[Complications of the finger osteosynthesis using Kirschner's wires in arterial inflow disorder]

At an osteosynthesis of Kirshner wires to one of widespread complications is their spontaneous migration that leads to formation of bone deformation or to necessity of application of less effective kinds of an immobilization. In posttraumatic change of arterial inflow to hand and fingers leads to an oxygen level reduction in tissues, their chronic ischemia and to increase of a lactate and pyruvate contents in peripheral blood that can influence on Kirshner wires. Spontaneous migration of Kirshner wires from bones of fingers and decrease of their fixing in the bones is characteristic for patients with the expressed posttraumatic infringement of arterial inflow. This phenomenon can be explained, in particular, of acidity of peripheral blood change owing to considerable reduction arterial blood flow and secondary changes in bone and metal pin contact surface.
