Potentialities of 3D-Visualization in Preoperative Planning of Primary and Revision Total Hip Arthroplasty

Abstract

A variant of preoperative planning for revision interventions on a hip joint named “Method of layer by layer 3D visualization of the defect zone” is suggested. The method is realized via three consecutive steps with the ultimate aim to obtain data on the real acetabular defect geometry and bone tissue density. Using that method 9 patients (mean age 60±2 years) with pelvic bones defects were examined preoperatively. Based on the evaluation results of bone tissue condition in the defect zone the model and size of individual augment within the limits of weight bearing bone were corrected, the points of augment and acetabular component fixation were determined.
