Synthes 204.855 3.5mm Cortex Screw Self-Tapping 55mm

Synthes 204.855 3.5mm Cortex Screw Self-Tapping 55mm

As a 3.5mm diameter screw with a substantial 55mm length, it is a foundational component of the Synthes Small Fragment System. This screw is designed to provide maximum structural stability in diaphyseal bone, making it a primary choice for treating fractures of the fibula, humerus, and tibia where extended reach is required.

• This geometry maximizes surface area contact, providing the high pull-out resistance required for long-bone stabilization.
• It allows for direct insertion following the drill pass, which is particularly beneficial in trauma scenarios where reducing anesthesia time is critical.
• Extended Reach (55mm): The 55mm length is ideal for bicortical fixation in the distal humerus or proximal tibia, or for anchoring plates in areas of thick cortical bone where standard small-fragment lengths fall short.
• Universal Plate Compatibility: The spherical head is precisely engineered to sit flush within the counter-sunk holes of Synthes DCP (Dynamic Compression Plates), LC-DCP (Limited Contact), and the non-locking portion of Small Fragment LCP Combi-holes.
• 316L Stainless Steel Biocompatibility: Cold-worked for high fatigue strength, the material is biologically inert and designed to withstand the cyclic loads encountered during the early stages of weight-bearing rehabilitation.
• Trauma Surgery: Fixation of diaphyseal fractures in the fibula, humerus, or radius/ulna where a longer screw is required for bicortical purchase.
• Plate Fixation: Serving as a "neutralization" or "compression" screw when used through 3.5mm small fragment plating systems.
• Malleolar Fixation: Stabilization of lateral malleolus fractures where a 55mm trajectory provides secure purchase in the syndesmosis region.
• Pelvic Reconstruction: Used in small-fragment pelvic sets for specific acetabular or pelvic ring fractures requiring deep cortical anchorage.
• Status: NEW — Factory Sealed & Sterile.
• Integrity: This implant is securely packaged within its original manufacturer's sterile peel-pouch. The packaging is intact, ensuring the product's sterility, material integrity, and full lot traceability for clinical implantation in 2026.
