Article Synopsis
- - The study examines the effectiveness of highly-porous 3D-printed titanium acetabular cups in total hip arthroplasty for patients with rheumatoid arthritis, a group typically facing higher risks and complications compared to those with osteoarthritis.
- - Researchers followed 37 rheumatoid arthritis patients over an average of 3.2 years, noting significant improvements in hip function and pain, as measured by the Harris hip score and VAS, with no acetabular complications reported.
- - Results indicate that these 3D-printed implants achieved excellent osseointegration and positive clinical outcomes, suggesting their viability for use in patients with rheumatoid arthritis undergoing hip surgery.
Femoral Neck Preservation and Diaphyseal Invasion Comparing a Calcar-Metaphyseal Short Stem with its Homonymous Standard Femoral Stem. A Radiographic Study.

June 2023
Background: We aim to compare the preoperative planning radiographs of 50 patients in whom both a short stem and its homonymous standard version were programmed, focusing on the preservation of the neck and the invasion of the femoral shaft. The secondary objective was to evaluate the 50 preoperative radiographs with the 50 postoperative radiographs in which the short stem was implanted, measuring the real invasion of the diaphysis and the real preservation of the femoral neck.
Material And Methods: We measured cut level at the femoral neck and diaphyseal invasion in 50 preoperative x-rays where an Alteon Neck Preserving Stem (ANPS) was templated and we compared it with 50 preoperative x-rays where an Alteon Taper Wedge Stem (ATWS) was templated.
Introduction: Total hip arthroplasty in young patients has evolved in recent decades, and the use of short stems in young adult patients has been gaining popularity. The restitution of the biomechanics of the hip is a primary requirement to determine the future success of total hip replacement, and even more so in young adults who present the particularity of having a high functional demand and a long life expectancy.
Objective: The aim of this prospective study was to evaluate the learning curve and initial clinical-radiological outcomes of the Alteon Neck Preserving Stem™ (ANPS) (Exactech, Gainesville, FL, USA) with a minimum of 2 years follow up.
