Abstract

Abstract:

BACKGROUND: Distal radius fractures are often accompanied by a fracture of the ulnar styloid process in clinical practice. For distal radius fractures with surgical indication, open reduction and internal fixation are generally performed. Treatment of ulnar styloid fracture has been controversial.

OBJECTIVE: To observe the effect of ulnar styloid fracture healing on the recovery of wrist joint function after internal fixation of distal radius fracture.

METHODS: Thirty-nine patients with distal radius fracture combined with ulnar styloid fracture in the Second Affiliated Hospital of Anhui Medical University from June 2016 to January 2019 were enrolled. There were 24 males and 15 females with the age from 23 to 67 years old. All patients were treated with distal radius locking plate fixation. The results of the follow-up review on anteroposterior radiograph were used to determine the healing of the distal radius fractures. According to the healing status of ulnar styloid at the last follow-up, the patients were divided into healing group (n=20) and non-healing group (n=19). The palmar tilt, ulnar inclination and radial height were compared between the two groups based on anteroposterior radiograph and that were compared to the healthy side. The wrist flexion and extension activities, forearm rotation range, and Gartlant-Werley wrist function scores were detected. The study was approved by the Ethics Committee of the Second Affiliated Hospital of Anhui Medical University.

RESULTS AND CONCLUSION: (1) There was one case of ulnar-sided wrist pain in the healing group and two cases in the non-healing group; the difference was not statistically significant between the two groups (P > 0.05). There was no significant difference in fracture healing time between the two groups (P > 0.05). (2) At the last follow-up, palmar tilt and ulnar inclination of the healing group and the non-healing group were smaller than that of the healthy side (P < 0.05). However, there was no significant difference in radial height between the healthy side and the affected side (P > 0.05). There was no significant difference in the above indicators between the two groups (P > 0.05). (3) At the last follow-up, the flexion and extension range of the wrist joint in the healing group and the non-healing group were smaller than that on the healthy side (P < 0.05). There was no significant difference in the forearm rotation range between the healthy side and the affected side (P > 0.05). There was no significant difference in the above indicators between the two groups (P > 0.05). (4) At the last follow-up, there was no significant difference in the Gartlant-Werley wrist function scores or the excellent and good rate between the two groups (P > 0.05). (5) The results show that the healing of ulnar styloid fracture may not affect the rehabilitation of wrist joint after distal radius fracture fixation. The ulnar styloid process fracture can only be treated conservatively.
