Synthes 212.816 2.4mm Locking Screw Self-Tapping w/ Stardrive Recess 16mm

Synthes 2.4mm Locking Screw | Self-Tapping | T8 Stardrive | 16mm | 212.816

The Synthes 212.816 is a high-performance internal fixation implant engineered for stable, angular-stable anchorage in small bone fragments. As a 2.4mm diameter screw with a 16mm length, it is a foundational component of the Synthes 2.4mm LCP (Locking Compression Plate) Distal Radius System.

The defining characteristic of this locking screw is its threaded head, which mechanically engages with the corresponding threaded holes of an LCP plate. This creates a "fixed-angle" construct, providing superior stability in osteoporotic bone or comminuted fractures where traditional screw purchase (friction-based) is insufficient. At 16mm, this screw is frequently utilized for the stabilization of intermediate fragments in the distal radius or metacarpals.

Technical & Clinical Advantages

• Angular Stability: The threaded head locks into the plate, ensuring the screw cannot toggle or back out. This effectively turns the plate and screw into a single rigid construct, preserving anatomical reduction even under physiological loads.

• T8 Stardrive Recess: The StarDrive interface offers significantly higher torque transmission compared to traditional hexagonal drives. This reduces the risk of "cam-out" or head stripping, which is critical during the high-torque final locking phase into the plate.

• Self-Tapping Efficiency: Precision-machined cutting flutes at the tip allow the screw to create its own thread path as it is advanced into a 1.8mm pilot hole. This minimizes operative time and ensures a precise fit within the cortical bone.

• Vascular Preservation: Because stability is achieved through the locking mechanism rather than plate-to-bone compression, the plate does not need to be seated tightly against the periosteum. This "limited contact" approach preserves the vital blood supply to the bone.

• 316L Stainless Steel Biocompatibility: Forged from cold-worked surgical steel, the 212.816 offers high fatigue strength and the corrosion resistance required for long-term internal fixation in 2026.

Applications

• Distal Radius Fractures: Primary fixation in volar or dorsal 2.4mm LCP plates.

• Hand & Wrist Surgery: Stabilization of metacarpal fractures or carpal fusions requiring angular stability.

• Forefoot Reconstruction: Use in 2.4mm locking plates for metatarsal osteotomies or midfoot fusions.

• Pediatric Trauma: Small bone fixation where stable constructs are required despite smaller anatomical dimensions.
