Introduction

Although total hip replacement (THR) has been described as the operation of the century, there is still room for improvement. There is therefore continued effort for advanced implants and bearing surfaces, moreover so, for the younger patient with a longer life expectancy and increased needs.

Objectives

This prospective case-series study aims to present the preliminary, minimum three-years, results of a novel uncemeted stem, the Leader StemÃ’ (Vadin Implants Ltd, London, U.K.). The Leader StemÃ’ is a titanium, tapered stem for immediate three-point fixation. There is a metaphyseal porous-coating with titanium microspheres for bone in-growth. It has anti-rotational ribs in the metaphyseal - diaphyseal junction to promote initial stability and a grit blasted diaphyseal region for bone on-growth. The distal tip is polished and shortened to minimize thigh pain, while the whole design and concept is one to eradicate stress shielding.
