Experiments were conducted in rabbits comparing polyurethane foam-covered implants with otherwise identical smooth silicone gel implants. Using five objective methods of measurement of capsular contracture, no significant difference could be identified. The foam-covered implants consistently developed capsular contracture, although in most cases this was of mild degree and would not have been clinically significant. In the two foam-covered implants with hard contractures, there was no evidence of hematoma or separation of the foam.
在兔子身上进行了实验，比较了覆盖聚氨酯泡沫的植入物与其他方面相同的光滑硅胶凝胶植入物。使用五种测量包膜挛缩的客观方法，未发现显著差异。覆盖泡沫的植入物始终会出现包膜挛缩，尽管在大多数情况下程度较轻，在临床上不具有显著性。在两个出现严重挛缩的覆盖泡沫的植入物中，没有血肿或泡沫分离的迹象。
