Femoral Neck Section Of The Acquisition And The Establishment Of Coordinate

Objective: to determine the use of mimics 3 d reconstruction technology research and the research method of the section, the femoral neck identify femoral neck and shaft and perpendicular to the new cutting head and neck axle load, cross section of the femoral neck and drawing in the coordinate system.Selection methods:1. The affiliated hospital of shandong university of TCM in October 2010 to October 2015 period scan CT data of hip joint,the selection no obvious fractures under the age of 65, right hip bone disease cases in 30 cases of men. 2. The application of the right femur mimics software to reconstruct a 3 d model at the bottom of, application of Murphy fixed axis method to determine the femoral neck and shaft in three-dimensional space, and perpendicular to the new cutting head and neck axle load, get the femoral neck in cross section.(3) in head and neck axle load points for the origin, with the origin and the femoral big tuberosity attachment as the x axis a coordinate system, and in the heart of the coordinate system of the femoral neck section drawing. 4. Graphic long axis and short axis, income measures are used to describe the cross section graph.Results: 1.the shape of the section, the femoral neck and drawing in the coordinate system. Integrated image long axis of the minimum of((?)±S):34.46±1.93 mm, minimum short axis is((?)±S):27.17±1.74 mm.2.Crosssection shape close to the triangle.Conclusion: 1. To determine the application mimics 3 d reconstruction technology research femoral neck section of the research methods. 2. The femoral neck section is a diagonal line similar to the shape of a triangle.3. establish a coordinate system can directly express the femoral neck section. 4.Three-dimensional positioning laid the foundation for internal fixation.
