Sibs with a disorder resembling Blount disease (tibia vara)

Pediatr Radiol. 1991;21(4):316-8. doi: 10.1007/BF02018639.


Radiographic investigation of 3 Turkish sibs presenting with bowed legs disclosed physiological tibial bowing in the 7-month-old girl. Stage I Blount disease in the 26 month-old boy and Stage II Blount disease in the 45 month-old girl. The reported cases provide evidence for autosomal recessive inheritance. This observation points to genetic heterogenity, i.e. the existence of 2 genetically different, but radiologically indistinguishable disorders.
