Kniest Dysplasia

  • Harold Chen
Living reference work entry


In 1952, Kniest (1952) described an unusual form of disproportional dwarfism, called “atypical chondrodystrophy.” Kniest dysplasia is a type II collagenopathy with characteristic clinical, radiographic, and histological findings. Kniest dysplasia is distinguished by platyspondyly and delay in ossification of the proximal epiphyses. After ossification, the epiphyses are enlarged resulting in dumbbell-shaped long bones.
