摘要 当前治疗骨折的内固定材料基本上是金属,但是金属有几个明显的缺点需要克服:(1)金属内固定物过于坚硬,由于应力遮挡可形成骨质疏松、延迟愈合和再骨折;(2)骨折愈合后需再次手术取出;(3)一部分病人对金属敏感性大而产生免疫反应;(4)金属植入物有诱变性,可导致恶性肿瘤的发生。 基于这些原因,从六十年代开始许多发达国家就开始了可生物降解内固定物的研究,希望找到一种既能满足骨折固定的需要,又能生物降解的材料,以取代金属材料作为骨折内固定物。八十年代随着高分子聚合技术和塑料加工技术的发展,尤其是纤维增强技术的发展,可吸收骨折内固定物才有了很大的发展。目前临床应用最多的是自增强聚羟乙酸(self-reinforced polyglycolic acid,SR-PGA)、聚乳酸(poiylactic acid,SR-PLA)及其共聚物(polylactin 910),并以各种商品名在市场上销售,如Biofix、Vicryl、Phusiline及Ethipin等。
