摘要

Purpose

Early-onset scoliosis (EOS) is a challenging condition for spinal surgeons. Growing rods represent the standard treatment for patients requiring surgery, and magnetically controlled growing rods (MCGR) are increasingly adopted. Many patients ultimately transition to posterior spinal fusion (PSF), although the necessity of definitive fusion remains debated. This systematic review and single-arm meta-analysis aimed to evaluate radiographic and surgical outcomes of PSF following MCGR treatment.

Methods

A systematic literature search was conducted in PubMed, Google Scholar, Medline, Scopus, Embase, and the Cochrane Library up to April 2025, following PRISMA guidelines. Eligible studies were identified using a PIO (Population, Intervention, Outcome) framework. Extracted data included demographic, radiographic, and surgical outcomes, including complications. A single-arm meta-analysis compared pre- and post-PSF radiographic parameters (main curve magnitude, thoracic kyphosis (TK), T1–T12 and T1–S1 lengths). Risk of bias was assessed using the MINORS tool.

Results

Eight retrospective studies were included (370 patients), of which six were eligible for quantitative synthesis. The meta-analysis demonstrated significant improvements in all radiographic parameters (main curve magnitude, TK, T1–T12 and T1–S1 lengths, p < 0.05). The pooled overall postoperative complication rate after PSF was 17.2%.

Conclusions

PSF appears to be a viable treatment option following MCGR, providing significant deformity correction with a relatively acceptable complication rate. Nevertheless, the current evidence is limited by small, retrospective cohorts. Larger, prospective studies with standardized reporting of surgical variables and clinical outcomes are needed to better define the role of final fusion and to optimize treatment protocols.
