This paper presented a special case and shortly described the congenital malformations of a child operated at the age of 2 years and 7 months. Medical literature does not mention the cases of double or triple congenital scoliosis. 54 patients were treated, out of whom, 39 were operated during the period of 2000 and 2012. This series presented 4 patients with double congenital scoliosis and 2 with triple congenital scoliosis. All these axial deviations were due to hemivertebrae with longitudinal imbalance of the spine, if these hemivertebrae were present on a distance of at least 5 normal vertebrae.
Keywords: congenital double scoliosis; growth guiding; posterior hemivertebral spongious enucleation; supernumerary hemivertebra; supernumerary vertebra.
