This study assessed the accuracy of preoperative digital templating for a second-generation cementless stem compared with its first-generation design. A prospective cohort of 100 consecutive patients who had undergone a primary total hip arthroplasty using a new second-generation cementless stem was compared with the prior 100 hips that had received the first-generation stem. The authors believe that the second-generation stem may allow equal or more accurate digital templating compared with its predicate design.
本研究评估了第二代非骨水泥型股骨柄与第一代设计相比，术前数字模板的准确性。将连续100例使用新型第二代非骨水泥型股骨柄进行初次全髋关节置换术的患者作为前瞻性队列，与之前接受第一代股骨柄的100例髋关节进行比较。作者认为，与前代设计相比，第二代股骨柄可能允许同等或更准确的数字模板。
