Synthes 208.411 6.5mm Cannulated Screw 16mm Thread 80mm

Synthes 6.5mm Cannulated Screw | 16mm Thread | 80mm Length | 208.411

The Synthes 208.411 is a robust internal fixation implant engineered for high-load applications in large bone structures. As a 6.5mm diameter cannulated screw, it features a hollow central core designed for precise placement over a pre-positioned 2.8mm guide wire. This system allows the surgeon to confirm perfect anatomical alignment via fluoroscopy before the screw is advanced, minimizing the risk of misplacement in critical zones such as the femoral neck or sacroiliac joint.

The 16mm Short Thread configuration is specifically engineered to create a powerful lag effect. By ensuring the 16mm of thread completely bypasses the fracture line to engage only the distal fragment, the smooth proximal shaft allows the screw head to draw the fragments together, generating high-pressure interfragmentary compression.

Technical & Clinical Advantages

• Guide-Wire Precision: The cannulated design is essential for minimally invasive (percutaneous) techniques. Once the guide wire trajectory is verified, the screw is driven over the wire, ensuring the final implant follows the exact intended path.

• Maximum Interfragmentary Compression: The 16mm thread length is optimized for "lagging" large fragments. Because the threads do not engage the proximal bone, the screw acts as a mechanical vice, pulling the distal bone toward the head for primary bone healing.

• Self-Drilling & Self-Tapping Tip: The distal tip features high-efficiency cutting flutes that allow the screw to be inserted directly over the guide wire in most cancellous bone applications, reducing operative steps and tourniquet time.

• High-Torque Hex Drive: The 4.0mm hexagonal recess provides the structural integrity required to transmit the high torque levels necessary for deep insertion into dense bone without stripping the screw head.

• 316L Stainless Steel Biocompatibility: Cold-worked for high fatigue resistance, this material is designed to withstand the significant cyclic loads associated with hip and pelvic fractures.

Applications

• Hip Surgery: Fixation of femoral neck fractures (intracapsular) using a parallel "inverted triangle" or "diamond" screw configuration.

• Pelvic & Acetabular Trauma: Stabilization of sacroiliac (SI) joint disruptions and vertical shear pelvic fractures.

• Knee Surgery: Compression of large tibial plateau fractures or distal femoral condyle fractures where a long reach is required.

• Ankle Arthrodesis: Large-joint fusions requiring significant compression across the joint space.
