Postaxial acrofacial dysostosis (POADS) is a type of acrofacial dysostosis (see this term) characterised by mandibular and malar hypoplasia, small and cup-shaped ears, lower lid ectropion, and symmetrical postaxial limb deficiencies with absence of the fifth digital ray and ulnar hypoplasia.

Cone-shaped epiphyses (also known as coned epiphyses) are epiphyses that invaginate into cupped metaphyses. That is, the epiphysis has a cone-shaped distal extension resulting from increased growth of the central portion of the epiphysis relative to its periphery.
