Primary External Fixation Versus Plaster Immobilization of the Intra-Articular Unstable Distal Radial Fracture in the Elderly
Primärer Fixateur externe versus Gipsruhigstellung bei älteren Patienten mit instabiler intraartikulärer distaler RadiusfrakturPublikationsverlauf

Zusammenfassung
Eine prospektive randomisierte Studie umfasste 32 ältere Patienten mit instabiler intraartikulärer distaler Radiusfraktur (AO C2 oder C3), um die Behandlung im primären Fixateur externe gegenüber der alleinigen Gipsruhigstellung zu vergleichen. Das radiologische Ergebnis in der Fixateurgruppe war signifikant besser, insbesondere konnten der radiokarpale Winkel und die radiale Inklination in dieser Gruppe wiederhergestellt und gehalten werden. Dagegen zeigten die funktionellen Ergebnisse nach sechs Wochen, drei Monaten und einem Jahr keinen statistisch signifikanten Unterschied zwischen beiden Behandlungsgruppen. Lediglich die durchschnittliche Volarflexion nach einem Jahr erwies sich in der Fixateurgruppe als besser. Drei schwerere Verlaufskomplikationen (eine persistierende Reflexdystrophie und zwei Dupuytrenkontrakturen) betrafen ausnahmslos die Fixateurgruppe. Obwohl die externe Fixation stabiler intraartikulärer distaler Radiusfrakturen bei älteren Patienten zu ausgezeichneten radiologischen Ergebnissen führt, können dabei bedeutsame Komplikationen auftreten, die funktionellen Ergebnisse sind dabei nicht besser als nach alleiniger Gipsbehandlung. Schlussfolgerung: Alleinige Gipsruhigstellung und primärer Fixateur externe sind gleichwertige Behandlungsverfahren bei älteren Patienten mit instabiler intraartikulärer distaler Radiusfraktur.
Abstract
A randomized, prospective study was carried out on 32 elderly patients with an unstable intra-articular distal radial fracture (AO-C2 or C3) to compare primary external fixation with plaster immobilization. The radiological outcome in the external fixator group was significant better than in the plasterimmobilization group. In particular, the radiocarpal angle and radial inclination were regained and maintained in the external fixator group. However, the functional results at six weeks, three months, and one year showed no statistically significant differences between the two groups. Only the mean volar flexion at one year was better in the external fixator group. There were three major complications, one persisting reflex symphatetic dystrophy and two Dupuytren contractures, all in the external fixator group. Although external fixation of unstable intra-articular distal radial fractures in elderly patients leads to favourable radiological endresults, external fixation may lead to significant complications; the functional endresults are not superior to those treated with plaster immobilization. The conclusion must be: plaster immobilization and external fixation are of equal merit as treatment modalities in elderly patients with an unstable intra-articular distal radial fracture.
