OBJECTIVE: To explore the safety and efficacy of the single-operator controllable reduction device for distal radius fractures in clinical application.
METHODS: A retrospective analysis was conducted on 21 patients with extension-type distal radius fractures admitted from September 2023 to September 2024, including 6 males and 15 females. Their ages ranged from 26 to 84 years old, with a mean age of (62.09±13.43) years old. All patients received reduction and fixation treatment using the single-operator reduction device. The differences in distal radioulnar variance, ulnar inclination angle and palmar tilt angle of patients were compared before and after reduction. All measurements were performed by two independent physicians, and the average values were adopted. Twelve weeks after conservative treatment, wrist joint function was evaluated using the Cooney wrist scoring system.
RESULTS: All patients achieved clinical fracture healing and were followed up for more than 12 weeks. Before reduction, the distal radioulnar variance was (3.071±2.719) mm, ulnar inclination angle was (19.048±5.133)°, and palmar tilt angle was (-18.333±12.220)°. After reduction, the above indicators were (1.252±2.540) mm, (21.476±3.907)° and (5.714±7.478)° respectively. There were statistically significant differences in all indexes before and after reduction (P<0.05). At 12 weeks after reduction, the mean Cooney wrist joint functional score was (89.04±4.85) points, including 12 cases with excellent results, 6 good cases and 3 fair cases.
CONCLUSION: The single-operator controlled reduction device provides reliable radiographic restoration for Colles-type distal radius fractures, with favorable short-term functional recovery outcomes.
