Background: Magnetic Expansion Control System is an effective method in the treatment of pediatric scoliosis as it provides a balance between the deformity correction and the spine and lung growth.

Aim: This study aims to systematically review the literature regarding the role of the Magnetic Expansion Control System in the management of pediatric scoliosis.

Materials and Methods: Our present systematic review was performed by pre¬ferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. Included studies were English human studies that included patients with pediatric scoliosis, diagnosed before 10 years of age and treated by a magnetic expansion control system with a minimum follow-up period of 2 years. Cadaveric studies, case reports, review articles, commentaries, and general discussion papers were excluded.

Results: Nine included articles contained 226 patients (89 males and 137 females). The mean age of patients at the time of surgery was 8.4±1.2 years with a mean follow-up period (36.2±9.8 months). The mean curve magnitude was 63.9° preoperatively, corrected to 35.5° postoperatively, and was maintained to 38.8° at final-follow up. The mean T1-T12 length increased from 178.3 mm preoperatively to 194.9 mm postoperatively and 214.7 mm at final follow-up. The mean T1-S1 length increased from 298 mm preoperatively to 321.5 mm postoperatively and 352.3 mm at final follow-up.

Conclusion: Magnetic Expansion Control System is an effective method in the treatment of pediatric scoliosis as it permits spinal growth and is associated with a fewer rate of complications and unplanned surgeries compared to traditional growing rods. It is also a cost-effective method for long-term follow-up.
