Synthes 219.89 Threaded Washer for 3.0mm Cannulated Screws

Synthes Threaded Washer | For 3.0mm Cannulated Screws | 219.89

The Synthes 219.89 is a specialized orthopedic implant component designed to interface exclusively with the Synthes 3.0mm Cannulated Screw System. Unlike standard flat washers, this threaded washer features internal threads that allow it to be securely "locked" onto the screw shaft, providing a superior mechanical interface between the screw head and the bone surface.

This washer is essential in cases involving thin cortical bone or osteoporotic tissue, where a standard screw head might "sink" or pull through the bone surface during compression. By increasing the surface area of the screw head, the 219.89 ensures that interfragmentary compression is maintained without compromising the structural integrity of the near fragment.

• Quantity: 1 Each

Technical & Clinical Advantages

• Prevents Head Sinkage: In metaphyseal or osteoporotic bone, the 219.89 acts as a load-spreading buttress. It prevents the screw head from penetrating the thin cortex, ensuring that the tension generated by the screw is converted into effective interfragmentary compression.

• Threaded Locking Mechanism: The internal threads allow the washer to be pre-assembled or threaded onto the screw. This prevents the washer from "spinning" or becoming displaced during the high-torque final seating of the screw, a common issue with non-threaded washers in tight anatomical spaces.

• Low-Profile Geometry: Despite its increased surface area, the washer is designed with beveled edges to maintain a low profile. This is critical in hand and foot surgery to minimize soft-tissue irritation and protect adjacent tendons.

• Biocompatible 316L Stainless Steel: Forged from vacuum-melted surgical steel, the 219.89 provides the corrosion resistance and fatigue strength required for long-term internal fixation through the 2026 recovery cycle.

• System Integration: Perfectly calibrated for the Synthes 3.0mm system, ensuring a seamless fit with 3.0mm short-thread, long-thread, and fully-threaded cannulated screws.

Applications

• Hand & Wrist Surgery: Fixation of metacarpal and phalangeal fractures where the cortex is exceptionally thin.

• Foot & Ankle Surgery: Stabilization of metatarsal osteotomies and small-fragment fusions where high compression is required.

• Pediatric Orthopedics: Providing a broader base for fixation in young, soft bone to prevent hardware migration.

• Small Fragment Trauma: Used in periarticular fractures to distribute the load of a lag screw across a wider area of the articular surface.

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 surgical use.

• Sterilization Note: This device is provided in STERILE packaging. It is ready for immediate surgical use, provided the sterile barrier is uncompromised and the expiration date is verified per hospital protocol.
