Synthes 204.040 3.5MM Cortex Screw 40MM

Synthes 3.5mm Cortex Screw | Fully Threaded | 40mm Length | 204.040

The Synthes 204.040 is a foundational internal fixation implant designed for secure anchorage in dense cortical bone. As a 3.5mm diameter screw with a 40mm length, it is a core component of the Synthes Small Fragment System. This screw is engineered to provide maximum structural stability in diaphyseal bone, making it a primary choice for treating fractures of the forearm (radius/ulna), fibula, and larger fragments of the humerus or tibia.

Forged from implant-grade 316L Stainless Steel, the 204.040 features a standard cortical thread pitch specifically calibrated to "bite" into the hard outer shell of the bone. This provides superior pull-out resistance when used for interfragmentary compression or in conjunction with orthopedic plating systems.

Technical & Clinical Advantages

• Optimized Cortical Pitch: The 1.25 mm thread pattern is designed to maximize surface area contact within the high-density cortical mineral matrix, ensuring a high-tolerance "interference fit."

• High-Torque Hex Drive: The 2.5 mm hexagonal recess is engineered to transmit the significant torque required to seat the screw into dense bone without the risk of "cam-out" or stripping the screw head.

• Low-Profile Spherical Head: The head geometry is precisely calibrated to sit flush within the counter-sunk holes of Synthes DCP (Dynamic Compression Plates), LC-DCP (Limited Contact), and LCP (Locking Compression Plates) systems.

• Bicortical Stability (40mm): At 40 mm, this screw is ideal for bicortical fixation in the distal humerus, radius, or fibula, where the screw engages both the near and far cortex for maximum mechanical stability.

• 316L Stainless Steel Biocompatibility: Cold-worked for high fatigue strength, the material is biologically inert and designed to withstand the cyclic loads encountered during the early stages of functional rehabilitation.

Applications

• Trauma Surgery: Fixation of diaphyseal fractures in the radius, ulna, and fibula.

• Plate Fixation: Serving as a "neutralization" or "compression" screw when used through 3.5 mm small fragment plating systems.

• Malleolar Fixation: Stabilization of lateral malleolus fractures where 40 mm of depth provides sufficient bicortical purchase.

• Pelvic Reconstruction: Use in small-fragment pelvic sets for the stabilization of specific acetabular or pelvic ring fractures.

Condition & Quality Assurance
