Objective This study was performed to determine the prevalence of triangular fibrocartilage complex (TFCC) injuries as shown by 3.0T magnetic resonance imaging (MRI) in patients with distal radius fractures. Methods In total, 57 patients with distal radius fractures underwent 3.0T MRI examinations to observe the incidence of TFCC injuries after manual reduction and cast fixation. The fracture type was categorized by the AO classification, and the TFCC injury pattern was evaluated using the Palmer classification. The correlation between the location of the TFCC injury and the distal radius fracture pattern, distal radioulnar joint instability, or ulnar styloid fracture was analyzed. Results Fifty-five TFCC injuries were diagnosed. There was no significant relationship between the TFCC injury pattern and the type of distal radius fracture, distal radioulnar joint instability, or ulnar styloid fracture. Conclusions This study revealed a high prevalence of TFCC injuries in patients with distal radius fractures. The 3.0T MRI examination helps to assess TFCC injuries in patients with distal radius fractures. Clinical Trial Registration ChiCTR1800017101.

Wrist Function

Four patients with dorsal dislocation of the distal radioulnar joint and ulnar styloid malunion had corrective osteotomy of the ulnar styloid. Dislocation of the distal radioulnar joint was reduced in three of four patients. Subluxation persisted in the remaining patient. Wrist function improved in all patients. These results support the contention that a displaced ulnar styloid fracture with distal radioulnar joint dislocation should be reduced and internally fixed. Corrective osteotomy is recommended for malunion of the ulnar styloid associated with dislocation of the distal radioulnar joint.

Distal Radioulnar Joint Subluxation

In 55 patients with ulnar styloid fractures, the site and displacement of the fracture was examined in relation to distal radioulnar joint subluxation/dislocation by computed tomography (CT). Distal radioulnar joint subluxation/dislocation confirmed with CT in 18 of 55 patients, irrespective of the site of the ulnar styloid fracture. In 21 patients with nondisplaced styloid fractures, only 3 fractures were associated with distal radioulnar joint subluxation/dislocation. In 34 patients where the styloid fracture was displaced for 3 mm or more, 15 fractures were associated with a distal radioulnar joint subluxation/dislocation. Therefore, ulnar styloid displacement of 3 mm or more suggests the need for further examination of the distal radioulnar joint.

This study investigates the question of whether open repair of acute distal radioulnar joint instability at the time of volar plating of distal radius fractures would enable early mobilization of the wrist without the risk of distal radioulnar joint instability. We evaluated 29 patients of mean age 53 years with a distal radius fracture and acute distal radioulnar joint instability who underwent volar plating of the radius combined with surgical repair of the triangular fibrocartilage complex or an ulnar styloid base fracture, followed by active motion exercise of the wrist at 1 week after surgery. At 1 year after treatment, all patients had a stable distal radioulnar joint and grip strength averaged 90% of the normal side. This study demonstrates that surgical repair of the triangular fibrocartilage complex or ulnar styloid fracture followed by early mobilization did not result in distal radioulnar joint instability, and suggests that the surgical treatment of distal radioulnar joint instability may permit early mobilization of the wrist in patients who are considered suitable for rapid rehabilitation after surgery. Type of study: Therapeutic Level IV
