Hereditary Multiple Exostoses
What are the symptoms?
Exostoses grow throughout childhood, but usually become fully bony and stop growing at the end of teenage years. When they grow large they are frequently painful and can disturb growth resulting in variable short stature and deformity. Less commonly symptoms occur when exostoses compress adjacent nerves and vessels. Forearm pain, hip, knee and walking problems may occur and flat foot may also exist. Extremely rarely exostoses may become cancerous (less than five per cent of individuals). Rapidly-growing and painful exostoses in late adolescence or adulthood with a cartilage-cap thickness in excess of 10mm are usually those with this potential. Disease severity can range from mild to severe even within families.
