Avenir ® Femoral Hip System

Avenir Hip System Intuitive and Reproducible During its decade of experience in the bone compaction stem market, the Avenir Hip System has helped surgeons experience flexible, and reproducible surgeries, reportedly even for first users. The specific broaches were designed to allow a precise, balanced and intuitive femoral preparation to help reduce the risk of subsidence and foster long-term stability while offering surgeons straightforward operative techniques. • Offers Intraoperative Flexibility Cementless and cemented options are included within a single instrumentation platform. •...

Avenir Cementless Stem Surface Finish and Macro Structure Meant To Last Long-term stability being the primary objective, the Avenir stem design consists of a straight bone compaction body with a proprietary scheme of ridges in all planes and a double-layered coating. Macro-structure designed to facilitate distribution of loads Metaphysis - Medial and Frontal Planes Angled ridges designed to ease proper seating of the stem on the calcar Diaphysis - Frontal Plane Vertical Ridges Designed to facilitate stem insertion and increase bone contact surface Lateral Plane Vertical Ridges Increase bone...

Ti-6Al-4V Forged titanium alloy, Protasul®- 64 WF supporting a double layered coating of vacuum plasma sprayed commercially pure titanium under a thin layer of hydroxyapatite Fully Polished Neck Designed to help reduce wear debris 12/14 Taper Compatible with most of the Zimmer Biomet heads* Double-layered coating designed for long-term stability The undercoat of commercially pure titanium vacuum plasma spray (CP-Ti) allows the application of a thin hydroxyapatite top coat. This combination may help reduce the release of third body particles and associated risk of aseptic loosening. Forged...

Avenir Cemented Stem Line-to-Line Broaching & Cementing Techniques The Avenir cemented stem offers a consistent combination of a line-to-line broaching technique with a line-to-line cementing technique. Sizing Rationale The Avenir brand includes cementless and cemented stems in standard and lateral versions with a constant CCD angle of 135°. In the frontal plane, the size increment is smaller for small sizes than between larger sizes allowing fine adjustment in small femoral canals. Each range includes 9 sizes, from 129 to 177 mm stem length. Cross-Section Rectangular with smoothed edges...

Highly Polished, forged Stainless Steel (Protasul® S-30) Helps limit the release of wear debris, while the flexural strength of stainless steel helps prevent early debonding of the cement-stem interface and subsequent stem loosening.1,2 Fully Polished Neck Designed to help reduce wear debris Taper 12/14 Compatible with most of the Zimmer Biomet heads* Cementing Technique: Line-to-Line or French Paradox A femoral canal filling stem induces a thin cement mantle sometimes incomplete with direct cortical contact in particular areas. This technique has shown good long-term results by protecting...

Instrumentation Bone Compaction System with a Unique Broach Design The precise size match between Avenir Hip System rasps and final implant combined with its instrumentation platform including both cemented and cementless options, help surgeons experience straightforward, intuitive and reproducible surgeries. Not a 100% Bone Compaction stem, for good reasons! The Avenir Hip System offers a balance between cancellous and cortical bone contacts. The rasp design favors compacted cancellous bone in the proximal and distal portions of the femoral canal and cortical contact in the metaphysis....

Accurate line-to-line sizing between rasp and implant allows reproducible surgery and helps reduce the risk of subsidence. The size match between the rasp and the final implant is so precise that all resection lines on the bone, rasp and implant should be aligned. This technical feature helps reduce the risk of subsidence and allows for good management of leg length.
