Multiple epiphyseal dysplasia (MED), also known as Fairbank's disease, is a rare genetic disorder (dominant form: 1 in 10,000 births) that affects the growing ends of bones. Long bones normally elongate by expansion of cartilage in the growth plate (epiphyseal plate) near their ends.
Early-onset diabetes mellitus with multiple epiphyseal dysplasia Radiograph of a WRS child presenting with dysplastic bone growth in various regions of the body. Wolcott–Rallison syndrome, WRS, is a rare, autosomal recessive disorder with infancy -onset diabetes mellitus , multiple epiphyseal dysplasia , osteopenia , mental retardation or ...
Autosomal recessive multiple epiphyseal dysplasia (ARMED), also called epiphyseal dysplasia, multiple, 4 (EDM4), multiple epiphyseal dysplasia with clubfoot or –with bilayered patellae, [1] is an autosomal recessive [2] congenital disorder affecting cartilage and bone development.
X-ray of the spine in a patient with spondyloepimetaphyseal dysplasia. Spondyloepiphyseal dysplasia congenita is one of a spectrum of skeletal disorders caused by mutations in the COL2A1 gene. [3] The protein made by this gene forms type II collagen, a molecule found mostly in cartilage and in the clear gel that fills the eyeball (the vitreous).
Treatment can involve operations to lengthen the leg bones, which involves many visits to the hospital. Other symptoms can be treated with medicine or surgery. Most female patients with the syndrome can live a long and normal life, while males have only survived in rare cases. [citation needed]
In 1956, the name "dysplasia epiphysealis hemimelica" was proposed by Fairbank. [1] The usual symptoms are the appearance of an osseous protuberance, on one side of the knee, ankle or foot joint which gradually increases Radiologically, [ 14 ] the condition shows a nonuniformity of growth and multiple unconnected ossification centers around the ...
Pseudoachondroplasia is caused by a heterozygous mutation in the gene encoding cartilage oligomeric matrix protein (COMP). Mutation in the COMP gene can also cause multiple epiphyseal dysplasia. Despite the radioclinical similarities between pseudoachondroplasia and multiple epiphyseal dysplasia, the latter is less severe. [3]
Achondroplasia is one of several congenital conditions with similar presentations, such as osteogenesis imperfecta, multiple epiphyseal dysplasia tarda, achondrogenesis, osteopetrosis, and thanatophoric dysplasia. This makes estimates of prevalence difficult, with changing and subjective diagnostic criteria over time.
