Confirming a Diagnosis

How is skeletal dysplasia diagnosed?

Some forms of skeletal dysplasia may be seen before a child is born. In those cases, the doctor may make an initial diagnosis of skeletal dysplasia based on an ultrasound. After birth, the most common way doctors diagnose skeletal dysplasia is through a skeletal survey, or a series of X-rays of the body. However, X-rays do not always provide a complete picture of a child’s diagnosis.

DID YOU KNOW?

A skeletal survey alone misses a clear diagnosis in 30% of skeletal dysplasia cases.

Some types of skeletal dysplasia can look very similar to one another on an X-ray image.

Why is skeletal dysplasia difficult to diagnose?

Patients can often go years without a complete diagnosis. Without additional testing, skeletal dysplasia can be difficult to fully diagnose and can often go underdiagnosed for several years. This can interfere with a child getting the right management plan for their specific type of skeletal dysplasia.

Let’s look at some of the reasons why skeletal dysplasia can be challenging to diagnose:

There are more than 450 types of skeletal dysplasia, from common types like achondroplasia to less common forms like spondyloepiphyseal dysplasia congenita.

Many of these disorders have overlapping signs and symptoms, and some may occur at the same time as other skeletal conditions like bilateral Legg-Calvé-Perthes disease.

It can be difficult to pinpoint the underlying cause and the specific type of skeletal dysplasia without testing.

For these reasons, reaching a confirmed diagnosis can take years for some children, making it difficult to choose the right path forward.
