Synthes 357.399 3.2mm Guide Wire 400mm Orthopedic Surgical Instrument

Synthes 3.2mm Guide Wire | 400mm Length | 357.399

The Synthes 357.399 is a high-tensile surgical instrument engineered to provide a precise anatomical path for cannulated instruments and implants. With a 3.2mm diameter and an extended 400mm length, this guide wire is a foundational component of the Synthes Proximal Femoral Nailing (PFN/PFNA) and Large Fragment Cannulated Screw systems.

Its primary function is to establish and maintain the correct longitudinal or angular trajectory during the fixation of proximal femur fractures. Once the wire is positioned under fluoroscopic guidance, it allows for the sequential passage of cannulated drills, reamers, and eventually the femoral nail or hip screws.

Key Specifications

• Manufacturer: Synthes (DePuy Synthes)

• Model / REF: 357.399

• Diameter: 3.2 mm

• Length: 400 mm

• Material: 316L Surgical Stainless Steel

• Tip Configuration: Typically Trocar or Threaded (System dependent)

• Compatibility: 6.5mm/7.3mm Cannulated Screws and Proximal Femoral Nails

• Quantity: 1 Each (Individually Packaged)

Technical & Clinical Advantages

• High Flexural Rigidity: Forged from cold-worked stainless steel, the 3.2mm diameter provides superior resistance to "skating" or bending when encountering dense cortical bone in the lateral femoral wall. This ensures the established trajectory remains true during instrument passage.

• Extended Surgical Reach: The 400mm length is critical for proximal femur procedures, providing sufficient length to span the femoral neck and head while leaving enough wire protruding laterally to facilitate the exchange of cannulated tools.

• Precision Surface Finish: The wire features a micro-polished surface to ensure smooth, low-friction gliding of cannulated drills and reamers, reducing the risk of "wire binding" or accidental advancement/withdrawal during instrument exchange.

• Biocompatible Durability: Manufactured from high-grade 316L stainless steel, the wire is designed to withstand the high rotational and axial forces of orthopedic surgery while remaining biologically inert.

• Intramedullary Navigation: Specifically calibrated for the internal diameter of Synthes PFN instrumentation, ensuring a secure "sliding fit" that maintains the centromedullary position of the reamer or nail.

Applications

• Proximal Femur Fractures: Guidance for the insertion of cephalomedullary nails (PFNA/InterTAN) in trochanteric and subtrochanteric fractures.

• Hip Fixation: Trajectory establishment for 6.5mm or 7.3mm cannulated screws in femoral neck fractures.

• Intramedullary Nailing: Leading wire for flexible reamers in long-bone diaphyseal stabilization.

• Corrective Osteotomies: Marking and maintaining the plane of correction during proximal femoral osteotomies.

Condition & Quality Assurance

• Status: NEW — Factory Sealed.

• Integrity: This instrument is unused and maintains its factory-specified straightness and tip sharpness. It is individually packaged to prevent surface nicks or contamination.

• Sterilization Note: This item is typically provided as a NON-STERILE instrument. It MUST be properly cleaned and sterilized (standard steam autoclave) in accordance with validated hospital protocols and Synthes’ Instructions for Use (IFU) prior to clinical application in 2026.

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

Shipping & Handling

• Secure Logistics: Shipped in a rigid, protective tube to ensure the 400mm length remains perfectly straight and the tips remain pristine during transit.

• Fast Dispatch: Ships within 1 business day.
