The Authors describe a pair of male twins, aged 17, with concordant congenital clockwise torticollis, and two single-born sibs, one male aged 15 and one female aged 17, with concordant congenital counter clockwise torticollis. X rays show that in these cases the organic basis of torticollis is the wedgelike deformation of one or two cervical vertebrae. Other bone malformation are observed in the spines of the propositi and in the twins' mother.

The Authors believe that congenital osseous torticollis is part of a hereditary malformation of the axial skeleton; this malformation may be of two types, one “dysmorphic” (as the cases here described) and one “schisosynostotic” as in the twin case described by Gedda and Iannaccone in 1957.
