Since introduction of the prosthetic joint replacement numerous design modifications have taken place. Some were successful other were given up after short time. During almost twenty years now in joint arthroplasty of the hip components made of A12 03-ceramics--ball and/or socket--are used. Many papers have reported about the results of these implants. One of the possible complications described in the literature is the breakage of the ceramic component(s). Since April 1981 we have implanted over 500 cementless prosthesis of the hip in combination with a ceramic ball. In one patients we observed a breakage of the head two years after implantation. We will describe the story of this case and discuss possible reasons for this complication in reference to the literature.
自从人工关节置换术问世以来，出现了许多设计上的改进。有些改进取得了成功，而有些则在短时间后被放弃。在近二十年里，髋关节置换术中一直使用由氧化铝陶瓷制成的部件——球和/或臼。许多论文报道了这些植入物的结果。文献中描述的一种可能并发症是陶瓷部件的断裂。自1981年4月以来，我们已经植入了500多个无骨水泥髋关节假体，并搭配陶瓷球。在一名患者中，我们观察到植入两年后球头发生了断裂。我们将讲述这个病例的情况，并结合文献讨论这种并发症可能的原因。
