Synthes 212.123 3.5mm Locking Screw Self Tapping w/ Stardrive Recess 55mm

Synthes 3.5mm Locking Screw | Self-Tapping | StarDrive™ Recess | 55mm Length | 212.123

The Synthes 212.123 is a high-performance internal fixation screw engineered for use with the Synthes Small Fragment Locking Compression Plate (LCP) System. As a 3.5mm diameter locking screw, it features a threaded head that mechanically locks into the plate's threaded hole, creating a "fixed-angle" construct. This provides superior angular stability compared to conventional screws, making it the clinical standard for the fixation of osteoporotic bone and complex comminuted fractures.

At a length of 55mm, this screw is specifically suited for spanning wider bone diameters, such as the distal femur, proximal tibia, or pelvic reconstructions, where deep bicortical engagement is required for maximum stability.

Technical & Clinical Advantages

• Fixed-Angle Stability: The threaded head locks into the plate, effectively turning the plate and screw into a single rigid construct. This prevents "toggle" and secondary loss of reduction, which is critical in zones of high mechanical stress.

• StarDrive™ Torque Transmission: The StarDrive™ (T15) recess provides a significantly higher surface area for driver engagement compared to traditional hexagonal drives. This allows for higher torque transmission, reduces the risk of "cam-out," and virtually eliminates screw head stripping during insertion or removal.

• Self-Tapping Efficiency: The distal tip features specialized cutting flutes that allow the screw to cut its own threads as it is advanced. This eliminates the need for separate tapping, reducing operative time and decreasing the risk of thermal injury to the bone.

• Reduced Bone-to-Plate Compression: Because the screw locks into the plate, it does not rely on pressing the plate against the bone to achieve stability. This preserves the periosteal blood supply, facilitating faster biological healing.

• 316L Stainless Steel Integrity: Forged from cold-worked surgical steel, the 212.123 offers the high fatigue resistance necessary to withstand the cyclic loads of weight-bearing during the recovery period.

Applications

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

• Complex Reconstruction: Pelvic and acetabular fractures requiring long-reaching bicortical fixation.

• Osteoporotic Bone Fixation: Providing stable anchorage where conventional screw threads may fail to maintain a "grip" in low-density bone.

• Bridge Plating: Using locking constructs to span comminuted fracture zones without disrupting the fracture hematoma.
