Product Overview

HOOK
OASYS - 48551049


Device Description

An implantable component of a bone-screw internal spinal fixation system that has a curved (hook-shaped) design intended to provide immobilization and stabilization of spinal segments in the treatment of various spinal instabilities or deformities, and also used as an adjunct to spinal fusion [e.g., for degenerative disc disease (DDD)]. This component is typically made of metal [e.g., titanium (Ti)] and placed/hooked around the lamina or pedicle of a vertebra, without penetration (i.e., not a screw), to provide a stable connection for the system’s rod; the rod is typically stabilized in the U-shaped hook head with a small lid or screw.

    Device Name: Posterior Cervical Screw System

    Device Class: 2

    Physical State: Metallic plates, longitudinal members (e.g., rods) and other device-specific accessories.

    Definition: Posterior cervical screw systems are intended for use in fusion procedures of the cervical spine and/or craniocervical junction and/or cervicothoracic junction for: 1) spinal fractures and dislocations; 2) deformities; 3) instabilities; 4) failed previous fusions; 5) tumors; 6) inflammatory disorders; 7) spinal degeneration, 8) facet degeneration with instability; and 9) reconstruction following decompression to treat radiculopathy and/or myelopathy. These systems are also intended to stabilize the spine in the absence of fusion for a limited time period in patients with tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.
