Synthes 206.020 4.0mm Cancellous Bone Screw Fully Threaded 20mm

Synthes 4.0mm Cancellous Bone Screw | Fully Threaded | 20mm Length | 206.020

The Synthes 206.020 is a precision-engineered internal fixation implant designed specifically for use in cancellous (spongy) bone. As a 4.0mm diameter screw with a fully threaded profile, it is optimized for applications where maximum thread-to-bone contact is required to maintain stable fixation in low-density bone. At 20mm in length, it is a versatile component of the Synthes Small Fragment System, frequently used in the epiphysis and metaphysis of long bones.

Forged from implant-grade 316L Stainless Steel, the screw features deep, widely spaced threads that provide superior pull-out resistance compared to cortical designs.

Technical & Clinical Advantages

• Optimized Cancellous Pitch: The deep thread profile is specifically designed to "grip" the porous matrix of cancellous bone. The fully threaded design ensures that the screw provides consistent anchorage along its entire 20mm length, distributing mechanical loads evenly.

• Superior Pull-out Resistance: By maximizing the thread-to-bone surface area, the 206.020 provides the high degree of stability necessary to prevent fragment displacement during the critical early stages of bone healing.

• High Torque Hex Drive: The 2.5 mm hexagonal recess allows for the transmission of high insertion torque without the risk of "cam-out" or stripping the screw head, ensuring secure final seating even in dense metaphyseal bone.

• Low-Profile Spherical Head: The head is designed to sit flush within the counter-sunk holes of Synthes small fragment plates (e.g., 3.5mm LCP or DCP systems) or directly against the bone surface with a 7.0mm washer to prevent hardware subsidence.

• 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 metaphyseal fractures in the distal radius, tibial plateau, or pilon fractures.

• Malleolar Fixation: Stabilization of medial malleolar fractures where the bone is primarily cancellous.

• Plate Fixation: Serving as a "neutralization" or "buttress" screw through 3.5mm LCP or DCP plating systems in regions of thin cancellous bone.

• Pediatric Orthopedics: Fixation of epiphyseal injuries where 20mm of depth provides secure purchase without crossing the growth plate.

Condition & Quality Assurance

• Status: NEW — Factory Sealed & Sterile.

• Integrity: This implant is securely packaged within its original manufacturer's sterile peel-pouch. The packaging is intact, ensuring the product's sterility, material integrity, and full lot traceability for clinical implantation in 2026.
