In a prospective study of patients with fractures of the proximal femur from a defined population it was found that age, mental test score, type of residence, place of injury and hospital of admission were all significantly associated with the likelihood of survival to six months. When these factors were taken into account no additional association between outcome and recorded associated disease, grade of surgeon operating, cigarette smoking, type of operation or social class was demonstrable. These findings have implications for the design of controlled trials of different types of treatment for fractures of the proximal femur.
在一项针对特定人群中股骨近端骨折患者的前瞻性研究中发现，年龄、心理测试得分、居住类型、受伤地点及入院医院均与六个月生存率显著相关。当考虑这些因素时，未发现结局与记录的相关疾病、手术医生级别、吸烟、手术类型或社会阶层之间存在额外关联。这些发现对股骨近端骨折不同治疗类型的对照试验设计具有启示意义。
