Background. The management of early-onset scoliosis (EOS) remains a serious challenge in pediatric orthopedics. The growth-guidance system (GGS) is a surgical option that allows continuous growth along a rod, averting the need for repeated operative lengthening.
Objectives. The objective of this study was to evaluate the outcomes of the GGS in the treatment of EOS.
Material and Methods. A prospective study, including 81 patients from 4 departments treated with this method from 2013 to 2015, was conducted with a minimum follow-up period of 24 months. The follow-up data of 57 patients was available, thus the drop-out rate was 29.63%. There were 44 girls with a mean age of 10.03 years and 13 boys with a mean age of 8.04 years.
Results. The mean preoperative Cobb angle was 65.3° (range 36°–139°) was corrected to 23.7° (2°–94°), and at the end of the 2-year follow-up increased to 30.7° (8°–93°). The predominant proximal level of instrumentation was T5 and the distal was L1. The combined length of T1–T12 and T12–S1 increased on average by 33.19 mm in 24 months. The overall rate of serious complications was 43.86%. The most prevalent device-related complications were: the dislodgement of top screws because of the short length of the rod (14 cases), the implant failure (11 cases) and loss of correction (9 cases).
Conclusion. The results show that the GGS used in this study allows for a good and stable correction while preserving the ability of the spine to grow in at least a 2-year follow-up. The complication rate is acceptable and comparable with other growth-friendly techniques. To date, this is the largest successful study on the use of titanium-made GGSs.
