According to the literature data incomplete restoration of the muscular strength is observed after malleolar fractures that made us evaluate the contractile capacity of the tibial muscles after treatment of 59 adult patients with these fractures using Ilizarov method. Additionally, late follow-up of 5 cases were examined in complex. Practically, full restoration of the anatomical sizes, electrogenesis and contractile property of the tibial muscles is possible in the interval from 5 to 8 years after treatment that can be explained by fine reduction and reliable fixation of the bone fragments during treatment and increase of neuro-motor apparatus sensitivity to the specific impacts while muscles' work in the conditions of habitual motor activity.
