Trabecular Titanium™ is a highly porous biomaterial with a regular hexagonal cell structure, which has shown excellent mechanical properties. Several 89 patients (91 hips) underwent primary THA with DELTA-TT cups (Lima Corporate) between 2009 and 2010. There were 46 (52%) men and 43 (48%) women, with a median (IQR) age of 67 (57–70) years and a median (IQR) BMI of 26 (24–29) kg/m2. Right side and left side were affected in 44 (48%) and 47 (52%) cases, respectively. Underlying pathology was primary osteoarthritis in 80 (88%) cases, osteonecrosis in 5 (6%), post-traumatic osteoarthritis in 3 (3%), developmental dysplasia of the hip in 2 (2%) and oligoarthritis in 1 (1%). BMD was determined by DXA using DeLee and Charnley 3 Regions of Interest (ROI) at 7 days, 3, 6, 12 and 24 months. Clinical evaluation (Harris Hip Score, HHS), patient health status survey (SF-36) and radiographic assessment were performed preoperatively and at the same time-points. Data were analyzed using non-parametric tests (Introduction
