Purpose: The purpose of this study was to determine the relationship between dorsal metaphyseal comminution and the radiographic and functional outcomes of patients with distal radius fractures treated by closed reduction and cast immobilization.
Methods: Twenty-six patients with acute distal radius fractures were retrospectively reviewed. The mean age of this patient group was 62.8 years (range, 45-87 years). Eighteeen cases were AO type-A3 and 8 were AO type A2. Radiographic and functional parameters were analyzed and compared between the patients who presented with or without dorsal metaphyseal comminution on their initial radiographs in order to assess the clinical outcomes. The radiographic parameters included radial inclination, radial length, volar/dorsal tilt, and ulnar variance. In order to measure the functional outcomes, each patient’s range of motion, grip strength, Quick disabilities of the arm, shoulder, and hand (DSAH), visual analog scale (VAS), and Mayo score were determined.
Results: Seventeen patients (65%) presented with dorsal metaphyseal comminution on the initial radiographs. Radial inclination, radial length, and volar/dorsal tilt were decreased and ulnar variance was increased on the final radiographs in comparison with the postreduction. However, there were no statistically significant differences between the two groups that presented with or without dorsal metaphyseal comminution (p>0.05). None of the functional parameters (i.e., range of motion, grip strength, DASH, Mayo, and VAS score) were significantly different between the two groups (p>0.05).
Conclusion: Dorsal metaphyseal comminution seems to have no significant impact on radiographic and functional outcomes when closed reduction and cast immobilization was planned for the treatment of distal radius fracture.
