Three-Staged correction of severe congenital scoliosis with type I split cord malformation: a retrospective study without vertebral osteotomy
摘要
To explore the safety and efficacy of three staged treatment for extremely severe congenital scoliosis (CS) with type Ⅰ split cord malformation (SCM).
MethodsThe clinical data of 26 patients with extremely severe CS and type Ⅰ SCM were retrospectively analyzed. The height (cm), weight (kg), coronal and sagittal Cobb Angles (°), coronal and sagittal balances (cm), coronal and sagittal correction rates (%) were recorded at admission(A), before(B) and after(C) thoracoplasty + spinal instrumentation.
ResultsAll the patients were followed up for three years. The heights at time A, B and C were 136.58 ± 9.60 cm, 146.27 ± 9.90 cm and 151.27 ± 9.51 cm respectively. The weights at time A, B and C were 40.02 ± 8.38 kg, 43.98 ± 7.18 kg and 43.33 ± 6.40 kg respectively. The coronal Cobb Angles at time A, B and C were 139.93 ± 21.58°, 84.82 ± 19.48°and 55.03 ± 18.35°respectively. The sagittal Cobb Angles at time A, B and C were 90.18 ± 23.56°, 64.05 ± 10.88°and 42.33 ± 8.88°respectively. The coronal balances at time A, B and C were 48.02 ± 33.11 cm, 22.75 ± 19.87 cm and 14.07 ± 13.71 cm respectively. The sagittal balances at time A, B and C were 37.41 ± 26.99 cm, 22.16 ± 22.03 cm and 12.61 ± 18.19 cm respectively. The coronal correction rates at time B and C were 39.19 ± 11.32% and 60.77 ± 12.14%. The sagittal correction rates at time B and C were 27.38 ± 13.70% and 50.73 ± 13.94%.
ConclusionsThe three-staged treatment achieves significant spinal correction without 3-column osteotomy and addressing type I SCM in cases of extremely severe CS with Type I SCM.
