An osseous projection from the midportion of the metaphysis of the distal phalanges of the digits was seen in 79% of untreated children with primary hypothyroidism. There is a significant difference (p less than .0005) in the incidence of this projection between children with primary hypothyroidism and those with idiopathic hypopituitarism or psychosocial dwarfism. The presence of this projection together with delayed skeletal should suggest primary hypothyroidism.
在79%未经治疗的原发性甲状腺功能减退症儿童中，可见指骨远端干骺端中部的骨性突起。原发性甲状腺功能减退症儿童与特发性垂体功能减退症或心理社会性侏儒症儿童相比，这种突起的发生率存在显著差异（p<0.0005）。这种突起的存在以及骨骼发育延迟应提示原发性甲状腺功能减退症。
