Radiographic findings of both hands at age 5 yr and 7 months. The bilateral short first metacarpals show large pseudoepiphyses. The middle phalanges of the second, third, and fifth fingers are short, with clinodactyly of the fifth fingers. The fourth fingers are unaffected. The proximal phalanges of both third fingers are short. Note the segmentation anomaly with accessory ossification along the proximal phalanx and an accessory ivory dense epiphysis at the base of the distal phalanx of the left third finger. Note the ulnar deviation of the left second finger and radial curvature of the third finger. The carpal bone age is retarded.Abbreviations: Rt, right; Lt, left.
