Abstract

Abstract: BACKGROUND: In recent years, the effect of reduction and fixation of medial ulnar dorsal fracture block on the recovery of wrist function after operation has attracted more attention from clinicians.
OBJECTIVE: To compare the clinical effect of different fixation methods for distal radius fractures.
METHODS: From August 2018 to June 2019, 53 patients with closed distal radius fractures were selected from the Department of Orthopedics, the Third Affiliated Hospital of Anhui Medical University (with ulnar dorsal fracture block). Of these, 23 were men, and 30 were women. The A group (n=22) was treated with palmar approach, while B group (n=31) was treated with metacarpal plate combined with dorsal closed reduction ulnar dorsal fracture block. The carpal radiographs were taken to observe the changes of distal palmar inclination angle, ulnar deviation angle, radius height and displacement of ulnar dorsal fracture block. The functional recovery of carpal joint was evaluated by Gartland-Werley wrist function scoring system, and the irritation and injury of extensor tendon around wrist joint were observed. This study was approved by the Ethics Committee of Anhui Medical University.
RESULTS AND CONCLUSION: (1) Totally 53 patients received 10-14 months of follow-up, without incision infection or obvious vascular and nerve injury. (2) At 2 days after operation and the last follow-up, there was no significant difference in palmar inclination angle, ulnar deviation angle, and radius height between the two groups (P > 0.05). (3) Gartland-Werley wrist function score showed that there was no significant difference in the excellent and good rate of wrist function between the two groups at the last follow-up (P > 0.05). (4) A group had lower incidence of late displacement of distal ulnar dorsal fracture block than B group (P < 0.05), and there was no significant difference in the incidence of wrist extensor tendon irritation or injury between the two groups (P > 0.05). (5) The results showed that both palmar approach plate-assisted dorsal approach and palmar approach plate combined with dorsal closed reduction and fixation can achieve satisfactory results in the treatment of ulnar dorsal fracture block of distal radius fracture. However, the metacarpal approach plate assisted with the fixation of the dorsal approach can effectively prevent the displacement of the fracture block of the dorsal ulnar side.
