Synthes 219.972 Washer 6.5mm

Synthes Washer | 6.5mm Outside Diameter | 219.972

The Synthes 219.972 is a high-precision orthopedic implant component designed to optimize the mechanical interface between a screw head and the bone surface. With a 6.5mm outside diameter, this washer is a specialized accessory typically utilized with 2.7mm, 3.5mm, and 4.0mm screws.

In orthopedic fixation, the primary role of the washer is to increase the footprint of the screw head. This prevents the head from "sinking" or "diving" into soft, cancellous bone—a common challenge in metaphyseal fractures, periarticular reconstructions, or osteoporotic bone. By distributing the compressive load across a wider area, the 219.972 ensures that interfragmentary compression is maintained without compromising the structural integrity of the near cortex.

Technical & Clinical Advantages

• Enhanced Load Distribution: By expanding the screw head's surface area to 6.5mm, the washer significantly reduces the local pressure exerted on the bone. This is essential for achieving stable "lag screw" fixation in areas where bone density is compromised.

• Low-Profile Design: The 219.972 is engineered with beveled edges and a slim vertical profile. This minimizes hardware prominence, which is critical for reducing soft-tissue irritation in anatomical sites with minimal subcutaneous cover, such as the malleoli or the distal radius.

• Self-Centering Concave Seating: The internal geometry is precision-contoured to match the spherical underside of standard Synthes screw heads. This ensures a stable, coaxial fit that prevents the screw from toggling or shifting under physiological load.

• 316L Stainless Steel Biocompatibility: Forged from vacuum-melted surgical steel, the washer offers high fatigue strength and maximum corrosion resistance, ensuring long-term mechanical reliability within the body throughout the 2026 healing cycle.

• Preservation of Cortical Integrity: In high-torque applications, the washer acts as a rigid backstop that prevents the screw head from deforming the entry site, ensuring the intended compression is fully realized across the fracture line.

Applications

• Metaphyseal Trauma: Stabilization of fractures in the proximal or distal tibia, humerus, or femur.

• Foot & Ankle Surgery: Providing stable compression in malleolar fractures or calcaneal osteotomies where the bone cortex may be thin.

• Hand & Wrist Surgery: Supplemental use with 3.5mm or 4.0mm cancellous screws in distal radius reconstruction.

• Geriatric Trauma: Essential for maintaining stable fixation in osteoporotic bone where screw heads are prone to "pull-through."

Condition & Quality Assurance

• Status: NEW — Factory Sealed.

• Integrity: The implant is securely housed within its original manufacturer's packaging. Both inner and outer seals are intact, ensuring full material integrity and suitability for clinical use.

• Sterilization Note: This device is provided as a NON-STERILE implant within the packaging. It MUST be properly cleaned and sterilized via validated steam autoclave protocols in accordance with facility guidelines and Synthes’ Instructions for Use (IFU) prior to clinical implantation.

• Professional Standards: With over 25 years of experience in orthopedic logistics, Primis Medical ensures all Synthes implants are handled and stored to maintain their mechanical and chemical precision.

Shipping & Handling

• Secure Logistics: Shipped in protective packaging to ensure the 6.5mm diameter remains perfectly flat and the finish remains pristine.

• Fast Dispatch: Ships within 1 business day.
