achondroplastic dwarf /-plas″tik/ , the most common type of dwarf, characterized by disproportionately short limbs, a normal-sized trunk, a large head with a depressed nasal bridge and small face, stubby hands, and lordosis. The condition results from an inherited defect in bone-forming tissue and is often associated with other defects or abnormalities, although there is usually no involvement of the central nervous system and intelligence is normal. See also achondroplasia.
