The Proxima Short Stem from Depuy is a proximally loading short stem hip prosthesis made of forged titanium alloy, with a Duofix™ porous coating and hydroxyapatite surface coating. It is available in nine sizes with standard and high-offset variants. The paper by Toth (1) gives several...

The Accolade femoral stem from Stryker is an uncemented, proximally coated, collarless femoral component manufactured from Stryker’s proprietary beta titanium alloy, TMZF. TMZF has a modulus of elasticity closer to that of bone than Ti-6Al-4V alloy. The proximal coating is 50 micron thick...

The Silent hip is a tapered press-fit, textured implant designed to sit in the femoral neck without contacting the lateral cortex. It was launched in 2009 and remains in clinical trials. Links to clinical trials Multi-Centre Study to Assess the Long-Term Safety and Efficacy of the Silent...

The Corail stem has been in clinical use since the 1980s. It is a fully hydroxy-apatite coated (150 micron thickness) non-porous forged titanium alloy stem. The design includes a proximal trapexoidal cross section, intended to resist axial/torsional stresses and promote initial stability, and a...

The CFP (Collum Femoris Preserving) stem is a collared, curved short stem device designed for minimally invasive implantation. It is a modification of the stem originally designed by Pipino in the early 1980s, the design aims of which included rotational stability by triplanar fixation,...
