Blount's disease. Blount's disease is a growth disorder of the tibia (shin bone) that causes the lower leg to angle inward, resembling a bowleg. It is also known as tibia vara. It is named after Walter Putnam Blount (1900â1992), an American pediatric orthopedic surgeon.
The cause is unknown. It is thought to be due to the effects of weight on the growth plate. The inner part of the shin bone, just below the knee, fails to develop normally. Unlike bowlegs, which tend to straighten as the child develops, Blount's disease slowly gets worse. It can cause severe bowing of one or both legs.
