Abstract

We report on 4 patients with congenital posterior dislocation of radial heads in 3 generations of a family. Radiographs of the elbow joints of 3 individuals are presented. All affected subjects have mild limitation of extension and a strong restriction of rotation in the elbows. Comparison with previously described patients shows similarities in the X-ray findings. Congenital posterior dislocation of the radial head can be unilateral or bilateral. This malformation is also found in patients with antecubital pterygium or nailpatella syndrome. This family confirms the autosomal dominant inheritance of congenital posterior dislocation of radial heads. © 1995 Wiley-Liss, Inc.
