One such example is the presence of cone shaped epiphyses.7 In most instances, cone shaped epiphyses represent the initial stage of premature epimetaphyseal fusion resulting in growth arrest and shortening of the bone involved. Analysis of the site and shape of cone shaped epiphyses, in particular of the phalanges, can be helpful in the diagnosis of skeletal dysplasias.8–10Based on the observation of four patients, we delineate a new skeletal dysplasia with autosomal recessive inheritance. Because all cases show cone shaped epiphyses in the hands and a radiographically characteristic involvement of the proximal femoral epiphyses, we propose naming this condition acrocapitofemoral dysplasia. Patient 1 Patient 1 was referred at the age of 9.5 years with the tentative diagnosis of hypochondroplasia. She was born at 34 weeks’ gestation with a birth weight of 2470 g (50th centile) and length of 47 cm (50th-90th centile). The pregnancy was uncomplicated and the delivery uneventful. Around the age of 7 years, short stature was noted. She had normal psychomotor development but experienced emotional problems related to her short stature. The parents are healthy but consanguineous (fig 1A). The father measures 166 cm and the mother 163 cm. A younger sister is also healthy and has a normal height. Physical examination at the age of 9 years 6 months showed short stature with height … ER -
