<p>Walking is the first manner of displacement for human and essential for daily life activities. The human gait can be analyzed from several points of view and specialization. The Ilizarov frame is an external fixation device, primarily used for the treatment of complex fractures which adversely affects the functional state of the locomotor system. The objective of this paper was to analyses the spatiotemporal parameters of gait during treatment by the Ilizarov technique.  <strong>Materials and methods:</strong>  The study consists of 6 males with lower limb injuries performed walking trials, with and without the Ilizarov frame. Gait analysis was carried out using a camera and Kinovea application. <strong>Results:</strong> walking speed (p = 0.385), stride length (p =0.325), cadence (p = 0.641), stance time of operated limb (p = 0.265), swing time of operated limb (p = 0.959), double support time of operated limb (p=0.227) respectively were all no important difference with Ilizarov and without it. The times (stance, swing, and double support) (p=0.018) for non-operated limb have significantly different with Ilizarov.</p>

Gait analysis can be described as a field of biomechanical engineering dealing with the subject of human locomotion. This study aimed to identify the effect of Ilizarov on gait when the presence the above-knee prosthesis. The study was made on a 50-year-old male patient was underwent correction right tibia with Ilizarov fixation due to war accident in July 2012. Also, this accident led to trans-femoral amputation. Two-dimensional gait system of a synchronized 25 Hz camera with an AMTI force platform was use for measuring gait kinematics and kinetics data while walking at a self-selected speed. These data can be used as standard measures in pathology studies, as input to theoretical joint models, and as input to mechanical joint simulators treated with Ilizarov and prosthetics.
