What is Dysplasia Epiphysealis Hemimelica / Trevor Disease

Dysplasia Epiphysealis Hemimelica, also known as Trevor Disease, is a rare developmental bone disorder that primarily affects children. It is characterized by an abnormal overgrowth of cartilage within the epiphysis (the end part) of long bones, typically in the lower extremities.

Trevor Disease usually presents unilaterally, affecting only one side of the body. The condition commonly manifests in the ankle, but can also occur in the knee, hip, or other joints. Symptoms may include pain, swelling, limited range of motion, and deformities.

The exact cause of this condition is unknown, and it is not typically hereditary. While the growth abnormalities associated with Trevor Disease can cause functional impairments, the condition is generally benign and non-life-threatening. However, in some cases, surgical intervention may be necessary to address severe symptoms or correct deformities.

Diagnosis of Dysplasia Epiphysealis Hemimelica is typically made through imaging techniques such as X-rays or MRI scans, which reveal the characteristic bone and cartilage abnormalities. Treatment options may include pain management, physical therapy, and in more severe cases, surgical interventions.
