“…The obvious benefit of the magnetic growing rod system is that repeat operations to perform rod lengthening are avoided, which is one of the main drawbacks of growing rods [13]. This is particularly useful in patients with high risk of complications from general anaesthesia, such as respiratory tract infection [14]. Considering that the minimum follow-up of patients in our series was 23 months, it is likely that all patients would have required at least three to four further surgeries to lengthen rods if a traditional growing rod system had been used.…”

Purpose Magnetically controlled growing rod systems have been introduced over recent years as an alternative to traditional growing rods for management of early onset scoliosis. The purpose of this paper is to report our early experience of a magnetically controlled growing rod system (MAGEC, Ellipse). Methods Review of pre-operative, postoperative and follow-up Cobb angles and spinal growth in case series of eight patients with a minimum 23 months' follow-up (23-36 months). Results A total of six patients had dual rod constructs implanted and two patients received single-rod constructs. Four patients had MAGEC rods as a primary procedure. Four were revisions from other systems. Mean age at surgery in the primary group was 4.5 years (range 3.9-6.9). In patients who had MAGEC as a primary procedure, mean pre-operative Cobb angle was 74°(63-94), with postoperative Cobb angle of 42°(32-56) p B 0.001 (43 % correction). Mean Cobb angle at follow-up was 42°(35-50). Spinal growth rate was 6 mm/year. One sustained proximal screw pull out. A final patient sustained a rod fracture. Mean age at surgery in the revision group was 10.9 years (range 9-12.6). Mean pre-operative Cobb angle was 45°( 34-69). Postoperative Cobb angle was 42°(33-63) (2 % correction). Mean Cobb angle at follow-up was 44°( 28-67). Mean spinal growth rate was 12 mm/year. Two patients developed loss of distraction.Conclusion MAGEC growing rod system effectively controls early onset scoliosis when used as either a primary or revision procedure. Although implant-related complications are not uncommon, the avoidance of multiple surgeries following implantation is beneficial compared with traditional growing rod systems.

“…A total of 7 articles met the initial inclusion criteria and were fully reviewed 13,15,17,21-24.

“…Preliminary results indicated MCGR was safe and provided adequate distraction similar to TGR technique, and can be used as dual-rod (DR) or single-rod (SR) technique of rod construct 13,15,17,21-24. As this is a relatively new technique, figures were added to illustrate a case in which the magnetic rods were implanted ( Figures 1-4 ).…”

Objective:To study the safety and efficacy of an innovative device using distraction-based magnetically controlled growing rods (MCGR) for the treatment of pediatric scoliosis.Methods:This is an evidence-based systematic review of literature for the surgical management of patients with pediatric scoliosis using MCGR technique. Six clinical studies regarding the use of MCGR were included in this review, with a total of 68 patients, and mean age of 8.38 years. The dual-rod (DR) technique of rod construct with MCGR was used in 33.85% and the single-rod (SR) in 66.15% of the patients.Results:The mean preoperative main coronal curve for the DR was 65.9°, and for the SR was 69.6° (p>0.05). At the latest follow-up, it was 36.8° for DR and 43.0° for SR (p<0.05). The mean preoperative T1-S1 spinal length was 298.7 mm for the DR and 303.5 mm for the SR group (p<0.05). According to the latest follow-up, using the DR construct, the spinal length increased to 347 mm with 13.92% of total lengthening; and using the SR construct, the average lengthening was 339 mm, with 10.48% of total lengthening (p<0.05). Postoperative complications were similar, 25% in DR and 31.57% in the SR group (p>0.05).Conclusion:Level IV of medical evidence supports the use of MCGR as a safe and effective alternative for the treatment of severe pediatric scoliosis. Recommendation Grade C supports the role of MCGR with DR construct as an option to achieve a better correction of the scoliotic curve and to maximize the postoperative T1-S1 spinal length.
