<p>This record contains raw data related to article &quot;Clinical and&nbsp;radiological outcomes of&nbsp;an&nbsp;uncemented metaphyseal short&nbsp;stem at&nbsp;minimum 10&nbsp;years of&nbsp;follow‑up: a&nbsp;prospective observational study&quot;</p> <p>Abstract</p> <p><strong>Purpose:&nbsp;</strong>There is growing interest around short stems as they provide a less invasive approach for total hip arthroplasty preserving bone stock for a possible revision surgery if required. The main purpose of this work was to assess the long-term performance of an uncemented metaphyseal short stem in terms of survival rate and in addition its clinical and radiological outcomes.</p> <p><strong>Materials and methods:&nbsp;</strong>From January to December 2010, we prospectively enrolled all consecutive patients undergoing primary total hip arthroplasty with an uncemented metaphyseal short stem in our institution with a minimum follow-up of 10 years. The radiographic features investigated were the varus-valgus stem orientation, areas of osteolysis and radiolucencies, stress shielding, and heterotopic calcifications. The clinical outcomes were measured using the HHS.</p> <p><strong>Results:&nbsp;</strong>A total of 163 patients (172 hips) were finally included and the measured survival rate at 10 years was 99.6%. The average HHS increased from 55.0 preoperatively to 97.8 at the last follow-up (p &lt; 0.0001). Among them, 137 patients (164 hips) were also available for radiographic assessment. Mild varus malalignment was observed in 40% of cases and remained stable in the serial X-rays and was not associated with step loosening. Mild stress shielding was observed around 13 stems (9%) and moderate only around 3 implants.</p> <p><strong>Conclusion:&nbsp;</strong>In conclusion, the uncemented metaphyseal short stems showed excellent survival and clinical results at 10 years and at a radiographical level very low stress shielding was observed; moreover, besides the high frequency of varus alignment the implanted stems was not associated with revision surgery or with worse clinical outcomes.</p> <p><strong>Keywords:&nbsp;</strong>Long-term; Outcomes; Short stem; THA.</p>
