Plastic spinal surgery device outperforms traditional metal instrument


A single-use, plastic instrument for spinal surgery has proved its mettle in a comparative strength study performed by the Orthopaedic Trauma Institute at the University of California San Francisco (UCSF). The disposable lumbar device developed by Xenco Medical (San Diego, CA) showed "no visible fracture" at 40 mm of cantilever deflection, whereas "the aluminum instrument exhibited significant deformation," noted the UCSF report.

One component in the company's line of disposable cervical and lumbar spinal systems, the first-of-its-kind device is made of a reinforced composite polymer that withstood a continuously applied load of 25 mm/min. The material's strength and the fact that it eliminates any chance of infection because it is a single-use device are an illustration of the company's manifesto of "disruptive innovation for the purposes of creating a safer surgical environment."
