Abstract Study design Multicenter retrospective cohort study. Objectives To compare pre-operative and post-operative EOSQ-24 scores in magnetically controlled growing rods (MCGR) and traditional growing rod (TGR) patients. Summary of background data Since the introduction of MCGR, early-onset scoliosis patients have been afforded a reduction in the number of surgeries compared to the TGR technique. However, little is known about (health-related quality of life) and burden of care outcomes between these surgical techniques. Methods This is a retrospective cohort study using a multicenter registry on patients with EOS undergoing MCGR or TGR between 2008 and 2017. The EOSQ-24 was administered at preoperative and postoperative 2-year assessments. The EOSQ24 scores were compared between MCGR and TGR as well as preoperatively and postoperatively within each procedure. Results 110 patients were analyzed in this study (TGR, N = 32; MCGR, N = 78). There were no significant differences in preoperative age, gender, etiology, main coronal curve or maximum kyphosis between TGR and MCGR groups. Patients with TGR had averaged 3.9 surgical lengthenings and MCGR had averaged 7.7 non-invasive lengthenings by the 2-year follow-up. When changes in preoperative to postoperative scores were compared, MCGR had more improvements in pain, emotion, child satisfaction and parent satisfaction than TGR although there were no statistical significance. When analyzed separately, MCGR cohort had improvement in scores for all four domains and four sub-domains; while, TGR cohort only had improvement in financial burden domain and pulmonary function sub-domain. Conclusion Although there was no statistical significance, the improvement in pain, emotion and satisfaction scores was larger in MCGR than TGR. Since these areas can be influenced more by mental well-being than other sub-domains, the results may prove our hypothesis that compared to TGR, MCGR with reduced number of surgeries have better psychosocial effects.
