Effect of Wire Tension on Rate of Weight Bearing in Ilizarov Apparatus| Biomed Grid

K-wires play an important role in stability of Ilizarov fixator. In this fixation system, wires are tensioned for bearing patient weight. In this study, measuring of vertical bending of k-wire would show the effect of horizontal tension of wire. Russian Ilizarov K-wires were inserted into artificial tibia sawbones and fixed on the ring. Then, after wire tensions in range of 70kg to 130kg by tensioner device and vertical forces of 40kg to 100kg by bending test device, vertical displacements were measured. 49 data about to wire displacements are recorded. in the minimum horizontal tension (P) (70 kg) and maximum vertical loading (F) (100 kg), the rate of vertical displacement (Y) received to the highest amount (0.837 cm), but in condition that P was maximum (130 kg) and F was minimum (40 kg) the amount of Y got to the lowest point (0.112). Regarding to the obtain data, effect of k-wire tensile on decreasing the vertical displacement and prevent from k-wire cutting is obviously Figure out. More tension is better way to earning stability. This should be noted; the maximum amount of tension is the half of yield point
