Rheograms of the shin have shown a decrease and asymmetry of the specific blood flow, less elasticity of arteries, less velocity of their blood filling in patients with malformations of the fibular bone. At early terms after reconstructive operations the elasticity of arteries improved, the arterial tone decreased, the velocity of blood filling of the arteries on the shin operated upon increased. At later terms the parameters of elasticity and venous outflow remained normal, the arterial distension increased.
