A method to calculate the acetabular cup anteversion after total hip replacement based on 3D coordinate system
Aim: To explore an accurate method to calculate acetabular cup anteversion after total hip arthroplasty. Method: 1) A 3D coordinate system was established with the center of the hip joint rotation center base as coordinate center. The acetabular exit plane and Pettersson formula acetabular anteversion and Riten Pradhan formula acetabular anteversion and acetabular true anteversion were drawn; 2...
متن کاملAn analysis of the best method for evaluating anteversion of the acetabular component after total hip replacement on plain radiographs.
Several radiological methods of measuring anteversion of the acetabular component after total hip replacement (THR) have been described. These studies used different definitions and reference planes to compare methods, allowing for misinterpretation of the results. We compared the reliability and accuracy of five current methods using plain radiographs (those of Lewinnek, Widmer, Liaw, Pradhan,...
متن کاملA New Method for Measuring the Angle of Hallux Valgus
Objectives. The aim of this study is to introduce a new way and assign its reliability and validity in measuring the angle of hallux valgus. Methods. In this method, we have proceeded to introduce a simple way for measuring the angle of hallux valgus by using ruler and mathematical formulas. For doing this study, we selected 25students and measured their angle of hallux valgus with new way ...
متن کاملA new tool for measuring cup orientation in total hip arthroplasties from plain radiographs.
Orientation of the hip cup is important in total hip arthroplasties. Orientation includes abduction (inclination) and anteversion. Anteversion can be considered as true (anatomic) and planar (radiographic) anteversion. Some measurement methods either are too complicated or are less precise. We developed a new protractor to measure cup orientation using postoperative anteroposterior radiographs ...
متن کاملCup Anteversion/tilt Effects on Dislocation Propensity for Small-head-size Total Hip Replacements
Malposition of the acetabular component is a leading cause of dislocation in total hip arthroplasty (Woo, 1982). The two most influential surgeon-controlled variables are thought to be abduction (tilt) and anteversion of the cup. Empirically, while 30-50° of tilt and 5-25° of anteversion is felt to be a “safe-zone” (Morrey, 1992), dislocation nevertheless remains a disturbingly frequent occurre...
