This study was based on data from the Finnish Arthroplasty Register. From 1990 to 1999, 33,154 primary hip arthroplasties were performed in Finland. Only periprosthetic fractures treated by a revision arthroplasty were registered. The six most used femoral components were compared using survival analysis and Cox's regression model. The incidence of periprosthetic fractures was calculated separately for the years 1990-1994 and 1995-1999. The incidence in the first period was greater than in the latter. Survival analysis and Cox's regression model showed that gender, prosthesis type and age were of no significance as risk factors for periprosthetic fractures.
本研究基于芬兰关节成形术登记处的数据。1990年至1999年期间,芬兰共进行了33154例初次髋关节置换术。仅登记了通过翻修关节成形术治疗的假体周围骨折。使用生存分析和考克斯回归模型对六种使用最多的股骨组件进行了比较。分别计算了1990 - 1994年和1995 - 1999年假体周围骨折的发生率。第一阶段的发生率高于后一阶段。生存分析和考克斯回归模型表明,性别、假体类型和年龄作为假体周围骨折的危险因素并无统计学意义。
