Mid-term results of a new-generation calcar-guided short stem in THA: clinical and radiological 5-year follow-up of 216 cases

ConclusionsThe rate of stem revision (0%) at the mid-term follow-up was remarkable and indicates the principle of using a calcar-guided short stem as being a safe procedure. However, signs of bone-remodelling, indicating some amount of stress-shielding, must be acknowledged at 5 years depending on stem alignment and type of anchorage.Level of evidenceIV, Prospective observational studyTrial registration German Clinical Trials Register, DRKS00012634, 07/07/2017 (retrospectively registered)
