  Purpose

It is current practice for children who have surgery for early onset scoliosis (EOS) to be treated with insertion of extendable implants known as growth rod systems. This allows the growth potential of the child to be maximised during the period of growth. However, the child must undergo an average of 6 further surgeries to lengthen the rods every 6 months. Sometimes this may continue for several years. This requires repeated general anaesthesia and places the patient at risk of complications as well as on-going costs to the hospital with each admission and theatre episode.

Magec is a magnetic growth rod from Ellipse technologies (distributed by SurgiC). The rod is inserted in exactly the same way as the conventional growth rod systems. The base implants i.e screws and hooks remain the preferred choice of the user. The only change is that a different rod is used.

There are several advantages to this device. Firstly, after the initial insertion, further lengthenings, unlike current systems, do not need to be carried out in theatre under a general anaesthetic. In contrast, they can be done in an outpatients setting with a non-invasive technique. The rods are lengthened using an external magnetic device. The lengthenings are done in a controlled manner using an age related growth guide. Thirdly, the change from a theatre based intervention to an outpatient procedure will have cost-savings. The investigators also believe that there will be psychosocial benefits to the child and family by the avoiding the stress associated with repeated surgery at such a young age.

In terms of risk assessment the device does not place the child at any more risk than would be expected from inserting any of the existing systems. In the event of failure of the rods the worst outcome is a revision to conventional rods.

Criteria

Inclusion Criteria:

  1. Patient aged 2 - 10 years (male/female) with EOS and growth potential
  2. Patient who surgeon feels would benefit from the implantation of a growth rod
  3. Patient must be of appropriate size and age for use of the device

Exclusion Criteria:

  • The participant may not enter the study if ANY of the following apply:

    1. Conversion patients with prior construct problems
    2. Previous diagnosis of post-operative spinal infection or wound complication
