The Tether™ Vertebral Body Tethering System

Ahead Of The CurveTM

The Tether™ – Vertebral Body Tethering System is a non-fusion spinal device intended for treatment of idiopathic scoliosis. Anchors and vertebral body screws are placed laterally from a thoracoscopic or thoracotomy approach into the vertebral body on the convex side of a spinal deformity.

A SULENE® polyethylene terephthalate (PET) tensioning cord is secured to the vertebral body screws with set screws to connect the levels of the construct. The device provides a lateral tension band across the convex side of the spine that, on insertion and tensioning, partially corrects the curvature, and subsequently can arrest or correct the deformity through modulation of remaining spinal growth. In addition, the subject system includes instrumentation for insertion, manipulation, and removal of the implants.

System Features

The Tether™ - Vertebral Body Tethering System is different from the other surgical treatments for scoliosis — e.g. spinal fusion — because the spine is still able to bend and flex, rather than being fixed in place with the stiff metal rods needed for spinal fusion.

• There may be smaller incisions required (less scarring).
• Tether with Spine and Ribs Designed to allow for motion at the levels treated.
• There may be less muscle and soft tissue disruption.
