Synthes 204.022 Cortex Screw 3.5mm x 22mm 1/EA

Synthes 3.5mm Cortex Screw | Fully Threaded | 22mm Length | 204.022

The Synthes 204.022 is a foundational internal fixation implant designed for secure anchorage in dense cortical bone. As a 3.5mm diameter screw with a 22mm 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 204.022 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: 204.022

• Material: 316L Stainless Steel (Surgical Grade)

• Screw Length: 22 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 22mm, this screw is frequently utilized for bicortical fixation in mid-sized 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 22mm 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
