Sonographische Kontrolle von Spongiosatransplantaten ?Unterst�tzung der radiologischen Diagnostik

Abstract

The x-ray control is standard for spongiosa substance plasty and shows three periods of healing. In the first two periods (vascularisation and osteogenic reaction) the examination is restricted. Ultrasound control is a simple handling method although a hyporesonance or non-resonance of calcareous bone exists. The follow-ups concerning spongiosa substance plasty are made by ultrasound and x-ray control, and more exact assessments are possible. Advantages and disadvantages of ultrasound in extremities are discussed.
