加。作者假设，通过控制随着层数增加的重量变化，他们可以确定 PoP 绷带的层数，从而真正获得最佳的机械性能。他们评估了在增加层数的同时，是否可以通过适当控制石膏重量来改善夹板的机械性能。[2022；45（1）：e57-e61]。
