Method of determining the varus deformity angle in Blount's disease to children

摘要

The inventions relates to medicine, particularly to children's orthopedics.Summary of the invention consists in the fact that it is made the radiography of the lower extremity at the front, from the knee joint up to the midthird of the shin. Then, according to the obtained skiagram it is determined the medium diaphysial and proximal epiphysial axis, as well as the axis of the tibia proximal physial zone. After what, the varus deformity angle is calculated according to the following formula:K = (90° - a) + b,where:K is the angle of the varus deformity,90° - the angle between the tibia medium diaphysial axis and the axis of the tibia proximal physial zone to normal,a - the angle between the tibia medium diaphysial axis and the axis of the tibia proximal physial zone on the skiagram,b - the angle between the tibia medium diaphysial axis and the axis of the tibia proximal epiphysial zone on the skiagram.
