Transpedicular convex anterior hemiepiphysiodesis and posterior arthrodesis for progressive congenital scoliosis.

Nine children with progressive congenital scoliosis underwent bilateral posterior spinal fusion supplemented with transpedicular convex anterior hemiepiphysiodesis. The average preoperative curve was 52 degrees. The average age at surgery was 9 years and 1 month and the average follow-up period was 3 years and 6 months. Curve progression was arrested in all cases, and curve correction greater than 10 degrees was achieved in four patients.
