Principles of rational correction of leg improper position in patients with tibial aplasia

Чегуров О.К., Макушин В.Д.

Abstract


Using a method of mathematical modelling it is established, that correction of leg flexion position about the axis, passing through the centre of fibular head, is the most rational way in patients with tibial aplasia. One has occasion to run into the congenitally shortened rigid soft-tissue component only, while correcting leg improper position in patients with tibial aplasia. Its rheological properties allow leg extension with higher daily rate of distraction - 5-6 mm. Clinically it is necessary to calculate Rb/Ra value after their measurement in apparatus-limb system preliminarily after the apparatus application for the purpose of distraction rate determination.
