The aim of this study was to analyze the factors affecting the outcomes after surgical treatment of acetabular fractures.
Between January 2000 and December 2012, 106 patients with acetabular fractures were treated with open reduction and internal fixation. We performed a retrospective cohort study to analyze the factors which may influence a patient's prognosis after surgical treatment of an acetabular fracture. The factors examined included age, femoral head injury, fracture type, dislocation, initial displacement, delay to injury-related surgery (in days), and quality of reduction. Additionally, we investigated clinical and radiological outcomes, as well as the development of osteoarthritis.
Patients included 85 males (80.2%) and 21 females (18.8%) with a mean age of 50.4 (17-78) years. The mean follow-up period was 2.6 (1-10) years. In a univariable regression analysis, quality of reduction, age, and initial displacement were significantly associated with radiological and clinical outcomes. In a multivariable regression analysis, quality of reduction (P<0.001) and initial displacement (P=0.001) were found to be factors predictive of clinical and radiological outcomes. Additionally, the quality of reduction (P=0.005) was found to be predictive of osteoarthritis development.
Study results indicated that the quality of reduction was the most important factor influencing the prognosis of patients with acetabular fractures.
本研究旨在分析髋臼骨折手术治疗后影响疗效的因素。
2000年1月至2012年12月期间，106例髋臼骨折患者接受切开复位内固定治疗。我们进行了一项回顾性队列研究，以分析髋臼骨折手术治疗后可能影响患者预后的因素。所检查的因素包括年龄、股骨头损伤、骨折类型、脱位、初始移位、受伤至手术的延迟时间（天数）以及复位质量。此外，我们还调查了临床和影像学结果以及骨关节炎的发生情况。
患者包括85例男性（80.2%）和21例女性（18.8%），平均年龄为50.4岁（17 - 78岁）。平均随访期为2.6年（1 - 10年）。在单变量回归分析中，复位质量、年龄和初始移位与影像学和临床结果显著相关。在多变量回归分析中，发现复位质量（P<0.001）和初始移位（P = 0.001）是临床和影像学结果的预测因素。此外，发现复位质量（P = 0.005）是骨关节炎发生的预测因素。
研究结果表明，复位质量是影响髋臼骨折患者预后的最重要因素。
