Synthes 400.824.96 1.5mm Ti Cortex Screw Self-Tapping 24mm

Synthes 1.5mm Titanium Cortex Screw | Self-Tapping | 24mm Length | 400.824.96

The Synthes 400.824.96 is a high-precision micro-fixation implant engineered for secure anchorage in dense cortical bone. Manufactured from commercially pure Titanium (Ti), this screw provides superior biocompatibility and is the material of choice for patients with metal sensitivities or those requiring high-fidelity post-operative imaging. At a 1.5mm diameter and an extended 24mm length, it is a specialized component of the Synthes Modular Hand and Micro-Fragment systems, designed for "cross-bone" stabilization where standard micro-screw lengths are insufficient.

The self-tapping distal tip features precision-machined cutting flutes, allowing the screw to carve its own thread path as it is advanced into a 1.1mm pilot hole. This eliminates the manual tapping step, which is critical when navigating a 24mm path through delicate, small bone fragments.

Technical & Clinical Advantages

• Advanced Titanium Biocompatibility: Titanium promotes excellent soft-tissue tolerance and osseointegration. Its non-ferromagnetic properties allow for high-fidelity post-operative MRI and CT scans with significantly reduced metal artifact compared to stainless steel.

• Extended Bicortical Reach: At 24mm, this screw is exceptionally long for a 1.5mm diameter. It is optimized for oblique "lag" trajectories or for spanning the full width of metacarpals or phalanges in complex reconstructive cases.

• Self-Tapping Efficiency: The integrated cutting flutes reduce insertion torque and eliminate the need for a separate tapping tool. This provides the surgeon with superior tactile feedback, which is essential when fixing fragile bone segments to prevent stripping.

• Low-Profile Cruciform Head: The head is designed to sit flush within Synthes 1.5mm Micro-Plating systems, reducing the risk of palpable hardware or tendon irritation in areas with minimal soft tissue cover.

• Ultra-Fine Thread Pitch: The 0.5mm pitch provides a high thread density, maximizing pull-out resistance even in the very thin cortical layers of the hand or midface.

Applications

• Hand & Micro-Surgery: Bicortical fixation of phalangeal and metacarpal fractures where a very low-profile, long-reach screw is required.

• Craniomaxillofacial (CMF) Surgery: Stabilization of midface fractures or reconstructive bone grafting requiring deep purchase.

• Neuro-Surgical Fixation: Anchoring small bone flaps or mesh where 1.5mm hardware is indicated.

• Small Bone Reconstructive Trauma: Providing stable anchorage in complex, comminuted micro-fractures of the extremities.

Condition & Quality Assurance

• Status: NEW — Factory Sealed & Sterile.
