Synthes 218.050 6.5mm Cancellous Bone Screw Fully Threaded/50mm

Synthes 6.5mm Cancellous Bone Screw | Fully Threaded | 50mm | 218.050

The Synthes 218.050 is a high-performance internal fixation implant engineered specifically for anchorage in low-density cancellous bone. As a 6.5mm diameter screw with a 50mm length and a fully threaded profile, it is a foundational component of the Synthes Large Fragment LCP (Locking Compression Plate) System.

The fully threaded design is intended for positional fixation and maximum surface area engagement. Unlike partially threaded lag screws, this screw is designed to engage the trabecular bone across its entire 50mm span, providing superior pull-out resistance and maintaining the precise anatomical relationship of bone fragments under physiological load.

Technical & Clinical Advantages

• Optimized for Cancellous Bone: The wide 2.75mm thread pitch is specifically designed to grip the porous, "sponge-like" trabecular bone found in the metaphyses. This deep-thread geometry provides a significantly higher pull-out strength compared to cortical screws in the same anatomical region.

• Balanced Mechanical Profile: With a 3.2mm core diameter, the screw maintains a high fatigue threshold and resistance to bending while allowing for deep thread vanes that maximize bone purchase.

• Large Hexagonal Interface: The 8mm head features a robust hexagonal socket that ensures high torque transfer from the driver to the screw. This prevents "cam-out" and stripping, allowing for confident final seating in dense or sclerotic bone.

• LCP System Integration: Designed to fit perfectly through the non-locking portion of LCP combi-holes or standard large fragment plates, offering surgeons the versatility to use it for neutralisation, buttressing, or positional support.

• Bio-Corrosion Resistance: Forged from vacuum-melted 316L stainless steel, the 218.050 is biologically inert and resistant to the harsh environment of the human body throughout the 2026 healing cycle.

Applications

• Tibial Plateau Fractures: Providing stable anchorage for metaphyseal fragments and supporting articular surfaces.

• Distal Femoral Fractures: Used in supracondylar applications to secure large cancellous fragments.

• Proximal Humerus Reconstruction: Stabilizing the humeral head in multi-part fracture patterns.

• Pelvic Fixation: Providing positional stability in the iliac wing or near the sacroiliac joint where dense cortex is limited.

• Bone Graft Fixation: Securing large blocks of cancellous autograft or allograft.

Condition & Quality Assurance

• Status: NEW — Original Manufacturer's Packaging.

• Integrity: The implant is securely housed within its original packaging, ensuring the precision-machined threads and hexagonal drive remain in factory-perfect condition.

• Sterilization Note: This device is provided as a NON-STERILE implant. It MUST be properly cleaned and sterilized via validated steam autoclave protocols in accordance with facility guidelines and Synthes’ Instructions for Use (IFU) prior to clinical implantation.
