Synthes 212.112 3.5mm Locking Screw Self Tapping w/ Stardrive Recess 32mm

Synthes 3.5mm Locking Screw | Self-Tapping | StarDrive™ Recess | 32mm Length | 212.112

The Synthes 212.112 is a high-performance internal fixation implant 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 "Combi-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 32mm, this screw is designed for bicortical fixation in medium-sized long bones, such as the humerus, radius, ulna, or fibula, where stable anchorage and maximum pull-out resistance are required.

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 a common failure point in traditional non-locking systems.

• 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.

• Preservation of Blood Supply: Because the screw locks into the plate, it does not rely on pressing the plate against the bone to achieve stability. This "internal fixator" effect preserves the periosteal blood supply, facilitating faster biological healing.

• 316L Stainless Steel Integrity: Forged from cold-worked surgical steel, the 212.112 offers the high fatigue resistance necessary to withstand the cyclic loads of functional rehabilitation.

Applications

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

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

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

• Corrective Osteotomies: Securely maintaining bone alignment following reconstructive realignment procedures.
