Cannulated Screw System

Product Overview

The Acumed Cannulated Screw System is intended for fixation of fractures, fusions, and osteotomies of large and small bones appropriate for the size of the device. All screws are cannulated in order to be used over a guide wire, and each screw is either partially or fully threaded using a cancellous thread form.

Partially threaded screws may be used to lag one bone fragment to another, where the bone fragment is captured by the threads of the screw and pulled toward the near cortex fragment on the head side of the screw.

Fully threaded screws are intended to be used to stabilize fractures with little to no compression across the fracture.

The cannulated screws and instruments also allow for minimally invasive percutaneous insertion. The Cannulated Screw System is commonly used in the hip, pelvis, knee, ankle, and foot.
