The BW High-Spray Emery Femoral Stem is a technologically advanced, cementless implant designed to maximize bone-implant contact and accelerate biological fixation. The defining feature of this stem is its proprietary High-Spray Emery coating, which utilizes a specialized plasma spray technique to create a highly textured, rough surface finish that mimics the roughness of emery cloth. This aggressive surface finish significantly enhances the initial mechanical press-fit stability within the femoral canal and provides an optimal porous scaffold for bone ingrowth (osseointegration). Constructed from high-fatigue strength Titanium Alloy, the stem's proximal geometry is often designed as a tapered wedge to maximize load transfer to the strong metaphyseal bone, making the TOOLMED BW Stem an ideal solution for active patients seeking durable, long-term hip reconstruction.

Product Description
The specialized High-Spray Emery texture provides a highly abrasive and macro-porous surface, maximizing the friction and contact area between the implant and the bone for robust initial scratch-fit and stability.
The aggressive porosity and pore size distribution of the coating are optimized to facilitate faster and deeper bone tissue ingrowth compared to conventional plasma spray coatings, achieving quicker biological fixation.
Designed with a specific taper and overall geometry to achieve an immediate, stable mechanical lock (press-fit) into the femoral canal, which is essential to prevent micromotion that could hinder bone ingrowth.
The stem core is manufactured from high-strength Titanium Alloy, providing excellent fatigue resistance and ensuring the structural integrity required to withstand lifelong cyclical loading.
Used in patients with good bone quality where long-term cementless fixation and early weight bearing are desired, typically for osteoarthritis or avascular necrosis.
Ideal for younger patient populations where the superior long-term durability and resistance to aseptic loosening associated with biological fixation are prioritized.

The BW High-Spray Emery Femoral Stem is a specialized, cementless stem for hip replacement that gets its name from its uniquely rough surface. The "Emery" texture, created via a high-velocity plasma spray process, is designed to be highly abrasive and porous. This aggressive surface finish is key to achieving a powerful initial press-fit and providing the optimal biological stimulus for bone cells to grow directly onto and into the implant, securing it for life.
It is used in primary Total Hip Arthroplasty for patients who have sufficient bone stock to allow for a reliable press-fit. Its ability to achieve rapid and secure biological fixation makes it particularly well-suited for orthopedic centers that prioritize long-term, cementless hip replacement outcomes, especially for active individuals.
The primary advantage is enhanced primary stability and rapid osseointegration. The abrasive emery-like surface generates greater friction at the bone-implant interface upon insertion. This superior initial stability is crucial for minimizing micromotion, which is the main inhibitor of bone ingrowth, thereby accelerating the process of long-term biological fixation.
The stem's biomechanics are based on the principle of proximal load transfer. The tapered, high-friction proximal region of the stem takes the majority of the load, transferring it directly to the dense, cancellous bone in the upper femur. The distal stem is often highly polished or less porous to avoid distal fixation, thereby preventing complications associated with distal stress shielding.
The technique requires precise preparation of the femoral canal using specialized broaches that are slightly undersized relative to the final stem dimensions. The stem is then impacted into the canal using strong forces to achieve the necessary tight mechanical lock (scratch-fit). This tight fit is verified by intraoperative fluoroscopy or tactile feedback before final component assembly.
The aggressive initial stability achieved by the high-spray emery surface often allows for accelerated rehabilitation. Postoperative protocols typically encourage early protected weight-bearing, as physiological loading stimulates the bone to grow into the highly porous coating, strengthening the biological fixation.
The BW High-Spray Emery Femoral Stem represents a high-performance choice in cementless hip arthroplasty. By optimizing surface technology for aggressive initial fit and enhanced bone ingrowth, the stem provides surgeons with a reliable and durable foundation for reconstructing the hip joint, offering patients the best potential for long-term stability and functional recovery.
The "Emery" surface is created using a high-velocity plasma spray technique where titanium powder is melted and sprayed onto the stem surface, creating a rough, highly porous layer optimized for bone ingrowth.
This stem is primarily designed for primary total hip arthroplasty in patients with good bone stock who can achieve a strong press-fit. Revision surgeries typically require longer, modular stems (like the Revision Femoral Stem).
Yes, the aggressive surface requires slightly higher impaction forces for insertion, but this effort is necessary to achieve the vital initial stability (scratch-fit) that leads to successful biological fixation.
The risk of micromotion is minimized due to the stem's tapered geometry and the high-friction emery coating, which locks the implant securely into the bone immediately after insertion, allowing the biological fixation process to begin successfully.
Yes, it features a standard Morse taper connection, making it compatible with all standard modular femoral heads (Ceramic or Cobalt-Chrome) from the TOOLMED system and other compatible manufacturers.
