Synthes 206.028 4.0MM Cancellous Bone Screw Fully Threaded /28MM

Synthes 4.0mm Cancellous Bone Screw | Fully Threaded | 28mm Length | 206.028

The Synthes 206.028 is a precision-engineered internal fixation screw specifically designed for engagement in cancellous (spongy) bone. As a 4.0mm diameter screw with a fully threaded profile, it is optimized for applications where the entire length of the screw must engage the bone to provide stable fixation. The 28mm length makes it an essential component for the stabilization of larger bone fragments, particularly in the metaphyseal regions of long bones where cortical thickness is minimal.

Forged from high-grade 316L stainless steel, this screw features deep, widely spaced threads that provide superior pull-out resistance in less dense bone architectures compared to standard cortical screws.

Technical & Clinical Advantages

• Optimized Cancellous Pitch: The widely spaced, deep threads are specifically engineered to "grip" the porous matrix of cancellous bone. The fully threaded design ensures that the screw provides consistent anchorage along its entire 28mm length.

• Superior Stability in Metaphyseal Bone: By maximizing the thread-to-bone surface area, the 206.028 provides a high degree of stability, which is critical in preventing fragment displacement during the early biological stages of bone healing.

• Hexagonal Drive Precision: The 2.5mm hexagonal recess allows for the transmission of high insertion torque without the risk of "cam-out" or stripping the screw head, ensuring secure final seating.

• Low-Profile Spherical Head: The head is designed to sit flush within the counter-sunk holes of Synthes small fragment plates (e.g., 3.5mm DCP or LCP systems) or directly against the bone surface with a washer to prevent subsidence.

• 316L Stainless Steel Biocompatibility: Cold-worked for high fatigue strength, the material is biologically inert and designed for long-term implantation in load-bearing environments.

Applications

• Trauma Surgery: Fixation of large metaphyseal fragments in periarticular fractures (e.g., tibial plateau, distal radius, or pilon fractures).

• Orthopedic Reconstructive Surgery: Stabilization of osteotomies and arthrodesis sites in the foot, ankle, and hand.

• Plate Fixation: Serving as a "neutralization" screw when used through 3.5mm LCP or DCP plating systems in regions of predominantly cancellous bone.

• Malleolar Fixation: Providing stable anchorage for medial or lateral malleolar fractures where cortical density may be insufficient for standard screws.
