-
- Epiphysealis Hemimelica Dysplasia is a disorder that affects bone joints.
- It is characterized by overgrowth of the cartilage on the end (epiphysis) of
- one or more of the long bones (carpal or tarsal bones) in the hand or foot.
- Less often, the cartilage on other bones such as those in the ankle, knee or
- hip joint can be affected. Usually only one limb is involved. The limbs may
- be unequal in length.
-
- Symptoms
-
- Symptoms of Epiphysealis Hemimelica Dysplasia usually start between ages 2
- and 4 years. The cartilage on the end of one or more of the long bones in
- the hand or foot grows excessively, causing pain and discomfort. Less often,
- the cartilage on bones in the ankle, knee or hip joints can also be affected.
- Usually only one limb is involved and the limbs may be unequal in length.
-
- Causes
-
- The exact cause of Epiphysealis Hemimelica Dysplasia is not known. The
- disorder can occur in varying degrees within a family, but no pattern of
- inheritance has been determined.
-
- Affected Population
-
- Epiphysealis Hemimelica Dysplasia is a rare disorder predominantly affecting
- males. Symptoms usually first appear between the ages of 2 and 4 years.
-
- Related Disorders
-
- Chondrodysplasia Punctata is a form of disproportionate dwarfism,
- characterized by a pug nose, scaly skin lesions, and abnormalities in the
- cartilage on the ends of long bones.
-
- Conradi-Hunermann Syndrome is a rare inherited form of Chondrodysplasia
- Punctata, affecting infants and young children. This disorder is
- characterized by mild to moderate growth deficiencies and unusual facial
- features. Large skin pores and sparse coarse hair may also be symptomatic of
- this condition. (For more information, choose "Conradi-Hunermann" as your
- search term in the Rare Disease Database.)
-
- Therapies: Standard
-
- Treatment of Epiphysealis Hemimelica Dysplasia consists of surgically
- removing the overgrowths of cartilage in joints where it causes pain and
- discomfort. Other treatment is symptomatic and supportive.
-
- Therapies: Investigational
