Synthes 212.110 3.5MM Locking Screw Self Tapping W/ Stardrive Recess 28MM

Synthes 3.5mm Locking Screw | Self-Tapping | StarDrive™ | 28mm Length | 212.110

The Synthes 212.110 is a high-performance internal fixation implant engineered for Locking Compression Plate (LCP) systems. As a 3.5mm diameter screw with a 28mm length, it is a foundational component of the Synthes Small Fragment LCP System. Unlike standard cortex screws, this locking screw features a threaded conical head that mechanically locks into the plate's threaded hole, creating a "fixed-angle" construct. This provides superior stabilization in osteopenic bone and complex comminuted fractures where traditional screw-to-bone purchase is compromised.

Technical & Clinical Advantages

• Fixed-Angle Stability: The threaded head locks into the plate, transforming the plate-screw assembly into a single rigid unit. This eliminates the need for the plate to be compressed against the bone to maintain stability, preserving the periosteal blood supply.

• StarDrive™ Recess (T15): The StarDrive™ interface allows for higher torque transmission compared to traditional hexagonal drives. It significantly reduces the risk of "cam-out" or stripping the screw head, ensuring reliable insertion and easier removal if needed.

• Self-Tapping Efficiency: Precision-machined cutting flutes at the tip allow the screw to carve its own thread path in a 2.8mm pilot hole. This eliminates the separate tapping step, saving operative time and maintaining high tactile feedback.

• 316L Stainless Steel Biocompatibility: Cold-worked for high fatigue strength, the material is biologically inert and designed to withstand the cyclic loads encountered during early functional rehabilitation.

• Increased Core Diameter: At 2.9mm, the core is thicker than a standard 3.5mm cortex screw, providing increased resistance to bending and shear forces within the locking construct.

Applications

• Trauma Surgery: Fixation of diaphyseal and metaphyseal fractures in the radius, ulna, and fibula using LCP technology.

• Osteopenic Bone Fixation: Providing stable anchorage in elderly patients where bone mineral density is reduced.

• Comminuted Fractures: Bridging complex fractures where the screw cannot rely on traditional "lag" compression for stability.

• Forearm Reconstruction: Stabilization of osteotomies or non-union repairs requiring rigid internal fixation.
