Stature and severity in multiple epiphyseal dysplasia

We investigated the stature and radiological findings in 15 patients with multiple epiphyseal dysplasia (MED). They were divided into normal-stature and short-stature groups according to their body height after 4 or 5 years of age. Their stature was not related to the involvement of the spine or epiphyses of long tubular bones except for the distal radius. Proximal phalanges and metacarpi were shorter in the short-stature group than in the normal-stature group, indicating that stature in MED had some relationship to the involvement of the wrist and hand. However, some patients in the normal-stature group showed involvement of distal radial epiphyses, and some patients in the short-stature group did not have stubby fingers. There are thus no clear-cut criteria to differentiate between the severe Fairbank type and the milder Ribbing type of MED.
