Synthes 401.520.96 2.4mm Ti Cortex Screw Self-Tapping 20mm Orthopedic Hardware

Synthes 2.4mm Titanium Cortex Screw | Self-Tapping | 20mm Length | 401.520.96

The Synthes 401.520.96 is a high-performance internal fixation implant engineered for secure anchorage in dense cortical bone. Manufactured from commercially pure Titanium (Ti), this screw offers the highest level of biocompatibility and is the material of choice for patients with metal sensitivities. At a 2.4mm diameter and 20mm length, it is a core component of the Synthes Modular Hand System, designed to provide stable fixation for the metacarpals and larger phalanges.

The self-tapping distal tip features precision-machined cutting flutes, allowing the screw to be advanced into a $1.7\text{mm}$ pilot hole without the need for a separate tapping step. This ensures a high-tolerance "interference fit" while reducing operative time and mechanical stress on delicate bone fragments.

Technical & Clinical Advantages

• Advanced Titanium Biocompatibility: Titanium promotes excellent soft-tissue tolerance and minimizes the risk of post-operative allergic reactions. Its non-ferromagnetic properties allow for high-fidelity post-operative imaging (MRI/CT) with significantly reduced metal artifact compared to stainless steel.

• Self-Tapping Efficiency: The integrated cutting flutes reduce insertion torque and eliminate the need for manual tapping. This provides the surgeon with superior tactile feedback during insertion, which is critical when fixing small, fragile bone segments.

• Optimized Thread Pitch: The $1.0\text{mm}$ pitch is specifically calibrated for the dense cortical bone of the hand and midface, providing high pull-out resistance and stable long-term fixation.

• Low-Profile Cruciform Head: The $4.5\text{mm}$ head is designed to sit flush within the counter-sunk holes of Synthes Modular Hand plates and 2.4mm straight plates, reducing the risk of palpable hardware or tendon irritation in subcutaneous areas.

• Bicortical Versatility: At 20mm, this screw is ideal for bicortical fixation of the metacarpal shafts or for anchoring reconstructive bone grafts where a deeper thread purchase is required.

Applications

• Hand & Wrist Surgery: Fixation of metacarpal fractures, carpal fusions, and corrective osteotomies of the hand.

• Craniomaxillofacial (CMF) Surgery: Stabilization of mandibular fractures, orbital rim repairs, and reconstructive bone grafting.

• Podiatric Surgery: Fixation of metatarsal fractures and small-bone osteotomies.

• Modular Plating: Fully compatible with Synthes 2.4mm modular micro-plating and LCP systems.

Condition & Quality Assurance

• Status: NEW — Open Package / Individually Packaged.

• Integrity: This implant is new and has never been used. While listed as "Open Package," it is typically sourced from unused hospital overstock. As a non-sterile implant, it must be inspected for thread integrity and processed through a validated sterilization cycle (typically steam autoclaving) in accordance with hospital protocols and Synthes IFU (Instructions for Use) prior to clinical use in 2026.

• Professional Standards: With over 25 years of experience in surgical hardware, Primis Medical ensures all titanium implants are stored in climate-controlled environments to preserve the mechanical and sterile integrity of the system.

Shipping & Handling

• Secure Logistics: Shipped in protective, padded packaging to ensure the precision-machined 2.4mm threads and cruciform recess remain pristine.

• Fast Dispatch: Ships within 1 business day.
