Intro

Our collaboration with Professor K. Zweymüller, who has decades of experience with cementless hip prostheses, has produced the dual taper SL-PLUS stem. Together with the intuitive instrumentation, the SL-PLUS represents a system that is accommodating and forgiving. The SL-PLUS provides unsurpassed primary stability, which along with a tailor made surface, to support long-term survivorship.

Initial stability is critical for a cementless prosthesis. The SL-PLUS, with its double taper rectangular design, achieves initial stability in two ways. The double taper locks into a secure axial position, while the rectangular form anchors the stem rotationally. Once initial stability has been achieved, the materials used and the surface architecture promotes secondary stability. The SL-PLUS is forged from highly biocompatible titanium alloy. This material more closely matches the elasticity of bone to reduce stress shielding. Then, it is grit blasted to produce a surface structure that may promote osseointegration.

From the patient's and surgeon's prospective, the SL-PLUS is a strong option. All surgical instrumentation is intuitive and extremely flexible, reducing surgical time and complications. Because the site is broached instead of reamed, bone is not removed but impacted into the periprosthetic region. Beacuse it is cementless, no additional foreign substance is needed.
