Abstract

Purpose
This study examined the demographic and radiological risk factors for later reduction loss of distal radius fractures treated conservatively.
Materials and Methods
This study enrolled patients treated for distal radius fractures between January 2017 and December 2019. Seventy-eight patients were included in the analysis and divided into two groups. The patients who showed minimal reduction loss within an acceptable radiologic angle after initial manual reduction were classified as Group A. The patients who showed reduction loss out of an acceptable radiologic angle and finally malunited or converted to surgical treatments were classified as Group B. The patient’s age and bone marrow density were used as demographic data. The initial X-ray images were evaluated to determine the fracture type. Various radiological parameters were measured.
Results
The 78-patient study cohort consisted of nine men and 69 women with a mean age of 67 years. Forty-eight cases were sorted into Group A, and 30 cases into Group B. On logistic regression analysis, the age of 80 or older was a risk factor for later fracture displacement among the demographic factors (p=0.037, odds ratio=4.937). Among the radiographic factors, the presence of distal ulnar fracture and dorsal cortical comminution were disclosed as risk factors of later displacement (p=0.049, 0.003, odds ratio=3.429, 7.196).
Conclusion
When conservative management for distal radius fracture is decided in patients more than 80 years of age or accompanied by a distal ulnar fracture or with dorsal cortical comminution, the possibility of later displacement of the distal radius should be considered.
