Synthes 208.414 6.5mm Cannulated Screw 16mm Thread/95mm

Synthes 6.5mm Cannulated Screw | 16mm Thread | 95mm | 208.414

The Synthes 208.414 is a high-strength internal fixation implant engineered for stable anchorage and active interfragmentary compression in cancellous bone. As a 6.5mm diameter screw with a 95mm overall length and a 16mm partial thread, it is a foundational component of the Synthes Large Fragment Cannulated Screw System.

The partially threaded design (16mm thread length) is specifically engineered to function as a "lag screw." Because the threads only engage the far (distal) bone fragment while the smooth 79mm 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 and rotational stability in high-load anatomical regions.

Technical & Clinical Advantages

• Precision Guided Placement: The 2.9mm internal bore allows the screw to be delivered over a 2.8mm 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.

• Optimized Lag Compression: The 16mm thread length ensures that in most metaphyseal applications, the threads bypass the fracture line entirely to engage the far cortex. 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.

• 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 208.414 offers the high fatigue strength and corrosion resistance required to support physiological loads during the 2026 healing cycle.

Applications

• Femoral Neck Fractures: Providing stable, compressed fixation of the femoral head.

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

• Ankle Arthrodesis: Creating high-tension compression for joint fusions.

• Pelvic & Acetabular Surgery: Stabilization of sacroiliac disruptions or large iliac wing fragments where 95mm provides the necessary reach.

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