Synthes 5.0mm Self-Drilling Schanz Screw | 60mm Thread | 150mm Length | 294.784

The Synthes 294.784 is a high-performance external fixation pin engineered for rapid and secure anchorage in long bones. As a 5.0mm diameter Schanz screw with a 150mm overall length, it is a foundational component of the Synthes Large External Fixator system. This screw is specifically designed for the stabilization of fractures in the femur, tibia, and humerus.

The "Self-Drilling" designation is a critical mechanical feature. The distal tip is engineered with a high-efficiency cutting flute that eliminates the need for pre-drilling a pilot hole in most clinical applications. This reduces operative time, minimizes the risk of thermal necrosis by reducing friction, and ensures a precise, high-torque interface between the screw and the bone.

Technical & Clinical Advantages

• Self-Drilling Efficiency: The integrated drill tip allows for "one-step" insertion. This streamlines the surgical workflow in emergency trauma settings (e.g., "damage control" orthopedics) where rapid stabilization is vital to patient outcomes.

• Radial Prestress Technology: The screw geometry is designed to create a slight radial compression upon insertion. This "prestress" enhances the pin-to-bone interface, significantly reducing the risk of pin loosening and subsequent pin-track infection.

• 60mm Threaded Zone: The extensive 60mm thread length ensures that both the near and far cortices are fully engaged, providing a stable "bicortical" construct that can withstand the significant bending and rotational forces encountered in the lower extremities.

• High-Torque Drive: The proximal end is designed for a secure interface with manual or power drivers, ensuring efficient energy transfer even when penetrating dense femoral cortical bone.

• Biocompatible Strength: Forged from cold-worked 316L stainless steel, the 294.784 offers the high fatigue resistance necessary for long-term external fixation (weeks to months) without the risk of hardware failure.

Applications

• Damage Control Orthopedics: Rapid temporary stabilization of high-energy femoral or tibial fractures in polytrauma patients.

• Definitive External Fixation: Long-term stabilization of open fractures (Gustilo-Anderson Grade II/III) where internal fixation is contraindicated due to infection risk.

• Pelvic Stabilization: Anchorage into the iliac crest or supra-acetabular region for anterior pelvic frames.

• Pilon Fractures: Providing a stable proximal anchor for spanning ankle frames.

Condition & Quality Assurance
