Primary prosthetic replacement in elderly patients with displaced intracapsular fracture of the femoral neck has been used during the last few years with encouraging early results. The prosthetic device preferred has been Christiansen's endoprosthesis. During the past year a new type with separable plastic head and metallic cap has been used. This modification has resulted in the occurrence of a previously unknown complication, a separation of these two parts, necessitating reoperation and insertion of a new head piece. The possible mechanisms causing this separation are discussed.
在过去几年中，对老年股骨颈囊内移位骨折患者进行一期假体置换，取得了令人鼓舞的早期效果。最常用的假体装置是克里斯蒂安森人工关节。在过去一年里，使用了一种新型的、带有可分离塑料头和金属帽的假体。这种改进导致了一种以前未知的并发症的出现，即这两个部分的分离，这就需要再次手术并植入一个新的头部部件。本文讨论了导致这种分离的可能机制。
