Cementless Tapered Femoral Stem Stability | Conformity | Versatility

Stability Designed to preserve bone and promote improved proximal loading. Conformity Optimal geometry defined by global CT data for a patient matched solution. Versatility A seamless range of stem sizes with an improved proximal:distal size ratio.

Stability Corin’s TriFit TS™ cementless femoral stem is manufactured from forged titanium alloy for strength and biocompatibility. Based on an optimised, clinically proven, bi-planar geometry1,2, TriFit TS™ is designed to be a bone conserving stem. The reduced lateral proximal shoulder helps preserve as much of the greater trochanter as possible whilst the distal portion similarly helps to minimise the amount of cancellous bone removed from the femur. A 50° neck cut preserves bone in the calcar region and increases proximal support for the implant medially. An optimised anterior-posterior...

Head offset Small increments and two offset options (standard and lateralised) form a seamless range of sizes. The proximal-to-distal ratio and distal sweep is also designed to promote proximal loading and prevent distal hang-up, which may reduce the risk of subsidence as seen with other stems of this philosophy6. Additionally the triple taper from anterior to posterior is designed to aid proximal loading and optimise stem stability. Lightweight compact modular instrumentation offers the surgeon a range of approach-specific options for certain procedural steps. Corin TriFit TS™ Competitor...
