In four cases of congenital scoliosis in young children, due to a hemivertebra situated at or near the lumbodorsal junction, a functional cure has been accomplished by plaster-of-Paris corrective spicas. Anatomical cure by removal of the hemivertebra, as advocated by Compere, von Lackum and Smith, and Hibbs, is an unnecessary procedure in young children, since the non-operative method gives a perfect functional result despite the persistence of the hemivertebra.
