The XL-Axenture Stem capitalizes on the excellent clinical results of proximal to distal tapered stem designs. The XL-AXENTURE system features a variety of stem designs that provide different methods of stem fixation, bone geometries and that also addresses different patients.
The porous-coated design promotes bone ingrowth and 3-dimensional interlocking between the implant and the bone. All XL-AXENTURE femoral stems are made from high-strength, titanium and feature a 3° proximal to distal taper. Parallel and longitudinally arranged flutes on the stems provide good axial and antirotational stability. The circulotrapezoidal neck of XLAXENTURE stems is smaller in the anterior/ posterior direction than most comparative stems.
