Dysplasia epiphysealis hemimelica (DEH), or Trevor disease, is a rare developmental disorder affecting the epiphyses in young children. The first report of DEH in the literature was by Mouchet and Belt in 1926, who described the condition as a tarsal bone disorder and used the term tarsomegalie. In 1950, Trevor...

a/k/a: craniometaphyseal dysplasia
* autosomal recessive
* failure of modeling of cylindrical bones
* "Erlenmeyer flask" appearance of metaepiphyses

CONCLUSION: Although multiple epiphyseal dysplasia is a disease of childhood, it is seldom severe enough to require operative intervention in the initial 2 decades of life.

Objectives
1. Describe clinical features suggestive of MED
2. Describe orthopaedic problems related to MED
3. Describe a method of obtaining immediate further information on the osteochondrodysplasias

* autosomal recessive
* dense, sclerotic bones [Cf: osteopetrosis (sporadic, not inherited)]
Features:
* open cranial sutures + fontanelles
* Wormian bones
* dolichocephaly
* sclerotic vertebrae
* fractured long bones
* short, stubby hands
* partial agenesis/aplasia of terminal phalanges [simulates acro-osteolysis]

Dyschondroplasia and dysplasia involving epiphyseal plate
The grouping comprises those congenital conditions that are associated with persistence or metaplasia of the original bone matrix to form rests of cartilage within or on the surface of a bone. The listing includes: Diaphyseal aclasis, Dysplasia epiphysialis hemimelica, enchondromatosis and its variants. I have...

Clinical presentation of a 70 year old woman with spondylo-epiphyseal dysplasia who has had severe limitation of her right shoulder motion since birth. Over the last few years she has progressively experienced severe pain which prevents her from using this arm and from sleeping. She also uses a wheel chair...

Although many dysplasias are quite rare, some occur with sufficient frequency that most general practice radiologists will see them and should know something about them. This chapter gives an extremely simplified meatball approach to the diagnosis of these more common disorders. You won't find rare syndromes such as bird-headed dwarvism...
