Synthes Medullary Reamer Head | 12.5 mm | 352.125 The Synthes 352.125 is a high-performance surgical cutting instrument engineered for the precise expansion of the medullary canal. As a 12.5mm diameter reamer head, it is a critical component used during intramedullary (IM) nailing of long bones, such as the femur and tibia. This specific size is often used in the final stages of canal preparation to accommodate larger diameter nails or to ensure an optimal fit for stable internal fixation. Constructed from high-grade surgical stainless steel, the 352.125 features a specialized flute geometry designed to efficiently clear bone debris (marrow and cancellous bone) while minimizing intramedullary pressure and the risk of fat embolism. Key Specifications Manufacturer: Synthes (DePuy Synthes) Model / REF: 352.125 Product Type: Medullary Reamer Head Diameter: 12.5 mm Material: Surgical Stainless Steel Compatibility: Standard Synthes Flexible Reamer Shafts Sterility: Provided Non-Sterile (Reusable) Sterilization Method: Moist Heat / Steam Autoclave Quantity: 1 Each Technical & Clinical Advantages Optimized Cutting Geometry: The precision-ground flutes are engineered to provide a clean, symmetrical circumferential cut. This ensures the medullary canal is perfectly centered, which is vital for the straight insertion of the intramedullary nail. Efficient Debris Clearance: The deep-flute design facilitates the rapid evacuation of bone "mud" and chips. This reduces the friction-generated heat during high-speed reaming, protecting the endosteal blood supply and promoting faster biological healing. Intramedullary Pressure Management: Synthes reamer heads are designed with specific relief gaps to allow for the bypass of pressure during advancement. This is a critical safety feature to mitigate the risk of pulmonary complications during trauma surgery. High-Torque Interface: The internal coupling is designed for a secure, "snap-fit" onto flexible reamer shafts, ensuring zero slippage even when encountering dense cortical bone in the diaphysis. Durability & Longevity: Forged from hardened stainless steel, the 352.125 maintains its cutting edge through multiple sterilization cycles, providing consistent performance across a high volume of cases. Applications Femoral Nailing: Preparing the canal for antegrade or retrograde femoral nails. Tibial Nailing: Reaming the tibial shaft to accommodate standard or interlocking nails. Revision Arthroplasty: Clearing the medullary canal of old cement or fibrous tissue to prepare for long-stem prosthetics. Non-union Management: Reaming to stimulate the endosteum and create a healthy biological environment for bone union. Condition & Quality Assurance Status: NEW — Individually Packaged. Integrity: This instrument is unused and maintains its factory-sharp cutting edges. It has been inspected for concentricity and flute alignment. Sterilization Requirement: This is a NON-STERILE, REUSABLE instrument. It must be thoroughly cleaned and sterilized via validated steam autoclave protocols (Moist Heat) in accordance with facility guidelines 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 surgical power tool attachments are stored and handled to maintain their mechanical precision. Shipping & Handling Secure Logistics: Shipped in a protective, rigid container to ensure the 12.5mm cutting flutes remain pristine and free of nicks or burrs. Fast Dispatch: Ships within 1 business day.
