Fig. 2From: Optimal combined anteversion range for obtaining a wider range of motion without prosthetic impingement after total hip arthroplasty: a three-dimensional analysis studyImplant orientations are measured by superimposing the CAD models of the implants on postoperative CT images using Zed Hip. Yoshimine’s CA and Widmer’s CA were calculated from the implant orientation measurements. CAD, computer-aided design; CA combined anteversionBack to article page
