Synthes 219.98 Washer 7.0mm

Synthes Washer | 7.0mm Outside Diameter | 219.98

The Synthes 219.98 is a specialized orthopedic accessory designed to optimize the mechanical interface between a screw head and the bone surface. With a 7.0mm outside diameter, this washer is primarily utilized with 2.7mm, 3.5mm, and 4.0mm screws.

In orthopedic fixation, the primary role of the washer is to increase the surface area of the screw head. This prevents the head from "sinking" or "diving" into soft, cancellous bone—a common challenge in metaphyseal fractures or osteoporotic bone. By distributing the compressive load across a wider area, the 219.98 ensures that interfragmentary compression is maintained without compromising the structural integrity of the near cortex.

• Quantity: 1 Each

Technical & Clinical Advantages

• Load Distribution: By expanding the footprint of the screw head to 7.0mm, the washer significantly reduces the pressure exerted on the underlying bone. This is essential for achieving stable "lag screw" fixation in thin cortical areas or where bone quality is diminished.

• Low-Profile Design: The 219.98 is engineered with a slim vertical profile and beveled edges. This minimizes hardware prominence, reducing the risk of soft-tissue irritation or tendon impingement in areas with minimal subcutaneous cover, such as the distal fibula or medial malleolus.

• Concave Seating Geometry: The internal aspect of the washer is contoured to match the spherical underside of standard Synthes screw heads. This ensures a self-centering, stable fit that prevents the screw from toggling or shifting under load.

• 316L Stainless Steel Biocompatibility: Forged from cold-worked, vacuum-melted surgical steel, the washer offers high fatigue strength and maximum corrosion resistance, ensuring long-term stability within the physiological environment of 2026.

• Prevention of "Tuliping": In high-torque applications, the washer provides a rigid backstop that prevents the screw head from deforming the bone entry site, ensuring the "lag effect" is fully realized.

Applications

• Metaphyseal Fractures: Stabilization of fractures in the proximal or distal tibia and humerus.

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

• Hand & Wrist Surgery: Supplemental use with 2.7mm or 3.5mm screws in distal radius reconstruction.

• Geriatric Trauma: Essential for maintaining compression 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 typically 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 7.0mm diameter remains perfectly flat and the finish remains pristine.

• Fast Dispatch: Ships within 1 business day.
