Synthes 204.865 3.5mm Cortex Screw Self-Tapping 65mm

Synthes 3.5mm Cortex Screw | Self-Tapping | 65mm Length | 204.865

The Synthes 204.865 is a high-load internal fixation implant engineered for secure anchorage in dense cortical bone. As a 3.5mm diameter screw with a substantial 65mm length, it is a specialized component of the Synthes Small Fragment System. This screw is designed for "long-track" stabilization where standard small-fragment lengths are insufficient, particularly in the proximal tibia, distal femur, and pelvic reconstruction.

The self-tapping distal tip features precision-machined cutting flutes that carve a matching thread path as the screw is advanced into a 2.5mm pilot hole. This eliminates the manual tapping step, which is a critical clinical advantage when navigating a 65mm trajectory, as it maintains superior tactile feedback and reduces operative time in complex trauma cases.

Technical & Clinical Advantages

• Optimized Cortical Pitch: The thread pattern is specifically calibrated for the dense mineral matrix of cortical bone. This geometry maximizes surface area contact, providing the high pull-out resistance required for stable fixation across wide anatomical planes.

• Self-Tapping Efficiency: By integrating cutting flutes into the screw tip, this implant reduces the number of surgical steps. It allows for direct insertion following the drill pass, which is particularly beneficial in "damage control" orthopedics where reducing anesthesia time is paramount.

• Extended Reach (65mm): The 65mm length is ideal for bicortical fixation in the proximal tibia or for providing "rafting" support under the articular surface in tibial plateau fractures.

• 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.

Applications

• Trauma Surgery: Fixation of diaphyseal and metaphyseal fractures in the tibia, humerus, or fibula where a longer screw is required for bicortical purchase.

• Pelvic Reconstruction: Used in small-fragment pelvic sets for specific acetabular or pelvic ring fractures requiring deep cortical anchorage.

• Tibial Plateau Fixation: Providing subchondral support (rafting) for articular fragments.

• Calcaneal Trauma: Stabilization of complex heel fractures where a 65mm trajectory provides secure purchase across the bone.
