Dysplasia epiphysealis hemimelica (DEH) is a rare, non-hereditary, non-inflammatory disorder of the growth plate of the long bones. It is characterized by the presence of multiple, symmetrical, ossified, cartilaginous nodules at the epiphyses of the long bones. These nodules can cause deformity of the affected bones, and can lead to pain and limited range of motion. Treatment is usually not necessary, but in some cases, surgery may be recommended to correct the deformity.

The most common symptoms of Dysplasia Epiphysealis Hemimelica (DEH) are:

-Pain in the affected joint
-Swelling of the affected joint
-Limited range of motion in the affected joint
-A bump or lump on the affected joint
-A deformity of the affected joint
-A feeling of instability in the affected joint
-A feeling of grinding or clicking in the affected joint

The exact cause of Dysplasia Epiphysealis Hemimelica (DEH) is unknown. However, it is believed to be caused by a combination of genetic and environmental factors. Some researchers believe that DEH is caused by a mutation in the gene that controls the growth of cartilage. Other possible causes include trauma, infection, and hormonal imbalances.

1. Observation: In some cases, no treatment is necessary and the condition may resolve on its own.

2. Physical Therapy: Physical therapy may be recommended to help improve range of motion and strength in the affected joint.

3. Surgery: Surgery may be recommended in cases where the condition is causing pain or functional impairment. Surgery may involve removing the extra bone growth or reshaping the affected joint.

4. Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to help reduce pain and inflammation.

1. Genetic predisposition: Dysplasia Epiphysealis Hemimelica (DEH) is thought to be an inherited disorder, although the exact genetic cause is unknown.

2. Age: DEH is most commonly seen in children between the ages of 5 and 10.

3. Gender: DEH is more common in males than females.

4. Trauma: Trauma to the affected area may increase the risk of developing DEH.

5. Certain medical conditions: Certain medical conditions, such as Ehlers-Danlos syndrome, may increase the risk of developing DEH.

At this time, there is no known cure for Dysplasia Epiphysealis Hemimelica (DEH). Treatment typically involves pain management and physical therapy to help manage symptoms. Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids may be prescribed to reduce inflammation and pain. Surgery may be recommended in some cases to correct any deformities or to remove any loose fragments of bone.
