A number of new synthetic orthopaedic splinting materials, all claiming substantial advantages over the traditional plaster-of-Paris, have been introduced in recent years. However, although their properties have been extensively measured in the laboratory, little has been documented concerning their performance in clinical use. This study was therefore initiated as a comparative evaluation of the clinical characteristics and ease of use of these relatively expensive materials in the fabrication of below-knee weight-bearing casts. The study encompassed nine materials--seven based on water-activated polyurethanes, one thermoplastic and plaster-of-Paris, and involved a total of 203 patients. It was concluded that plaster-of-Paris should be used for all routine splinting applications, but that in cases in which cast weight, cast bulk, or the time to bearing weight is important, a synthetic material, chosen principally on the basis of cost, is indicated.
近年来，已经推出了许多新型合成矫形夹板材料，所有这些材料都声称比传统的熟石膏具有显著优势。然而，尽管它们的性能已在实验室中进行了广泛测量，但关于它们在临床使用中的表现却鲜有记录。因此，本研究旨在对这些相对昂贵的材料在制作膝下承重石膏时的临床特征和易用性进行比较评估。该研究涵盖了九种材料——七种基于水活化聚氨酯、一种热塑性材料和熟石膏，共涉及203名患者。研究得出的结论是，熟石膏应用于所有常规夹板应用，但在石膏重量、石膏体积或开始承重时间很重要的情况下，建议选择主要基于成本的合成材料。
