Synthes 280.15 DHS/DCS Lag Screw 12.7mm Thread/115mm

Synthes DHS/DCS Lag Screw | 12.7mm Thread | 115mm | 280.15

The Synthes 280.15 is a cornerstone component of the Dynamic Hip Screw (DHS) and Dynamic Condylar Screw (DCS) systems. At 115mm in length, this lag screw is designed to provide massive purchase in the femoral head or the distal femoral condyles.

Its primary mechanical function is to interface with a DHS or DCS side plate. The screw provides a high-torque grip in the bone fragment, allowing it to "slide" within the plate's barrel. This creates controlled dynamic compression, utilizing the patient's physiological loading to impact the fracture and accelerate biological bone union.

Technical & Clinical Advantages

• Cancellous Thread Profile: The 12.7mm threads are deep-cut and wide-pitched, specifically designed to maximize "grip" in the cancellous (spongy) bone of the femoral head. This design is critical for preventing "cut-out," a common failure mode in osteoporotic geriatric hip fractures.

• Precision Cannulation: The screw features a hollow core, allowing for insertion over a 2.5mm guide pin. This enables the surgeon to verify the exact trajectory via fluoroscopy (X-ray) before the final implant is seated, ensuring the screw is perfectly centered within the femoral neck.

• Polished Gliding Shaft: The 8.0mm shaft is precision-polished to slide without friction inside the barrel of the side plate. This ensures that the "sliding" mechanism remains active post-operatively, allowing the fracture to settle and compress naturally during the 2026 healing cycle.

• Anti-Rotation "Two-Flat" Design: The lateral end of the screw features two machined flats. These engage with the internal geometry of the plate barrel to prevent the bone fragment from rotating around the screw, maintaining anatomical alignment and rotational stability.

• 316L Surgical Steel: Forged from vacuum-melted stainless steel, the 280.15 offers the high fatigue strength required for early-mobilization trauma protocols.

Applications

• Intertrochanteric Hip Fractures: The standard application for securing the femoral head to the femoral shaft using a 140° or 135° DHS plate.

• Subtrochanteric Fractures: Providing stable medial-to-lateral fixation in high-stress areas of the proximal femur.

• Distal Femur Fractures: Used with a DCS (Dynamic Condylar Screw) plate to stabilize supracondylar or intercondylar fractures of the knee.

• Basilar Neck Fractures: Offering superior stability compared to isolated cannulated screws for fractures at the base of the femoral neck.

Condition & Quality Assurance

• Status: NEW — Factory Sealed.

• Integrity: The implant is securely packaged in 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 hospital 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 stored in climate-controlled environments to preserve mechanical tolerances.

Shipping & Handling

• Secure Logistics: Shipped in reinforced packaging to protect the 12.7mm threads and ensure the 115mm shaft remains perfectly straight.

• Fast Dispatch: Ships within 1 business day.
