This young infant was born with a chromosomal abnormality known as rocker-bottom foot, which is a musculoskeletal deformity that manifests in cases of trisomy 13, or Patau syndrome, trisomy 18, or Edwards syndrome, and trisomy 9. The word trisomy means that there are three copies of the respective chromosome in each, and every cell of the person’s body, rather than the normal two. Rocker-bottom foot is due to an enlarged heel bone, or calcaneus, and a pronounced convexity to the plantar surface, or sole of the foot. Rocker-bottom foot is also known as, congenital vertical talus.
