Synthes 280.65 DHS/DCS Lag Screw 12.7mm Thread/65mm

Synthes DHS/DCS Lag Screw | 12.7mm Thread | 65mm | 280.65

The Synthes 280.65 is a high-precision internal fixation component of the Dynamic Hip Screw (DHS) and Dynamic Compression Screw (DCS) systems. This 65mm lag screw is specifically engineered to provide massive anchorage within the femoral head or distal femur, facilitating the "sliding" mechanism that defines these osteosynthesis systems.

The 12.7mm thread diameter provides an expansive surface area for purchase in cancellous bone. This high-profile thread maximizes pull-out resistance, which is vital for stabilizing hip fractures in elderly patients or those with compromised bone mineral density. When coupled with a DHS side plate, this screw allows for controlled fracture impaction along the axis of the screw, promoting biological healing through 2026 surgical standards.

Technical & Clinical Advantages

• Dynamic Sliding Mechanism: The smooth shaft of the 280.65 is precision-ground to slide freely within the barrel of a DHS/DCS plate. This allows the bone fragments to impact postoperatively under physiological load, shifting stress from the implant to the bone to facilitate union.

• Short-Length Optimization: At 65mm, this screw is ideal for patients with smaller femoral head anatomy or narrow femoral necks. It is frequently paired with Short Barrel DHS plates to ensure a full range of sliding motion without "bottoming out."

• Cannulated for Guided Accuracy: The 3.2mm internal bore allows the screw to be inserted over a 2.5mm guide wire. This ensures the screw is centered perfectly within the femoral neck, minimizing the risk of "cut-out" through the superior cortex of the femoral head.

• High-Torque Cancellous Grip: The deep 12.7mm threads are optimized for the femoral head's trabecular structure. The wide pitch ensures a strong "bite" that resists the high shear and rotational forces present during early mobilization.

• 316L Stainless Steel Biocompatibility: Forged from vacuum-melted surgical steel, the 280.65 offers the high fatigue strength and corrosion resistance required to support weight-bearing loads throughout the recovery cycle.

Applications

• Intertrochanteric Hip Fractures: The primary fixation element for stable and unstable pertrochanteric fractures in smaller-stature patients.

• Basilar Neck Fractures: Providing rotational stability and axial compression across the femoral neck.

• Subtrochanteric Fractures: When used in conjunction with a long-barrel DHS plate for patients with specific anatomical dimensions.

• Distal Femur Fractures: Serving as the anchor for the DCS (Dynamic Compression Screw) system in supracondylar applications.

Condition & Quality Assurance

• Status: NEW — Factory Sealed.

• Integrity: The implant is securely housed within its original manufacturer's packaging. Both inner and outer seals are intact, ensuring full material integrity and suitability for surgical use.

• 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.

• Professional Standards: With over 25 years of experience in orthopedic logistics, Primis Medical ensures all Synthes hardware is handled and stored to maintain mechanical and chemical precision.

Shipping & Handling

• Secure Logistics: Shipped in reinforced packaging to ensure the 65mm shaft and 12.7mm threads remain pristine and within factory tolerances.

• Fast Dispatch: Ships within 1 business day.
