In 2017 NICE is due to commence the review of this guidance, to register as a stakeholder please contact us at

NICE has developed medical technology guidance on the MAGEC system for spinal lengthening in children with scoliosis.

NICE medical technologies guidance addresses specific technologies notified to NICE by manufacturers. The ‘case for adoption’ recommendations are based on the claimed advantages of introducing the specific technology compared with current management of the condition. This ‘case’ is reviewed against the evidence submitted and expert advice. If the case for adopting the technology is supported, then the technology has been found to offer advantages to patients and the NHS. The specific recommendations on individual technologies are not intended to limit use of other relevant technologies which may offer similar advantages.

NICE has said that the MAGEC system should be considered for children aged 2 and over with scoliosis, who need surgery to correct their curved spine. Hospital teams may want to use the MAGEC system because it avoids the need for repeated surgery to lengthen the rods. The MAGEC system can save money compared with conventional rods in the long term (after about 3 years).
