The Signature Evolve™ stem is manufactured from high nitrogen stainless steel. The system has 4 different offsets (35mm, 37.5mm, 44mm, 50mm) with 2 to 4 stem sizes per offset. This combination of offset/sizes and collarless design, allows the surgeon to adjust hip offset and leg length independent of each other.
It has a 12/14 taper connection for adaption to multiple head and taper sleeve options. The PMMA distal centraliser is intended to reduce point loading of the stem onto the cement, while allowing distal migration of the stem within the cement mantle.
