Spinal tether system for scoliosis gets FDA nodOctober 8, 2019
A spinal tether device to correct scoliosis has been approved by the USFDA, said Zimmer Biomet.
The device is intended to be used in children and adolescents to correct idiopathic scoliosis, that has not responded to conservative treatment options, such as external bracing.
Called Tether – Vertebral Body Tethering System, can be used to correct spinal curves that are approaching or have reached the range where surgical treatment is an option.
The system includes anchors and vertebral body screws that are placed into the same side of each vertebra in the curved section of the spine through an incision on the side of the chest. A flexible cord, called a tether, is connected to the screws. Tension is applied to the tether during surgery to compress one side of the spine and to partially correct the curve. Over time, the tether slows growth on the curved side of the spine and promotes growth on the opposite side. This provides additional correction of the curve as the patient continues to grow.
