Purpose: The purpose of this study was to examine the influence of radial overgrowth after surgical treatment for pediatric distal radius fractures.
Materials and Methods: Twenty-two pediatric patients under the age of 10 years who underwent surgical treatment for a distal radius fracture without physeal injury were enrolled in this study. They were divided into 2 groups according to the ulnar fracture; distal radius alone fracture in 9 patients group and radioulnar both fracture in 13 patients group. The radial length, ulnar variance, and radial inclination at the last follow-up X-ray were measured using a simple lateral radiograph. The visual analogue scale (VAS) of distal radioulnar joint pain, the Mayo wrist score, and range of motion of the wrist were assessed for the clinical results.
Results: At mean follow-up period of 3.7 years, radial overgrowth was 2.2 mm (p=0.01) compared with the un-injured side. There was negative ulnar variance on the injured side, an average of 0.8 mm (p=0.01). Clinically, mean VAS was 0.2, and the Mayo wrist score was 99.3. No significant difference in radial overgrowth (p=0.32), ulnar variance (p=0.99), VAS (p=0.29), and the Mayo wrist score (p=0.34) was observed between groups.
Conclusion: Radial overgrowth and negative ulnar variance was observed after surgical treatment of pediatric distal radius fracture without physeal injury. However, the radial overgrowth does not affect clinical outcomes.
