Abstract
- A 15-year-old boy presented with bilateral pain and stiffness in the hips, knees and ankles. He had been known for many years to have recessive multiple epiphyseal dysplasia (MED). Radiographs of the knees showed abnormally shaped knee epiphyses and a double-layered patella (DLP) consisting of anterior and posterior portions (Fig. 1, asterisks). Radiographs of the feet revealed short metatarsal bones and irregularly shaped tarsal bones with ossification. Additionally, there was a peculiar bony fusion of the sesamoid bones of the first toe bilaterally, resulting in a heart-shaped appearance (Fig. 2, arrows). MED is a heterogeneous group of skeletal dysplasias that may show an autosomal dominant or a recessive pattern of inheritance. Abnormalities of epiphyseal ossification are the hallmark of the disorder. DLP is highly diagnostic for recessive MED [1, 2]. The heart-shaped deformity of the sesamoid bones in MED has not been previously reported. The diagnostic significance of this sign remains to be established.
