Thoracomelic dysplasia is an extremely rare primary bone dysplasia disorder characterized by a bell-shaped thorax, disproportionate short stature, pelvic hypoplasia, dislocatable radial heads and elongated distal fibulae. No acetabular spurs nor phalangeal cone-shaped epiphyses are present and osseous manifestations tend to normalize with age. There have been no further descriptions in the literature since 1988.
