Abstrakt: Background: The purpose of our investigation was to compare a digital templating system to conventional templating techniques when preoperatively planning for total hip arthroplasty.Methods: We included 18 consecutive patients with primary osteoarthritis undergoing uncemented total hip arthroplasty in our study. At separate sittings, we independently conducted preoperative templating. They performed the templating using hard-copy radiographic films and traditional hard-copy prosthetic overlays on a radiograph view box. They then repeated templating using a digital technique at a computer workstation with specially developed software. We used kappa statistical analysis to evaluate intra-and interobserver variability of both techniques. We also examined correlation of template measurements with final component selection.Results: Intra-and interobserver variability was satisfactory for both templating techniques. There was no significant difference in the performance of the 2 techniques in predicting final component selection during surgery.Conclusion: Digital preoperative templating is as reliable as conventional templating techniques.
