O3044 EXTERNAL FIXATION IN COLLES’ FRACTURE: RESULTS AND COMPLICATIONS. A RETROSPECTIVE STUDY

Abstract

Aims: The aim of this study was to evaluate the use of external þxation in Collesñ fracture.Methods: The history of all patients with distal forearm fracture (n=257) treated in Kuopio University Hospital during the year 1992 were studied. Radiographs of patients over 15 years of age treated with external þxation were studied (n=31), but only Collesñ fractures with dorsal angle (n=20) were cross-examined with a control group of conservatively treated randomly selected patients with a similar fracture (n=17). Radial shortening, dorsal angle and radial inclination were measured from the radiographs. Results: 70% and 22% of the fractures were intra-articular in external þxation (EF) and control (C) groups, respectively. The studied parameters at baseline were only a little bit (NS) worse in the EF group than in the control group. After reduction, the loss of radial length and inclination were corrected signiþcantly better using EF than in conservative treatment group. However, only radial inclination was maintained signiþcantly better in EF group after the immobilisation period (5–7 wk). There were less complications and functional problems reported in the conservatively treated patients (8% of all cases) than in the patients treated with external þxation (23%). However, worsening in the anatomical reduction during conservative treatment was reported in 22–27% of all cases. Conclusions: Only loss of radial length and inclination can be reduced signiþcantly better with external þxation than using conservative treatment. There seems to be no reason to use external þxation to reduce dorsal angle only. External þxation leads more often to complications than conservative treatment.
