Radiologic Features of Achondroplasia

Abstract

It would be appropriate to begin with a photograph of a miniature bronze statue of an ancient Roman who is believed to represent one of the dwarfed gladiators assembled by the emperor Domitian almost two thousand years ago. The skill of the unknown artist clearly defined the clinical features of an achondroplastic dwarf as they have been presented by Professor Maroteaux. Had we an opportunity to examine this individual radiographically, we should have found him to have short and relatively thick tubular bones in all limbs. The femur would not be much longer than the tibia. This feature and similar proportions in the bones of the upper limb (Fig. 1) are responsible for the diagnostically important rhizomelic limb shortening that characterizes achondroplasia. The tuberosities to which muscles are attached are unusually prominent, and together with relatively large articulating ends of the bones exaggerate the discrepancy between length and width of the shafts.
