Abstract

We read with great interest the study titled “Radiological Outcomes of Magnetically Controlled Growing Rods for the Treatment of Children with Various Etiologies of Early-Onset Scoliosis—A Multicenter Study” by Grabala and colleagues [...]

“…Furthermore, congruent T1-T12 and T1-S1 extension values were noted during MCGR insertion surgery, with T1-T12 and T1-S1 parameters escalating by 52% and 51% of the total length achieved since MCGR implantation through the elongation process, resulting in an increase in T1-T12 and T1-S1 by 48% and 49%, respectively [15]. In reference to the analysis by the authors of the commentary concerning the T1-T12 and T1-S1 values [2], and the Cobb angle of the primary curvature, it can be deduced from our findings that despite the adverse parameters and potential complications arising from MCGR treatment, the application of magnetic rods allows for the attainment of satisfactory radiological and clinical outcomes.…”

“…We are immensely gratified by the considerable interest our study has garnered [ 1 ], leading to a multitude of correspondences and official remarks [ 2 ]. The scrutiny of our work and the comprehensive analysis of the research findings will result in a juxtaposition with other studies [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ], thereby enriching the advancement of spinal surgery and enhancing the surgical methodologies employed in treating pediatric patients afflicted with early-onset spinal deformities.…”

“…We express gratitude for the attention paid to segregating patients treated with MCGR from those who have completed the treatment and proceeded to final correction with spondylodesis. It is worth noting that our research was carefully conducted, and the amassed research findings were intended for publication across a series of publications rather than a singular one; however, due to numerous inquiries such as this letter to the editor, the remaining data will be incorporated into the subsequent response [ 1 , 2 ].…”

“…As elucidated by the authors [ 2 ] of the aforementioned study, the calculation for growth in the T1–T12 and T1–S1 segments entailed subtracting the initial postoperative value from the latest postoperative value [ 1 ]. This methodology was consistently applied to ascertain the maintenance of curve correction.…”

“…At the recommendation of the authors of the commentary [ 2 ], we have opted to disclose the actual radiological findings of patients undergoing treatment with the MCGR system, commencing from the initiation of treatment to the elongation of the MCGR rods until the conclusion of this process, prior to the ultimate surgical procedure. Table 1 comprises the radiological statistics of patients managed with MCGR, encompassing the final assessments before the conversion of MCGR to PSF, with the exception of the outcomes after the final surgery and PSF.…”
