3. Stunted growth
There are singular exostosis and multiple exostoses. Generally, exostoses are inherited from the parents and are evident at birth. Those who suffer from multiple exostoses will develop several growths on various bones in their body. There are cases of multiple exostoses that occur that are not inherited. The growths will start in early childhood and continue until natural bone growth ceases at the height of physical maturity. When afflicted with multiple exostoses, a person may suffer stunted growth or other abnormalities of the skeletal system.
During childhood, these extra protrusions of the bone can be painful and even alter the ability to move properly. Usually, multiple exostoses are benign and simply hamper proper bone growth. In rare cases, multiple exostoses may turn cancerous.
Depending on the location of the growths, surgical removal may be required to limit stunting or to allow regular movement. Growths do not return once surgically removed.
