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 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...
متن کاملThromboprophylaxis after total hip replacement
The risk of secondary haematologic complications such as deep vein thrombosis or pulmonary embolism increases significantly when a transient period of hypercoagulability is induced after total hip replacement (THR). A number of drug-based anticoagulant approaches are available to modulate this risk, but the optimal length of therapy for such approaches remains unclear. The literature was review...
متن کاملCup re-enforcement for recurrent dislocation after hip replacement.
Recurrent dislocation after total hip replacement usually demands revision. Ahnfelt (1986) reported 626 disbocations of which 79 (1 1.2%) dislocated twice, 33 (5.1%) three times and 40 dislocated (6.6%) four times. We now report the results of treating 1 3 cases of recurrent dislocation by fixing an additional sector to the posterior rim ofthe acetabular component after Charnley total hip repla...
