Achondroplasia is the most common type of short-limb disproportionate dwarfism. The term achondroplasia, implying absent cartilage formation, was first used by Parrot in 1878. Although the word achondroplasia is inaccurate from a histopathologic perspective, its use is universal and accepted by the International Working Group on Constitutional Diseases of the Bone.
