Positional plagiocephaly

Plagiocephaly is a disorder that affects the skull, making the back or side of a baby’s head appear flattened. It is sometimes called deformational plagiocephaly. This pageexplains positional plagiocephaly and what to expect when a child comes to Great Ormond Street Hospital for treatment.

Additional little fingers

This page explains about additional little fingers and how they can be corrected. The medical term for this is ‘ulnar polydactyly’. Ulnar polydactyly or having an additional little finger on one or both hands is very common, especially in certain ethnic groups.This information sheet from Great Ormond Street Hospital (GOSH) explains about additional little fingers and how they can be corrected.


Achondroplasia is the most common type of short limb (or disproportionately short stature). The condition affects how some of the bones develop, particularly the limb bones and specifically the upper arms and thighs. There are obvious problems with how some of the facial and skull bones grow, too.

Liver cancer

Liver cancer is rare in children and teenagers. The condition comes when cancer cells form in the tissues of the liver. Primary liver cancer is when the cancer starts to grow in the liver. Secondary liver cancer is when it has spread from another organ.


This information from Great Ormond Street Hospital (GOSH) explains achalasia. The oesophagus (foodpipe) contains muscles which squeeze rhythmically to push food downwards. In achalasia, these muscles and the lower sphincter (ring of muscle at the end of the oesophagus) do not work properly so food cannot pass easily into the stomach to be digested.
