INTRODUCTION

Trabecular Titaniumâ„¢ is an innovative material characterised by an high open porosity and composed by multi-planar regular hexagonal cells. It is not a traditional coating and its tri-dimensional structure has been studied to optimise osteointegration. Furthermore, it has excellent mechanical properties, as a very high tensile and fatigue resistance and an elastic module very similar to the that of the trabecular bone. The aim of this study is to evaluate the osteointegration and bone remodelling measuring the longitudinal pattern of change in BMD around a cementless acetabular cup made from Trabecular Titaniumâ„¢ (Delta TT cup, Lima Corporate, Italy) in primary total hip arthroplasty (THA).

METHODS

Dual-energy x-ray absorptiometry (DEXA) analysis, radiographic evaluation on standard AP and lateral views and clinical evaluation with Harris Hip Score (HHS) and SF-36 were performed at 1 week, 3, 6, 12 months after surgery.
