The limbs may also be abnormally short. The teratogen thalidomide, a drug used to treat morning sickness, was shown in the 1960s to cause a number of arm and leg abnormalities in newborn babies. </p><p>A number of other limb abnormalities can arise during pregnancy. These are rare, and can be corrected to some extent by different techniques including surgery. </p><h3>Club foot</h3><p>This is an abnormality where the front part of the foot turns toward the inside of the heel. Club foot is treated with physiotherapy, which involves gentle stretching to reshape the position of the foot. The foot is stretched and then placed in a cast or special boot for a few weeks. The cast is removed, the foot stretched a bit further, and the cast is put in place for another few weeks. This process continues over a long period. In some cases, surgery is needed. </p><h3>Congenital hip dislocation</h3><p>This is when the hip bone and thigh bone are underdeveloped, which leads to dislocation of the hip. Treatment involves holding the hips in place so that they can continue to develop properly. This can be accomplished through the use of splints, harnesses, and sometimes surgery. </p><h3>Polydactyly</h3><p>This is the presence of extra fingers or toes. This condition can be corrected with surgery to remove the extra finger or toe. </p><h3>Syndactyly</h3><p>This is fusion of one or more fingers or toes. Surgery is useful to separate the fingers or toes, and to add skin to the places where it is needed. </p><h3>Cleft hand and cleft foot</h3><p>These are very rare conditions where the separation between the third and fourth fingers or toes extends deep into the hand or foot. Plastic surgery may be needed to help correct this abnormality. </p><h2>Skull abnormalities</h2><p>Many abnormalities of the brain are caused by neural tube defects. These abnormalities can lead to problems with the development of the skull. Studies have shown that neural tube defects can be prevented if the mother takes folic acid before and during her pregnancy. </p><h3>Anencephaly</h3><p>This is the absence of a major part of the brain, skull, and scalp. A baby born with anencephaly is usually blind, deaf, unconscious, and unable to feel pain. they may still be able to breathe and respond to sound or touch. The prognosis for babies born with anencephaly is extremely poor, and there is no corrective surgery for this congenital abnormality. Usually the baby is stillborn or dies soon after birth. </p><h3>Encephalocele</h3><p>This is a condition where parts of the brain protrude in a sac through openings in the skull. Usually, encephaloceles are dramatic deformities associated with neurological problems. They are usually associated with abnormalities of the brain, skull, and face, and other problems. </p><h3>Microcephaly</h3><p>This condition, where the child has an unusually small brain and skull, is often associated with developmental disability.</p>https://assets.aboutkidshealth.ca/AKHAssets/skeletal_disorders.jpgSkeletal disorders
