Synthes 209.890 7.3mm Cannulated Screw 32mm Thread/90mm

Synthes 7.3mm Cannulated Screw | 32mm Thread | 90mm | 209.890

The Synthes 209.890 is a high-strength internal fixation implant engineered for stable anchorage and active interfragmentary compression in large bone structures. As a 7.3mm diameter screw with a 90mm overall length and a 32mm partial thread, it is a primary component of the Synthes Large Fragment Cannulated Screw System.

The partially threaded design (32mm thread length) is specifically engineered to function as a "lag screw." Because the threads only engage the far (distal) bone fragment while the smooth 58mm proximal shaft glides through the near fragment, the screw head draws the two pieces together. This results in high-tension compression across the fracture line, which is essential for primary bone healing in high-load anatomical regions like the femoral neck or pelvis.

Technical & Clinical Advantages

• Precision Guided Placement: The 3.2mm internal bore allows the screw to be delivered over a pre-placed guide wire. This enables the surgeon to confirm the trajectory via fluoroscopy before the screw is seated, facilitating minimally invasive percutaneous placement and reducing soft-tissue disruption.

• Superior Lag Compression: The 32mm thread length is calibrated to ensure that in many metaphyseal applications, the threads bypass the fracture line entirely to engage the far fragment. This maximizes the compressive force generated by the screw head against the near cortex.

• Self-Drilling & Self-Tapping Tip: The distal tip features precision-machined cutting flutes that eliminate the need for separate drilling and tapping steps in cancellous bone. This reduces operative time and minimizes thermal damage to the bone during the 2026 surgical cycle.

• High-Torque Hexagonal Drive: The 4.0mm hexagonal socket provides a robust interface for controlled torque application. This ensures secure final seating and easy removal, even after long-term implantation.

• 316L Stainless Steel Biocompatibility: Forged from vacuum-melted surgical steel, the 209.890 offers the high fatigue strength and corrosion resistance required to support physiological loads during the healing process.

Applications

• Femoral Neck Fractures: Providing stable, compressed fixation of the femoral head (typically using a three-screw inverted triangle pattern).

• Pelvic & Acetabular Fractures: Stabilization of sacroiliac disruptions or large iliac wing fragments.

• Tibial Plateau Fractures: Stabilizing large articular fragments and providing a buttress against axial loads.

• Slipped Capital Femoral Epiphysis (SCFE): Precise, guided stabilization of the epiphysis in pediatric or adolescent patients.

• Large Joint Arthrodesis: Creating high-tension compression for ankle or knee fusions.

Condition & Quality Assurance

• Status: NEW — Factory Sealed.

• Integrity: This 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.
