The full-length weight-bearing and AP (hip, knee, and ankle) radiographs demonstrate:
- full-length weight-bearing radiograph
- valgus knee deformity: the hip-knee-ankle angle (after correction) was a 1° on the right and 5° on the left
- hip
- bilateral acetabular dysplasia
- small femoral epiphyses
- irregular ossification centers of the greater trochanters
- shortening with enlargement of the femoral neck
- knee
- valgus left knee
- small ossification centers of the patellae with probably a double-layered patellae
- small and irregular tibial and fibular epiphyses
- hypoplasia of the lateral femoral condyles
- thinning of the lateral femoral epiphyses with irregular contours
- ankle
- small and irregular tibial and fibular epiphyses
- flattening with irregularity of the talar dome bilaterally
Case Discussion
Irregular and delayed ossification of multiple epiphyses with associated genu valgus in a patient with three of the siblings have the same anomalies are suggestive of Multiple epiphyseal dysplasias.
Multiple epiphyseal dysplasia also known as dysplasia epiphyseal multiplex or Fairbank disease) is inherited in an autosomal dominant pattern characterized by flattening and fragmentation of epiphyses.
