Radiologische Diagnostik nach komplizierter distaler Radiusfraktur unter besonderer Berücksichtigung der Computertomographie

Abstract

After complicated distal radius fractures with persistent symptoms, a variety of radiological methods may be indicated, including plain films, magnification views, examination under stress and arthrography. CT accurately differentiates abnormalities of the distal radio-ulnar joint and aids in deciding on surgical treatment. Demonstration of degenerative changes and of subluxations is much more satisfactory in the third plane, since there is no superimposition.

Rotational deformity in malunited fractures of the distal radius

“…Measurements for radial torsion angle were performed using transverse scans as outlined by Frahm et al 15 At first, 2 transverse images were electronically summarized to 1 fusion image; the first scan was located 3 cm proximal to the fracture site and the second was distal to the fracture site at the height of the sigmoid notch of the radius. On the proximal position a tangential line was drawn to the volar cortical surface of the distal radius.…”

Die fehlverheilte distale Radiusfraktur - Biomechanik und operative Behandlungsmöglichkeiten

“…Diese Befunde sollten deshalb stets zur Veranlassung einer entsprechenden computertomografischen Untersuchung führen, die zwingend im Seitenvergleich erforderlich ist. Von den verschiedenen zur Bestimmung eines Rotationsfehlers beschriebenen Untersuchungsmethoden bevorzugen wir die Methode nach Frahm und Drescher [17]. Auch dem Griffelfortsatz der Elle sollte man auf den Nativröntgenaufnahmen Aufmerksamkeit schenken.…”
