Recessive Multiple Epiphyseal Dysplasia

What is Recessive Multiple Epiphyseal Dysplasia?

Recessive multiple epiphyseal dysplasia (rMED) is an inherited disease that causes bone deformities and joint pain. Unlike people with related diseases, those with rMED typically reach normal height and live normal lifespans.

Half of people with rMED are born with an obvious bone abnormality such as cleft palate, club foot, or an inwardly-curved pinky finger. Some also have a mild curvature of the spine (scoliosis).

All people with the disease develop joint pain, often late in childhood. Pain is most common in the hips and knees but can also occur in the wrists, fingers, and elsewhere.

How common is Recessive Multiple Epiphyseal Dysplasia?

It is unknown how many children are affected by recessive multiple epiphyseal dysplasia. Researchers believe it may be more common than realized due to people with mild symptoms who go undiagnosed.

How is Recessive Multiple Epiphyseal Dysplasia treated?

Recessive multiple epiphyseal dysplasia is usually treated through a combination of targeted muscle strengthening exercises and non-steroidal anti-inflammatory drugs (NSAIDs). People with the disease should avoid sports and activities that stress their joints. Obesity too can put strain on the joints. In some circumstances, surgery may be useful.

What is the prognosis for a person with Recessive Multiple Epiphyseal Dysplasia?

People with recessive multiple epiphyseal dysplasia can live normal lifepans and can perform most daily activities, provided these don't stress the joints. Despite joint pain and some bone and joint abnormalities, people with rMED can live normal, healthy lives.
