NICE has been notified about this procedure and it is part of its work programme. The Interventional Procedures Advisory Committee (IPAC) will consider this procedure and NICE will issue an interventional procedures consultation document about its safety and efficacy for 4 weeks’ public consultation. IPAC will then review the consultation document in the light of comments received and produce a final interventional procedures document, which will be considered by NICE before guidance is issued to the NHS in England, Wales, Scotland and Northern Ireland.

Description Minimally invasive deformity correction surgery is a non-fusion spinal surgery intended to treat idiopathic scoliosis (abnormal curvature of the spine that occurs without a known cause) in selected adolescents (from ages 8 to 18) whose bones have not fully matured. It is mainly used for correction of flexible single curves (thoracic major curve or thoracolumbar major curve) measuring up to 60 degrees. The procedure is done under general anaesthesia using a posterior unilateral approach. The concave side of the spinal curve is exposed through an incision around the apex of the curve. 3 pedicle screws are inserted into the vertebral bodies through the pedicle above and below the apex of the spinal curvature to serve as anchor points. A self-adjusting rod with an extender and 2 polyaxial joints (that allow a degree of spinal motion) is then fixed to the pedicle screws on the spine. Distraction during surgery is applied with a manual instrument to expand the rod and achieve curve/deformity correction (straighten the spine). 2-3 weeks after surgery, patients are advised to exercise daily so the self-adjusting rod allows additional elongation and achieves further correction to straighten the spine while the person continues to grow. It preserves spinal motion and minimises length of hospital stay and recovery time.
