Cone-Shaped Epiphyses

Cone-shaped epiphyses (coned epiphyses) are epiphyses that invaginate into cupped metaphyses. They are more commonly found in the feet as a morphological variant, but can also be associated with symptoms or be seen with a variety of developmental disorders. Differential considerations for cone-shaped epiphyses include normal variant and ABCD MOST:
  • Normal variant (shown above in three different patients)
  • Achondroplasia, Acrodysostosis
  • Beckwith Wiedemann syndrome
  • Chondroplasia punctata, Cockayne syndrome, Conorenal syndrome (Mainzer-Saldino syndrome, association of chronic renal failure and phalangeal cone-shaped epiphyses of the hands), Cleidocranial dysplasia, Cartilage-hair hypoplasia
  • Dactylitis, Dyggve-Melchior-Clausen syndrome
  • Multiple epiphyseal dysplasia
  • Osteomyelitis
  • Sickle cell disease
  • Thermal injury, Trichorhinophalangeal syndrome
