Article Synopsis
- This study evaluates the effectiveness of magnetically controlled implant systems for treating severe spinal deformities in children, focusing on distraction length, complication rates, and their risk factors.
- Researchers followed 40 patients over an average of 34 months, measuring actual versus expected lengthening of the implants during bi-monthly procedures.
- Findings showed a 94.4% success rate in achieving expected distraction length, a low complication rate of 4.6% mainly linked to higher BMI, and a strong connection between distraction length and spinal growth, demonstrating the efficiency of this therapy.
Background: Children with severe spinal deformity frequently are managed with growth-friendly implants. After initial surgery, externally controlled magnetic rods allow spinal deformity correction during growth without further surgical intervention. The ability to lengthen the spine without additional surgical procedures is especially beneficial in high-risk children, such as those with spinal muscular atrophy (SMA).

However, spinal manipulation may lead to ossifications, stiffness, and autofusion as previously described. To avoid these problems, a surgical technique combining bilateral externally controlled magnetic device implantation with a rib cradle and pelvic hook fixation was introduced by us in 2011.
