Clinical Application
Schanz-style bone screws are percutaneous fixation elements used to secure external fixator constructs to bone. They provide skeletal anchorage for fracture reduction, temporary stabilization in acute trauma, staged reconstruction, deformity correction, and limb-lengthening procedures. Typical applications include long-bone diaphyseal and metaphyseal fixation where rigid purchase in cortical bone is required; the screw serves as the primary interface between the bone and external rods or clamps to maintain alignment during healing.
Design & Configuration
The externally threaded shank is engineered to engage cortical bone and deliver axial and rotational stability within an external fixation frame. The flat (blunt) tip reduces the likelihood of inadvertent penetration beyond the far cortex and can limit soft-tissue irritation at the distal tip compared with trocar points. The head geometry is configured for clamp or rod engagement, enabling secure mechanical coupling to standard external fixation hardware. Straight, rigid geometry facilitates percutaneous insertion using common pin drivers or handpieces and allows predictable alignment when mounting into clamp systems.
