Tibia Vara OMIM

Description: TIBIA VARA Alternative titles; symbols BLOUNT DISEASE OSTEOCHONDROSIS DEFORMANS TIBIAE TEXT Little is known about this condition which bears some similarity to osteochondritis of various sites (165800) and which may be heterogeneous. Blount (1937) suggested the existence of an infantile type with onset in the first year or two of life and an adolescent type developing just before puberty. The report by Blount (1937) concerned 22 cases of bowlegs in infants, with progressive deformity and radiologic findings of sloping proximal tibial epiphysis and a medial beak of the metaphysis. The description by Tobin (1957) of tibia vara beginning at puberty with osteochondritis dissecans of the knees in father and 2 sons strengthens the view that the 2 disorders are fundamentally identical.
