Influence of Ulnar Styloid Fracture Types on the Treatment of Distal Radius Fractures

Abstract

Objective: To analyze the effect of ulnar styloid process fracture types on the treatment of distal radius fracture. Methods: A total of 49 patients with distal radius fractures admitted to the hospital between December 1, 2018 and November 30, 2022 were selected. Among the patients, 26 of them were complicated with type I ulnar styloid fracture (the first group), and 23 patients were complicated with type II ulnar styloid fracture (the second group), and were treated with open reduction and internal fixation using Kirschner wire and tension band. The total effective rate, anatomical indicators such as palm inclination and ulnar deviation, and the range of motion of the wrist joint were compared between the two groups. Results: The total effective rate of the first group was higher than that of the second group (P < 0.05). There was no difference in anatomical indicators between the groups before operation and 3 months after operation (P > 0.05). Before operation, there was no difference in the range of motion of the wrist joint between the groups (P > 0.05). 3 months after operation, the range of motion of the wrist joint in the first group was greater than that in the second group (P < 0.05). Conclusion: The types of ulna styloid fracture can affect the effectiveness of treatment and joint mobility of distal radius fracture.
