Synthes 206.016 4.0mm Cancellous Bone Screw Fully Threaded/16mm

Synthes 4.0mm Cancellous Bone Screw | Fully Threaded | 16mm Length | 206.016

The Synthes 206.016 is a precision-engineered internal fixation implant designed specifically for engagement in cancellous (spongy) bone. As a 4.0mm diameter screw with a 16mm length, it is a foundational component of the Synthes Small Fragment System. This screw features a fully threaded profile, providing maximum thread-to-bone contact across its entire length to ensure stable anchorage in low-density bone environments.

Forged from implant-grade 316L Stainless Steel, the 206.016 is designed to provide high pull-out resistance in the porous matrix of the metaphysis or epiphysis, where cortical screws may lack sufficient "grip."

Key Specifications

• Manufacturer: Synthes (DePuy Synthes)

• Model / REF: 206.016

• Material: 316L Stainless Steel (Surgical Grade)

• Screw Diameter: 4.0 mm

• Thread Profile: Fully Threaded

• Screw Length: 16 mm

• Thread Pitch: 1.75 mm

• Core Diameter: 1.9 mm

• Head Type: 6.0 mm Head with Small Hexagonal Socket

• Quantity: Individually Packaged (Non-Sterile)

Technical & Clinical Advantages

• Optimized Cancellous Pitch: The 1.75 mm thread pitch is significantly deeper and wider than cortical designs. This geometry allows the threads to "grasp" the trabecular bone structure, maximizing surface area contact to prevent hardware loosening.

• Full-Length Anchorage: Because the screw is fully threaded, it distributes mechanical loads evenly across the entire 16mm interface. This is particularly advantageous in osteoporotic bone or for fixing small avulsion fragments where every millimeter of purchase is critical.

• High-Torque Hex Drive: The hexagonal recess is designed to transmit precise insertion torque, allowing the surgeon to feel the "seat" of the screw without the risk of stripping the head or damaging the bone matrix.

• Low-Profile Spherical Head: The 6.0 mm head sits flush within the counter-sunk holes of Synthes small fragment plates (e.g., 3.5mm LCP, DCP, or LC-DCP) or can be used with a 7.0mm washer when fixed directly to the bone to prevent subsidence.

• Biomechanical Integrity: Cold-worked for high fatigue strength, this 316L stainless steel implant is biologically inert and designed to withstand the cyclic loads of functional rehabilitation.

Applications

• Trauma Surgery: Stabilization of metaphyseal fractures in the distal radius, medial malleolus, or olecranon.

• Avulsion Fractures: Securely anchoring small bone-tendon fragments (e.g., radial styloid or ankle ligaments).

• Plate Fixation: Serving as a "buttress" or "neutralization" screw through 3.5mm small fragment plating systems in regions of predominantly cancellous bone.

• Pediatric Orthopedics: Fixation of epiphyseal injuries where a short, 16mm reach is required to avoid growth plate interference.

Condition & Quality Assurance

• Status: NEW — Original Manufacturer's Packaging.

• Integrity: This implant is new. As a non-sterile component, it must be inspected for thread integrity and processed through a validated sterilization cycle (typically steam autoclaving) in accordance with hospital protocols and Synthes IFU (Instructions for Use) prior to clinical use in 2026.

• Professional Standards: With over 25 years of experience in surgical hardware, Primis Medical ensures all small fragment implants are maintained in optimal conditions to preserve the mechanical and sterile integrity of the system.

Shipping & Handling

• Secure Logistics: Shipped in protective packaging to ensure the precision-machined 4.0 mm threads and hexagonal socket remain pristine.

• Fast Dispatch: Ships within 1 business day.
