Hereditary congenital posterior dislocation of radial heads.
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 nail-patella syndrome. This family confirms the autosomal dominant inheritance of congenital posterior dislocation of radial heads.
