Cannulated Cancellous Screw

The Cannulated Cancellous Screw 4.0 mm × 16 mm – Partially Threaded is an orthopedic fixation implant designed for fixation and compression of cancellous (spongy) bone during appropriate orthopedic surgical procedures. Its cannulated design incorporates a central channel that permits insertion over a compatible guidewire, helping the surgeon achieve controlled and accurate screw positioning. The partially threaded configuration can provide interfragmentary compression when appropriately applied as a lag screw, while the coarse cancellous thread is designed for fixation in lower-density cancellous bone. A 4.0 mm × 16 mm partially threaded cannulated cancellous screw is a recognized orthopedic implant size; device records and orthopedic implant catalogs specifically document this configuration. Key Features 4.0 mm screw diameter 16 mm screw length Partially threaded design Cannulated central channel for guidewire-assisted insertion Designed for cancellous/spongy bone fixation Partial threading facilitates compression across appropriately prepared fracture sites Provides controlled orthopedic fixation Suitable for selected small-bone and metaphyseal fixation procedures Available implant materials commonly include stainless steel or titanium, depending on manufacturer Designed for professional orthopedic surgical use
