Synthes 204.016 3.5mm Cortex Screw 16mm Orthopedic Surgical Instrument

Synthes 3.5mm Cortex Screw | Fully Threaded | 16mm Length | 204.016

The Synthes 204.016 is a foundational internal fixation implant designed for secure anchorage in dense cortical bone. As a 3.5mm diameter screw with a 16mm length, it is a core component of the Synthes Small Fragment System. This screw is engineered to provide maximum stability in diaphyseal bone, making it a primary choice for treating fractures of the forearm, fibula, and small fragments of the humerus and tibia.

Forged from implant-grade 316L Stainless Steel, the 204.016 features a fine thread pitch specifically calibrated to "bite" into the hard outer shell of the bone, providing superior pull-out resistance and compression when used in conjunction with orthopedic plating systems.

Key Specifications

• Manufacturer: Synthes (DePuy Synthes)

• Model / REF: 204.016

• Material: 316L Stainless Steel (Surgical Grade)

• Screw Diameter: 3.5 mm

• Screw Length: 16 mm

• Core Diameter: 2.4 mm

• Head Type: 2.5 mm Hexagonal Socket

• Quantity: Individually Packaged, Sterile

Technical & Clinical Advantages

• Optimized Cortical Pitch: Unlike cancellous screws, the 3.5mm cortex screw has a shallower, more frequent thread pattern designed to maximize surface area contact within the high-density cortical mineral matrix.

• High-Torque Hex Drive: The 2.5mm hexagonal recess is designed 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 engineered 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: At 16mm, this screw is frequently utilized for bicortical fixation in smaller long bones (like the 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 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 3.5mm small fragment plating systems.

• Malleolar Fixation: Stabilization of lateral malleolus fractures where 16mm of depth provides sufficient bicortical purchase.

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

Condition & Quality Assurance
