Schanz Bone Screw w/Trocar tip

Clinical Application

Schanz bone screws with a trocar tip are used to achieve rigid purchase in cortical bone for temporary or definitive external fixation, skeletal traction, and intraoperative provisional stabilization during fracture reduction and limb reconstruction. Their percutaneous insertion profile and robust threaded shaft make them suitable for trauma cases where quick, reliable fixation to the diaphyseal cortex is required. These screws are commonly used with external fixator clamps and frames to create stable constructs for alignment, length maintenance, and soft-tissue management.

Design & Configuration

The trocar-style point provides a sharp, conical penetration geometry that facilitates initial cortical entry and controlled advancement through soft tissue. The screw’s threaded shaft is designed to engage cortical bone and resist pullout forces when used in external fixation constructs. A prominent head/interface allows secure engagement by manual insertion wrenches or power chucks and provides reliable connection to external fixator clamps. This combination of a pointed trocar tip and threaded shank reduces insertion resistance and helps achieve solid fixation with minimal soft-tissue stripping when placed percutaneously under fluoroscopic guidance.

Instrument Specifications

• Instrument type: Schanz-style bone screw for external fixation
• Tip: Trocar tip (sharp, pointed) for cortical penetration
• Configuration: Solid, threaded pin with head for insertion tool engagement or clamp attachment
• Typical use: External fixation, traction, temporary skeletal stabilization, percutaneous pinning
• Reusable: Yes (designed for repeated sterilization)

Material & Construction

Constructed from surgical-grade stainless steel to withstand mechanical loading and repeated sterilization cycles common in orthopedic instrumentation. The solid-pin construction provides torsional strength and resistance to bending during insertion and use. Reusable design supports reprocessing according to facility protocols for cleaning and sterilization.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.

Brand Comparison

Comparable in form and function to equivalent instruments offered by major US medical suppliers.
