Synthes 207.050 4.0mm Cancellous Bone Screw Partially Threaded/50mm

Synthes 4.0mm Cancellous Bone Screw | Partially Threaded | 50mm Length | 207.050

The Synthes 207.050 is a precision-engineered internal fixation implant designed specifically for engagement in cancellous (spongy) bone. As a 4.0mm diameter screw with a 50mm length, it is a foundational component of the Synthes Small Fragment System. This screw features a partially threaded design, which is the mechanical requirement for creating a "lag effect" to achieve high-pressure interfragmentary compression in metaphyseal or epiphyseal bone.

Forged from implant-grade 316L Stainless Steel, the 207.050 is designed to provide high pull-out resistance in the porous matrix of the bone, where standard cortical screws often lack sufficient anchorage.

Key Specifications

Technical & Clinical Advantages

• Mechanical Lag Effect: The partial threading ensures that the threads engage only the far (distal) bone fragment. Because the proximal 2.4mm shaft is smooth, the screw head draws the near cortex toward the far cortex as the screw is tightened, creating a powerful "vice-like" compression across the fracture gap.

• Cancellous Thread Geometry: The deep, 1.75mm pitch threads are specifically designed to "grip" the porous matrix of cancellous bone. This geometry maximizes surface area contact to prevent hardware pull-out in low-density bone environments.

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

• System Compatibility: The 6.0mm head is designed to sit flush within the counter-sunk holes of the Synthes Small Fragment LCP (Locking Compression Plate) and DCP systems, or it can be used with a 7.0mm washer for stand-alone fixation to prevent the head from sinking into soft bone.

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

• Malleolar Fixation: Ideal for medial malleolar fractures requiring significant interfragmentary compression.

• Plate Fixation: Serving as a "lag screw" through a 3.5mm LCP or DCP plate to achieve compression across an oblique fracture line.

• Large Fragment Avulsions: Anchoring bone fragments where a 50mm reach is required for secure distal purchase.

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 integrity of the 316L steel.

Shipping & Handling

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

• Fast Dispatch: Ships within 1 business day.
