The Influence of Pin Deviation on the Fracture Correction and the Fixator Adjustment with Sensitivity and Kinematic Analysis

Figure 1

(a) Kinematic model of bone and fixator system, “A”—distal bone; “1”—distal pin; “2”—distal pin clamp; “3”—the telescoping mechanism; “4”—proximal pin clamp; “5”—proximal pin; “B”—proximal bone. (b): The physical model of fixator and bone system, ==75mm; ==30mm; ==65mm; D=90mm; “, ”— two rotational variables near distal bone, “  , ”—three rotational variables near proximal bone; “d”—translational variable; “, , ”—angle deviations of pin; “, , ”— position deviations of pin.
