What is ankle Dysplasia?
Dysplasia epiphysealis hemimelica (DEH), also known as Trevor’s disease, is a rare developmental disorder affecting the epiphyses; in young children, it usually involves the knee and ankle joints. DEH was first reported by Mouchet and Belot in 1926,1 who named it tarso megalia.

What is multiple epiphyseal dysplasia?
Multiple epiphyseal dysplasia is a condition that affects the ends of the long bones, otherwise known as epiphysis. The condition results from a problem in the cartilage oligomeric matrix protein, which accumulates in the cartilage and causes premature destruction, and can lead to early arthritis.
What is atavistic epiphysis?
Atavistic epiphysis: A bone that is independent phylogenetically but is now fused with another bone. These types of fused bones are called atavistic, e.g., the coracoid process of the scapula, which has been fused in humans, but is separate in four-legged animals.
How common is trevors disease?
Is Trevor’s disease hereditary?
Dysplasia epiphysealis hemimelica (DEH), also known as Trevor disease, is an extremely rare, non-hereditary disease that is characterised by osteochondromas arising from the epiphyses.
When does elbow dysplasia show up?
The most common age when the signs are first seen is between 6 and 10 months of age, but some dogs only present as middle aged or older adults when they have advanced arthritis.
Is there treatment for multiple epiphyseal dysplasia?
Multiple Epiphyseal Dysplasia Treatment Realignment surgery of the hips. Guided growth of the lower extremities (hemiepiphysiodesis) to help correct deformities. Osteotomies for severe deformities of the lower extremities as the patient matures. Excision of patella if there is a double layer and it is causing pain.
Is multiple epiphyseal dysplasia painful?
There are two types of multiple epiphyseal dysplasia, which can be distinguished by their pattern of inheritance. Both the dominant and recessive types have relatively mild signs and symptoms, including joint pain that most commonly affects the hips and knees, early-onset arthritis, and a waddling walk.
