Clinical and radiological results of final fusion in patients who underwent lengthening with magnetically controlled growing rods. About 66 patients with a mean follow-up of 5?years

摘要

Abstract Purpose The aim of this study was to evaluate the effects of definitive arthrodesis on frontal and sagittal spine balance in EOS patients treated with MCGR, as well as the complications associated with this procedure and the outcome at last follow-up.Methods This was a multicentre study in 10 French centres. All patients who underwent posterior spinal arthrodesis after completion of MCGR treatment, regardless of age, etiology of scoliosis between 2011 and 2022, were included.Results A total of 66 patients who had a final fusion after the lengthening programme were included in the study. The mean follow-up time was 5.5?±?1.7?years (range: 2.1–9). The mean follow-up time after arthrodesis was 24?±?18?months (range: 3–68) and the mean age at arthrodesis was 13.5?±?1.5?years (range: 9.5–17). The main and secondary curves were significantly (p?
