One of the worlds shortest models Mary Russell at 4 feet 1 inch with 6 foot model Georgia Meacham in London, UK on June 16, 2016. The 4ft1 beauty suffers with achondroplasia a medical term for dwarfism, which means she has as average sized torso but short arms and short legs, with an oversized head. As well as stifled growth, Mary also suffers with sciatica and spinal stenosis, an abnormal narrowing of the spinal canal – which cause agonising nerve problems, leaving her in excruciating pain and unable to stand for long periods of time. The condition leaves Mary, 47, struggling with everyday tasks things most people take for granted like going to the supermarket, getting cash from an ATM and ordering a drink at a bar become a challenge.
