Characteristic features of hemodynamics in femoral neck of children with femoral head aseptic necrosis

Abstract

Purpose To study the characteristic features of femoral neck blood circulation in children with femoral head ischemic defects of traumatic and dysplastic genesis. Materials and methods The authors analyzed rheovasography results of 17 patients with the ischemic femoral head defects developed due to posttraumatic aseptic necrosis (Group 1, n=9) and Legg-Calve-Perthes disease (Group 2, n=8). The measurements were performed before surgery, after tunnel perforation of the neck, and after cell-and-tissue transplantation. Results More marked changes in the parameters of pulse blood filling were recorded in Group 2 and corresponded to the state of decompensation ischemia that might be associated with the disorders of venous blood outflow. Conclusion The results confirm the feasibility of re-interventions that stimulate hemodynamics and the use of a prolonged stimulation with wires in order to achieve the draining effect.
