A new water setting light plastic plaster material, Crystona, is presented and its plaster room characteristics compared with plaster of Paris. Plaster of Paris is considered better as the "acute fracture splinting material" in the Accident Service setting. Crystona, however, has considerable advantages as the "dynamic bracing material" in the post-acute fracture period and is demonstrated in the functional bracing of femoral shaft fractures. An improved functional cast brace design is presented, the "Knee Hinge Cylinder Brace" with a simple waist belt suspension to a hinged tube cast without the foot in the treatment of distal half femoral fractures. Using Crystona and the cylinder brace design, the cast weight has been reduced by half and the functional limb bracing improved with free mobilization of the knee, ankle and foot. The prescription, application technique and early clinical experiences are presented.
一种新型的水凝轻质塑料石膏材料——Crystona被推出，并将其石膏室特性与巴黎石膏进行了比较。在事故服务环境中，巴黎石膏被认为是更好的“急性骨折固定材料”。然而，Crystona作为急性骨折后期的“动态支撑材料”具有相当大的优势，并在股骨干骨折的功能支撑中得到了体现。本文介绍了一种改进的功能性管型支具设计，即“膝关节铰链圆柱支具”，它采用简单的腰带悬挂在无足部的铰链管型石膏上，用于治疗股骨远端一半的骨折。使用Crystona和圆柱支具设计，管型重量减轻了一半，并且通过膝关节、踝关节和足部的自由活动改善了肢体的功能支撑。文中还介绍了其处方、应用技术及早期临床经验。
