Synthes 214.568 4.5mm Cannulated Screw Partially Threaded/68mm

Synthes 4.5mm Cannulated Screw | Partially Threaded | 68mm | 214.568

The Synthes 214.568 is a high-precision internal fixation implant engineered for stable anchorage and active interfragmentary compression in cancellous and metaphyseal bone. As a 4.5mm diameter screw with an extended 68mm length, it is a foundational component of the Synthes 4.5mm Cannulated Screw System, designed for procedures requiring significant depth and mechanical compression.

The partially threaded (lag) design is specifically engineered to draw two bone fragments together. By ensuring the threads only engage the "far" bone fragment while the smooth proximal shaft glides through the "near" fragment, the screw head generates high-tension compression across the fracture line. This is the gold standard for promoting primary bone healing in metaphyseal fractures.

Technical & Clinical Advantages

• Precision Guided Placement: The 1.75mm internal bore allows for accurate delivery over a 1.6mm guide wire. This enables the surgeon to verify the trajectory via fluoroscopy before final seating—essential for percutaneous applications in the hip, pelvis, or ankle.

• Controlled Interfragmentary Compression: The smooth 68mm shaft prevents "thread-locking" in the near fragment. This ensures that the rotational force of insertion is converted entirely into compressive force at the fracture site, promoting rapid biological union.

• Self-Drilling & Self-Tapping Tip: Engineered with distal cutting flutes, this screw eliminates the need for separate drilling and tapping steps in most cancellous bone applications. This reduces operative time and minimizes instrumentation requirements on the surgical field.

• High-Torque Drive Interface: The 3.5mm hexagonal socket provides a robust interface for high-torque insertion, minimizing the risk of head stripping or "cam-out" during final seating in dense cortical bone.

• 316L Stainless Steel Biocompatibility: Forged from vacuum-melted surgical steel, the 214.568 offers the high fatigue strength and corrosion resistance required for long-term internal fixation throughout the 2026 recovery cycle.

Applications

• Ankle & Foot Surgery: Fixation of large malleolar fractures and calcaneal osteotomies.

• Metaphyseal Trauma: Stabilization of large avulsion fractures or periarticular fragments in the proximal or distal tibia.

• Pelvic & Acetabular Surgery: Providing stable compression in pelvic ring disruptions where a 4.5mm diameter and 68mm length offer optimal shear strength and depth.

• Pediatric Orthopedics: Precise fixation of epiphyseal fractures where the guide wire protects the growth plate during planning.

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.
