Reply to comments on the article: Bone remodelling around the Metha short stem in total hip arthroplasty: A prospective dual-energy X-ray absorptiometry study

摘要

We thank Mr. Diamond and Mr. McAlinden for their interest in our article [1]. We agree that a comparison of the two stems might be of interest, but only at first glance. During the study we learned that a direct comparison of the DEXA results of the two stems would lead to a misunderstanding of the implants. The Bicon-tact stem (BBraun, Aesculap, Tuttlingen, Germany) is a straight, standard stem which is implanted in an older population when compared to the Metha stem. Both stems follow a different femoral loading philosophy. Deeper resection for the Bicontact straight stem and the greater diaphyseal loading, with a larger proximal plasma sprayed surface leads to stabilisation in the intertrochanteric area [2, 3].
