Abstract

Magnetically controlled growing rods have been used to treat early onset scoliosis during the last decade. Since the publication in 2015 of the report published by AETSA on this subject and, given the exponential growth of published studies, this update is proposed. OBJECTIVE The objective of this report is to evaluate the effectiveness and safety results of magnetically controlled growing rods in the treatment of early onset scoliosis. METHODS AND MATERIALS A systematic review and meta-analysis was carried out according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyzes) criteria. The databases of MedLine, Embase and Science Citation Index, and health technology evaluation organizations were consulted through a structured search until December 2018. Data on distraction frequency, number of distractions, length of distraction, respiratory function, quality of life, Cobb angle, kyphosis, length of T1-T12 and T1-S1 before and after the intervention, and at the final follow-up were collected. Data were also extracted regarding complications and unplanned reinterventions. To analyse the main results we used a meta-analysis with a random effects elongation procedure decreases with a greater number of subsequent distractions. A percentage greater than 40 % of the patients presented complications or required unplanned reoperations, increasing the probability of occurrence over time.
