What is Sirenomelia ? Sirenomelia, alternatively known as Mermaid Syndrome, is a very rare congenital deformity in which the legs are fused together, giving them the appearance of a mermaid's tail.
Causes of Sirenomelia : The causes of Sirenomelia are still unknown but research shows that it occurs due to the malfunctioning of the normal vascular supply from the lower aorta in utero.
Treatment: If the two legs were only fused through the skin and the three main bones are fully and correctly formed, surgery is used to separate the two legs. However, successful separation of the fused legs does not guarantee that the child will be able to walk normally. The child can survive as long as the vital organs are complete and fully functional,if two legs are completely joined the child has very little chance of survival.
