Synthes 401.528.96 2.4MM TI Cortex Screw Self Tapping 28MM

Synthes 2.4mm Titanium Cortex Screw | Self-Tapping | 28mm Length | 401.528.96

The Synthes 401.528.96 is a high-precision internal fixation implant designed for small fragment stabilization. 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 long-term fixation where MRI compatibility is a priority. With a 2.4mm diameter and an extended 28mm length, it is a foundational component of the Synthes Modular Hand System.

The self-tapping distal tip features precision-engineered 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 enhances operative efficiency and ensures a high-tolerance interface with the cortical bone.

Technical & Clinical Advantages

• Titanium Biocompatibility: Titanium is highly resistant to corrosion and facilitates excellent soft-tissue tolerance. Its non-ferromagnetic properties allow for safe post-operative imaging via MRI.

• Extended Bicortical Engagement: At 28mm, this screw is designed for bicortical fixation in larger small-bone structures, such as the metacarpals, carpals, or distal radius, providing maximum pull-out resistance.

• Self-Tapping Efficiency: The distal cutting flutes reduce insertion torque and eliminate the need for manual tapping. This is particularly advantageous in dense cortical bone where maintaining fragment alignment is critical.

• StarDrive™ / Cruciform Compatibility: The 4.5mm head is designed for secure engagement with Synthes drivers, ensuring high torque transmission and reducing the risk of "cam-out" during final seating.

• Low-Profile Head Design: Engineered to sit flush within Synthes Modular Hand plating systems, minimizing palpable hardware and reducing the risk of tendon irritation in the hand and wrist.

Applications

• Hand and Wrist Surgery: Fixation of metacarpal and phalangeal fractures, as well as small-bone arthrodesis.

• Craniomaxillofacial (CMF) Surgery: Stabilization of mandibular or midface fractures where a 2.4mm profile is required.

• Trauma Surgery: Stabilization of small bone fragments and avulsion fractures.

• Plate Fixation: Compatible with 2.4mm system plates, including LCP and modular reconstructive modules.
