Synthes 214.832 4.5mm Cortex Screw Self-Tapping 32mm Orthopedic Hardware

Synthes 4.5mm Cortex Screw | Self-Tapping | 32mm | 214.832

The Synthes 214.832 is a high-strength internal fixation implant engineered for stable anchorage in dense cortical bone. As a 4.5mm diameter screw with a 32mm length, it is a foundational component of the Synthes Large Fragment System. This screw is specifically designed for the stabilization of fractures in long bones such as the femur, tibia, and humerus, where substantial mechanical loads require robust hardware.

Constructed from 316L Surgical Stainless Steel, the 214.832 features a self-tapping distal tip with precision-machined cutting flutes. This design allows the screw to create its own thread path as it is advanced into a 3.2mm pilot hole, enhancing surgical efficiency and providing the surgeon with superior tactile feedback during final seating.

Technical & Clinical Advantages

• Self-Tapping Efficiency: The integrated cutting flutes eliminate the need for a separate tapping step in most cortical bone applications. This reduces operative time and ensures a precise, high-friction interface between the screw threads and the bone.

• High-Torque Hex Drive: The 3.5mm hexagonal socket allows for the application of significant insertion torque required to seat the screw into thick diaphyseal bone without the risk of "cam-out" or head stripping.

• Optimized Pitch for Cortical Bone: The 1.75mm thread pitch is specifically engineered to maximize surface area contact within the dense cortical shell, providing exceptional pull-out resistance and long-term stability.

• Universal System Compatibility: The 8.0mm spherical head is designed to sit flush within Synthes 4.5mm DCP (Dynamic Compression Plates), LC-DCP, and LCP (Locking Compression Plate) systems, facilitating both compression and neutralization constructs.

• Bicortical Fixation: The 32mm length is ideal for achieving "two-point" bicortical fixation in the adult humerus or tibia, which is the mechanical gold standard for preventing hardware migration under physiological load.

Applications

• Long Bone Fractures: Primary fixation for diaphyseal fractures of the femur, tibia, and humerus.

• Plate Fixation: Securing large fragment compression or neutralization plates to the bone surface.

• Osteotomies: Stabilizing bone-cut sites in reconstructive extremity surgery.

• Non-union Repair: Utilizing high-torque cortical purchase to achieve stability in revision cases where previous hardware has failed.

Condition & Quality Assurance

• Status: NEW — Individually Packaged.

• Integrity: This implant is unused and maintains its original material integrity.

• Packaging Note: This item is identified as Open Package. While the outer bulk manufacturer's box may have been removed, the screw has been visually inspected for thread and drive-socket integrity.

• Sterilization Requirement: This is a NON-STERILE implant. It must be properly cleaned and sterilized (typically via steam autoclave) in accordance with validated hospital protocols and Synthes’ Instructions for Use (IFU) prior to clinical implantation in 2026.

• Professional Standards: With over 25 years of experience in surgical hardware, Primis Medical ensures all Synthes implants are handled with the highest degree of quality control.

Shipping & Handling

• Secure Logistics: Shipped in protective packaging to ensure the precision-machined 32mm threads and hexagonal drive remain pristine.

• Fast Dispatch: Ships within 1 business day.
