Factors Predicting Late Collapse of Distal Radius Fractures Factors Predicting Late Collapse of Distal Radius Fractures

Abstract

Background: Although fractures of the distal radius are a common clinical presentation, many factors affect instability of these injuries. The aim of this study was to assess the influence of age, sex, distal radial ulnar joint injury (DRUJ), ulnar styloid fracture, and dorsal displacement in late collapse of distal radius fractures. Methods: Three hundred twenty-nine patient fractures were measured for dorsal tilt, radial inclination and ulnar variance after reduction and 2 months later. Reduction loss was analysed statistically against variables like DRUJ involvement, ulnar styloid fractures, age, sex, and AO classification. Results: After two months there was loss of reduction in 171(51.9%) cases. Loss of reduction was related to age, AO classification, involvement of DRUJ, ulnar styloid fractures and initial displacement. Conclusions: Factors such as age, associated DRUJ injury, ulnar styloid fracture are predictive of loss of reduction. Knowing these predictor factors, can aid in decision regarding treatment methods.
