Synthes 204.675 3.5mm Pelvic Cortex Screw Self-Tapping 75mm

Synthes 3.5mm Pelvic Cortex Screw | Self-Tapping | 75mm | 204.675

The Synthes 204.675 is a high-precision internal fixation implant specifically engineered for the unique anatomical and biomechanical requirements of the pelvic ring. As a 3.5mm diameter screw with a 75mm length, it is a foundational component of the Synthes Pelvic Reconstruction System, designed for procedures where standard cortical screws are too short to achieve secure purchase.

The self-tapping design features precision-machined cutting flutes at the distal tip. While a 2.5mm pilot hole is required to establish the trajectory, the screw cuts its own internal threads as it advances. This ensures a high-friction "custom fit" between the screw and the bone, maximizing pull-out resistance—a critical factor in the high-stress environment of pelvic trauma.

Technical & Clinical Advantages

• Optimized for Pelvic Corridors: The 75mm length is ideal for stabilizing the iliac wing, anterior column, or posterior wall of the acetabulum. It provides the necessary depth for bicortical purchase across common pelvic fracture lines.

• Superior Cortical Purchase: The shallow, tightly pitched threads are designed to grip the dense cortical bone of the pelvis. This provides exceptional stability for plate fixation or "lagging" bone fragments together.

• Self-Tapping Efficiency: By integrating the tapping function into the screw tip, the 204.675 reduces the number of instrument passes in the surgical field. This minimizes the risk of contamination and decreases total anesthesia time for the patient.

• High-Torque Drive Interface: The 2.5mm hexagonal socket provides a robust interface for controlled torque application. This allows for secure final seating without the risk of head stripping, even when driving through dense bone over a long trajectory.

• 316L Stainless Steel Biocompatibility: Forged from vacuum-melted surgical steel, the 204.675 offers the high fatigue strength and corrosion resistance required for long-term internal fixation through the 2026 recovery cycle.

Applications

• Pelvic Ring Disruptions: Stabilization of sacroiliac fragments or iliac wing fractures.

• Acetabular Fractures: Securing the columns or walls of the acetabulum where 75mm provides optimal depth.

• Pelvic Osteotomies: Maintenance of alignment in corrective pelvic surgeries (e.g., Periacetabular Osteotomy).

• Trauma Reconstruction: Providing lag compression or positional support for multi-fragmentary pelvic trauma.

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 as a NON-STERILE implant. It MUST be properly cleaned and sterilized via validated steam autoclave protocols in accordance with hospital 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 precision-machined 75mm shaft remains perfectly straight and the distal self-tapping flutes remain pristine.

• Fast Dispatch: Ships within 1 business day.
