multiple epiphyseal dysplasia

Multiple epiphyseal dysplasia (also known as dysplasia epiphysealis multiplex or Fairbank disease) is a type of non-rhizomelic dwarfism characterized by flattening and fragmentation of epiphyses.


Multiple epiphyseal dysplasia is inherited in an autosomal dominant pattern.

Radiographic features

  • delayed and irregular secondary ossification centers
  • flattened and squared-off epiphyses 
  • thinning of the lateral tibial epiphysis
  • double-layered patella
  • hypoplastic tibial and femoral condyles with shallow intercondylar notch
