this study analyzed factors influencing prosthetic hip function after total hip replacement surgery (THR) including the initial acetabular fracture type, patient age, and the acetabular reconstruction component.
a total of 45 patients with secondary arthritis due to acetabular fracture and THR were prospectively selected from our total hip arthroplasty register between July 1999 and December 2005. The initial acetabular fracture was classified according to the AO system and the statistical analysis of the preoperative and postoperative Harris hip score (HHS) was correlated with age, type of fracture and acetabular reconstruction component.
of the fractures 44 could be classified and 39 patients were included in the study. Median follow-up period was 15 months. HHS increased on average from 35 to 91. Only type C fractures showed statistical relevance and age had no influence on the median increase in HHS (53-55). Most important was the preoperative HHS and the restoration of proper hip anatomy and rotational alignment.
patient age and injury severity influenced the preoperative function and hence the HHS after THR; however, these factors had no influence on the individual increase in the HHS.
本研究分析了全髋关节置换术（THR）后影响人工髋关节功能的因素，包括初始髋臼骨折类型、患者年龄和髋臼重建组件。
1999年7月至2005年12月期间，从我们的全髋关节置换术登记册中前瞻性地选取了45例因髋臼骨折继发关节炎并接受THR的患者。初始髋臼骨折根据AO系统进行分类，并对术前和术后的Harris髋关节评分（HHS）进行统计分析，将其与年龄、骨折类型和髋臼重建组件相关联。
44例骨折可分类，39例患者纳入研究。中位随访期为15个月。HHS平均从35分提高到91分。只有C型骨折显示出统计学相关性，年龄对HHS的中位增加值（53 - 55）没有影响。最重要的是术前HHS以及髋关节正常解剖结构和旋转对线的恢复。
患者年龄和损伤严重程度影响术前功能，从而影响THR后的HHS；然而，这些因素对HHS的个体增加值没有影响。
