The Rate of Correctly Planned Size of Digital Templating in Two Planes—A Comparative Study of a Short-Stem Total Hip Implant with Primary Metaphyseal Fixation and a Conventional Stem

(1) Background: Preoperative templating is mainly conducted on an anteroposterior pelvic overview X-ray. For short stem hip arthroplasty, the choice of optimal size especially crucial to avoid complications. Thus, study aimed determine if there increased rate correctly planned sizes using two radiological planes. (2) Methods: 50 patients with a conventional and 100 total arthroplasty were analyzed. Without knowing implanted size, three independent orthopedic surgeons performed digital templating: once only lateral view in addition. (3) Results: The (+/−1 compared inserted size) one plane was 86.3% ± 9.5% 88.4% 6.0% arthroplasty. By adding view, 89.9% 12.0% for group 89.4% 9.8% (p > 0.1). (4) A potential positive effect preoperative additional X-ray implants may be suggested based results this study, which did, however, not reach statistical significance.
