Brace treatment can serve as a time-buying tactic for patients with congenital scoliosis

Abstract

Background: Infantile patients with congenital scoliosis (CS) can be confronted with increasing risk of mortality and morbidity. To date, the effectiveness of conservative treatment in CS has not been sufficiently investigated. We aimed to evaluate the bracing outcome in patients with CS and to investigate whether wearing brace can effectively delay the surgical procedures. Methods: A total of 39 braced CS patients including 25 boys and 14 girls were reviewed for the eligibility to be included in this study. Radiographic parameters including curve magnitude and T1 to T12 height were evaluated for each patient at the initiation of the treatment and at the final follow-up (FU), respectively. Duration of the follow-up and requirement of surgical interventions were also recorded. The student t test was used to compare the radiographic parameters between the initial visit and the last FU. Results: The mean initial age at bracing was 4.1 ± 2.3 years, and 7.5 ± 1.8 brace modifications were performed during a mean FU period of 42.1 ± 26.5 months. The mean curve magnitude before bracing was 44.1 ± 12.2°, which was corrected to 41.3 ± 13.5° at the final visit (p = 0.33). T1-T12 height increased from 13.4 ± 2.5 to 17.1 ± 2.8 cm during the treatment (P < 0.001). Nine patients underwent surgical intervention due to the curve progression more than 5°, with the time of surgery delayed for 32.1 ± 18.2 months. Conclusions: Brace treatment is an effective time-buying modality for CS patients, which may help maintain the body growth and delay the surgical intervention.
