One-half inch thick polyurethane foam is recommended for use in postoperative casts to avoid complications seen with postoperative swelling. The polyurethane is placed over the operative area, over the dorsum of the foot, and the anterior surface of the leg. The use of polyurethane foam in the postoperative cast not only avoids the necessity of having to split the cast in many instances but the foam also constitutes a compression dressing. If splitting of the postoperative cast should become necessary, the foam protects the skin.
建议在术后石膏中使用半英寸厚的聚氨酯泡沫，以避免术后肿胀引发的并发症。聚氨酯放置在手术区域、足背和小腿前表面。在术后石膏中使用聚氨酯泡沫不仅在许多情况下避免了石膏切开的必要，而且该泡沫还起到了压迫敷料的作用。如果术后石膏有必要切开，泡沫可保护皮肤。
