Abstract

This study aimed to identify the incidence of and potential risk factors for unplanned reoperations following traditional dual growing rods (TDGRs) combined with apical control techniques (ACTs; TDGRs+ACTs).
A retrospective study of patients with early-onset scoliosis treated with TDGRs+ACTs from June 2006 to November 2022 was conducted. The patients were grouped based on the occurrence of unplanned reoperations. Demographic characteristics, surgery-related data, radiographic parameters, complications, unplanned reoperations, and clinical outcomes were collected. Univariate and multivariate analyses were conducted to identify potential risk factors for unplanned reoperation following TDGR+ACT treatment. Receiver operating characteristic (ROC) curve analysis was used to identify the cutoff values.
A total of 60 patients were enrolled. The mean age at initial surgery was 7.2 years, with a mean follow-up duration of 6.5 years. Eleven patients (18.3%) underwent 14 unplanned reoperations by the final follow-up. Logistic regression analysis revealed that the 1-year progression rate of global kyphosis (GK; OR 1.211, p = 0.018) was a significant independent risk factor for unplanned reoperation. ROC analysis revealed that the 1-year progression rate of GK had good discriminatory ability (area under the curve 0.855, 95% CI 0.743-0.966), and the cutoff value was 12.5°/year. At the last follow-up, the mean emotion score in the reoperation group was significantly lower than that in the nonreoperation group (63.18 ± 20.16 vs 76.54 ± 18.90, p = 0.042).
The unplanned reoperation rate of TDGR+ACT treatment was 18.3%. The 1-year progression rate of GK was an independent risk factor for unplanned reoperation after TDGR+ACT, with the incidence of unplanned reoperation significantly increasing when the 1-year progression rate exceeded 12.5°/year. Unplanned reoperations not only affect the physical health of patients but also impose a heavy burden on their mental health.
