Request product
start requestCOSY® is a occiputal cervical-thoracic system (OCTS) for posterior surgical immobilisation, stabilisation and correction of malpositions of the human cervical spine and the cervicothoracic junction, including the occipitocervical junction if necessary. The implants are available in various lengths, diameters and sizes to enable adaptation to different patient anatomies.
The COSY® system comprises rods, hooks, screws, polyaxial screws, fixation screws, connecting pieces, occipital plates and occipital screws in various sizes that can be firmly connected to a rod in various configurations. The system includes transition rods (hybrid rods) from 3.5 mm to 5.5 or 6.0 mm in diameter and parallel rod-to-rod connectors. For stabilisation and fusion of the occipitocervical junction the system provides occipital plates with corresponding scews and rods in various sizes. The fixation of the occiput can be extended to the thoracolumbar area with the transition rods. These components are intended to allow connection of the COSY® Cervicothoracic Occipital Rod-Screw System to a thoracolumbosacral pedicle screw system (DIPLOMAT®).
