Synthes 401.522.96 2.4mm Ti cortex screw self-tapping 22mm orthopedic hardware

Synthes 2.4mm Titanium Cortex Screw | Self-Tapping | 22mm | 401.522.96

The Synthes 401.522.96 is a high-precision internal fixation implant engineered for stable anchorage in dense cortical bone. As a 2.4mm diameter screw with a 22mm length, it is a foundational component of the Synthes 2.4mm Modular Hand and Mandible Systems. This screw is specifically designed for procedures where 2.0mm hardware may lack sufficient shear strength, but 2.7mm hardware is anatomically too large.

Constructed from implant-grade Titanium, the 401.522.96 offers superior biocompatibility and is non-magnetic, ensuring high-fidelity post-operative MRI and CT imaging with minimal metal artifact. The self-tapping distal tip allows for efficient insertion into a 1.8mm pilot hole, eliminating the need for a separate tapping step and providing the surgeon with excellent tactile feedback.

Technical & Clinical Advantages

• Titanium Biocompatibility: Commercially pure titanium promotes excellent osseointegration and minimizes soft-tissue irritation. Its lightweight properties are critical in hand and maxillofacial surgery, where excess hardware mass can interfere with functional recovery.

• Self-Tapping Efficiency: The precision-machined cutting flutes at the screw tip allow for direct insertion following a pilot drill. This reduces operative time and ensures a precise, high-friction interface between the screw threads and the bone.

• Optimized Core Strength: With a 1.7mm core diameter, this screw provides the high fatigue strength necessary to withstand the rotational and bending forces encountered in the metacarpals and mandible.

• Low-Profile Head: The 4.5mm head is designed to sit flush within Synthes 2.4mm plates. This profile is essential for preventing hardware palpability in areas with minimal soft-tissue coverage.

• High-Torque Cruciform Drive: The cruciform recess provides a secure interface between the screwdriver and the screw head, reducing the risk of "cam-out" or head stripping during insertion into dense bone.

Applications

• Hand & Wrist Surgery: Fixation of metacarpal shaft fractures and carpal fusions.

• Craniomaxillofacial (CMF): Stabilization of mandibular fractures and reconstructive bone grafting.

• Pediatric Orthopedics: Precise fixation in pediatric small bone fractures where larger hardware may be contraindicated.

• Forefoot Surgery: Stabilization of metatarsal osteotomies and midfoot fusions.

Condition & Quality Assurance

• Status: NEW — Factory Sealed & Sterile.

• Integrity: This implant is securely packaged within its original manufacturer's sterile peel-pouch. The packaging is intact, ensuring the product's sterility, material integrity, and full lot traceability for clinical implantation in 2026.
