Functional status of patients with the lower limb varus deformity of different etiology

A comparative physiological and biomechanical study of 19 patients with phosphate diabetes (PD) and 44 patients with the lower limb varus deformities without PD has been performed. The retardation of body longitudinal growth, the decrease in limb muscle contractility, locomotion velocity- and force-related characteristics, capacity for work was revealed in patients with PD. The moderate decrease in the muscle strength of the leg deformed, the weakening of foot balancing function and the decrease of loading foot parts in walking was observed in patients without PD.
