Before Surgery
Treatment options for paediatric patients suffering from idiopathic scoliosis are limited.
For patients with a progressive scoliosis, that have failed bracing or become intolerant to brace wear, the most common surgical option is spinal fusion.
Before Surgery
Spinal fusion has proven to be a successful treatment option for idiopathic scoliosis, however it is not without its drawbacks.
Reported clinical challenges of spinal fusion include 1-2:
Limited motion
Arrested growth
at the levels treated
Disc degeneration in
adulthood
After Tether Surgery
For patients that would otherwise be treated with spinal fusion, The Tether Vertebral Body Tethering System may now offer an alternative option.
The Tether replaces stiff metal rods with a flexible cord designed to offer greater post-operative mobility, continued spinal growth and secondary curve correction based on the Hueter-Volkmann Law3.
After Tether Surgery
As spinal mobility is inherent to The Tether’s design concept, it is intended to allow paediatric patients to continue or return to activities that might otherwise be difficult following spinal fusion.
Surgery is also typically performed via a minimally invasive thoracoscopic approach, associated with shorter operating times, hospital stays and quicker return to normal activities4-5.
How The
Tether works
The Tether is intended to treat skeletally immature patients with a main thoracic curve (Lenke Type 1) with a major Cobb angle of 30° to 65° whose osseous structure is dimensionally adequate to accommodate screw fixation*.
