join together too early. This happens before the baby's brain is fully formed. As the baby's brain grows, the skull can become more misshapen. The spaces between a typical baby's skull bones are filled with flexible material and called sutures.

or to permanent brain damage. If not treated, most forms of craniosynostosis can have very serious results, including death.

tissue. Over time, the disease can cause affected bones to become fragile and misshapen. Paget's disease of bone most commonly occurs in the pelvis, skull, spine and legs.

medications, pain medications, and medications that slow the rate of bone turnover, decreasing the activity of Paget's disease.

thin and flexible. Constant pressure in one area of the

skull can change the skull's shape. This condition is called positional plagiocephaly (skull molding) and is one of the most common forms of abnormal head shapes. Babies with plagiocephaly often have noticeable flatness on the back or sides of their head, and there is typically little hair in those areas. 

is a very rare skeletal condition of unknown cause, characterized

by the uncontrolled proliferation of distended, thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement.
