Congenital postural deformity association.

Abstract

The so-called congenital postural deformities were evaluated in the material of the Hungarian Congenital Malformation Registry, 1970-1976. Seven categories of postural deformities: dislocation of the hip, clubfoot, torticollis, musculoskeletal, other limb, face-nose and auricular were separated. The occurrence of the combination of dislocation of the hip, clubfoot and torticollis is manifold of random combination. These three postural deformities, however, are not associated more often with other nonpostural type abnormalities. Thus the congenital postural deformity association composed of two or more combinations of dislocation of the hip, clubfoot and torticollis without other major congenital abnormalities is treated as a provisional entity. Its birth prevalence is 0.4 per 1000 total births thus after Down syndrome it is the second common type of multiple congenital abnormalities. The aetiology and its higher sib-occurrence are explained by intrauterine maternal moulding factors.
