Brenneis M, Braun S, van Drongelen S, et al. - In this study, the accuracy and reliability of three-dimensional (hipEOS) and common digital two-dimensional (TraumaCad) templating with a special focus on stem morphology were compared. Researchers randomized a total of 51 patients who had undergone total hip arthroplasty into two groups. They conducted preoperative planning on 23 patients with hipEOS (3D) and on 28 patients with TraumaCad (2D) planning software. The data imply that in comparison with digital templating with TraumaCad software, 3D templating with hipEOS software has good overall reliability and may have a better planning accuracy of short stem prostheses. The findings demonstrate that assuming that the number of implanted short stem prostheses will further increase in the coming years, more precise planning with the 3D technique can contribute to improving surgical outcomes.
