Synthes 294.56 5.0mm Schanz Screw Blunted Trocar Point 200mm

Synthes 5.0mm Schanz Screw | Blunted Trocar Point | 200mm Length | 294.56

The Synthes 294.56 is a robust percutaneous pin engineered for the construction of Large External Fixation frames. As a 5.0mm diameter Schanz screw with an extended 200mm length, it is a foundational component for stabilizing high-energy fractures in major long bones such as the femur and tibia.

The Blunted Trocar Point is a specialized safety feature; while the sharp-edged trocar geometry facilitates initial cortical engagement, the "blunted" aspect is designed to provide tactile feedback and reduce the risk of inadvertent penetration into neurovascular structures or adjacent soft tissues on the far side of the bone.

Technical & Clinical Advantages

• High-Capacity Stabilization: The 5.0mm diameter provides the high area moment of inertia required to resist the significant bending and shear forces encountered in lower-extremity trauma.

• Optimized 50mm Thread: The 50mm threaded section is specifically sized to ensure full bicortical purchase in large long bones (femur/tibia). By engaging both the near and far cortex, the screw maximizes the mechanical stiffness of the entire fixator frame.

• Blunted Trocar Safety: The tip geometry allows for efficient entry into a pre-drilled $3.5\text{mm}$ pilot hole while providing a "safety buffer." This is particularly advantageous in anatomical regions where major vessels or nerves lie in close proximity to the exit cortex.

• Biomechanical Durability: Forged from cold-worked 316L stainless steel, the 294.56 offers exceptional fatigue resistance, ensuring the frame remains stable throughout the weeks or months required for biological bone healing or transport.

• Smooth Shaft Transition: The 150mm non-threaded proximal shaft is precision-polished to minimize friction and irritation at the skin-entry site, reducing the potential for pin-tract infections.

Applications

• Damage Control Orthopedics: Rapid provisional stabilization of unstable femoral or tibial shaft fractures in polytrauma patients.

• Knee & Ankle Bridging: Providing a stable "spanning" construct across complex intra-articular fractures.

• Arthrodesis: Temporary or definitive stabilization for large-joint fusions (knee/ankle) where internal fixation is contraindicated.

• Pelvic Stabilization: Use in anterior pelvic external fixators for the emergency management of unstable pelvic ring disruptions.

Condition & Quality Assurance

• Status: NEW — Original Manufacturer's Packaging.

• Integrity: This instrument is new. As a non-sterile implant/instrument, it must be inspected for thread integrity and processed through a validated sterilization cycle (typically steam autoclaving) in accordance with hospital protocols and Synthes IFU (Instructions for Use).

• Professional Standards: With over 25 years of experience in surgical hardware, Primis Medical ensures all external fixation components are maintained in optimal conditions to guarantee clinical reliability.

Shipping & Handling

• Secure Logistics: Shipped in reinforced, impact-resistant packaging to protect the threaded tip and precision-ground trocar point.

• Fast Dispatch: Ships within 1 business day.
