[Functional state of lower extremities muscles at the patients with shin congenital defects before and after treatment with Ilizarov device].

Results of examination (dynamometry, electromyography, ultrasonography) of 34 patients aged 6 to 23 years before and after treatment with Ilizarov's method are analyzed. Decrease of dynamometry and electromyography parameters, ultrasonic data are evidence of hard structural and functional disorders of motor system of these patients. Decrease of force and activation characteristics of tested muscles of operated extremity after removal of external fixator relates to high level of central protective inhibition and prolonged afferentation dysbalance at somatosensory system. Degree of recovery is limited and depends on patient age: recovery resources are presented at children before 8 years, but at juveniles they are depleted during the growth.
