Skeletal Dysplasia


Skeletal dysplasias are actually more than 380 conditions that involve abnormally developed bones and connective tissues. 

The word dysplasia has Latin roots meaning bad growth.


The specific symptoms will vary with the type of skeletal dysplasia and its cause. In general, skeletal dysplasia is associated with abnormalities in the size and shape of arms, legs, the trunk or the skull. As a result a person with skeletal dysplasia maybe unusually short with limbs that are out of proportion to the rest of the body.

Causes and Risk Factors for Skeletal Dysplasias

The causes of skeletal dysplasias can be due to many types of genetic abnormalities that are often difficult to determine as well as to treat. Skeletal dysplasias are caused by genetic mutations and can run in families. Often the disorders appear without any family history of skeletal dysplasia.


Skeletal dysplasias can be diagnosed by clinical, radiographic and/or pathological evaluation. Imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) scans can identify the bone abnormalities more precisely.


The skeletal dysplasia clinic at Cedars-Sinai Medical Center is a partnership of the Medical-Genetics Institute, Cedars-Sinai Orthopaedics and the Neurosurgical Institute.
