BACKGROUND Fractures of the proximal femur epiphysis are problematic for state health care because they are associated with severe medical and social problems and high morbidity and mortality *** To model the potential risk of hip fracture via femur geometric *** Seventy educational cadaveric femurs from people aged 14 to 80 years,10 X-ray images from the records of the Human Anatomy Department and 10 X-ray images from the Department of Traumatology,Orthopedics and Disaster Surgery of Sechenov University,were *** parameters of the fractured bone were measured using images captured with a Canon d60 *** projection values of the proximal epiphysis of the cadaveric femurs and geometric parameters of the bones shown in the X-ray images were measured with Autodesk software(AutoCAD 2018).Analysis of the video frames showing bone rotation reveal that the greater trochanter can be inscribed in a parallelepiped,where one of the faces is parallel to the plane of view in the frontal standard projection and is *** angle of bone rotation obtained by turning the cube corresponded to the angle measured with the second *** reliable method of calculating the rotation of the bone relative to the anterior projection was employed in subsequent *** geometric parameters of the femur were measured using X-ray images according to the proposed *** The geometric parameters of 70 femurs were analyzed,and correlation coefficients were *** measurement results were compared with those reported by other *** potential influence of femur geometry on force distribution in the proximal epiphysis of the femur was described,and a 2-dimensional model of the femur epiphysis associated with minimal neck fracture risk was *** assessment of the geometric parameters of the femoral epiphysis indicated the greatest risk of a varus fracture of the neck if the angle of the minimal resistance zone(AMRZ)

引用

Chinese Nursing Research 2016年第3期3卷 113-116页

作者： Chun-Li Wu Mei Lin Ying Bao Xiang Wang Nursing College Huzhou University Huzhou Zhejiang 313000 China The First Affiliated Hospital of Huzhou University Huzhou Zhejiang 313000 China

This paper describes the de？nition of venous thromboembolism and introduces to personalized venous thromboembolism risk assessment tools overseas. Thoughts are given on the development, amendment,application and validation of these tools. The paper provides a reference for building personalized venous thromboembolism risk assessment tools in China.
