Hyperphalangism accompanied by brachydactyly of the feet: a case report

Asymptomatic symmetrical hyperphalangism of the fingers accompanied by foot anomalies is very rare. We present a 21-year-old man with anomalies in both hands and feet. He had short little, index, and middle fingers, long ring fingers, and clinodactyly of the little finger. He also had symmetrical brachydactyly of both feet. There were no other skeletal anomalies and his family members were normal. Radiographic examination of the hand showed oblique articulation of the metacarpophalangeal joint of the index finger with ulnar deviation, hyperphalangism of the middle finger, brachydactyly of the middle phalanx of the little finger, and long proximal phalanx of the ring finger. Foot radiography showed dysplastic middle phalanx of the middle toe, with the remaining lesser toes having only two phalanges. The two feet were radiographically similar except for a dysplastic middle phalanx in the second and third toes of the right foot. Since the patient was not physically challenged, no treatment was offered.
