Clinical Impact of United Versus Nonunited Fractures of the Proximal Half of the Ulnar Styloid Following Volar Plate Fixation of the Distal Radius

Ulnar styloid process nonunion and outcome in patients with a distal radius fracture: A meta-analysis of comparative clinical trials

“…1). Eight studies met our inclusion criteria; however, two studies did not report sufficient data to be included in the meta-analysis leaving six studies available for meta-analysis [24][25][26][27][28][29][30]. These studies included a total of 135 patients in the union group and 230 in the nonunion group.…”

“…Raw data were available for three out of the six studies [26,29,30]. Six patients (three in the union group and three in the nonunion group) had participated in both the studies of Buijze and Wijffels; their data were included only once in our meta-analysis.…”

“…The combined raw data of the three studies [26,29,30] included the outcome data of 40 patients with union and 65 patients with nonunion of the USP. No statistically significant differences between the combined union and nonunion groups were found for patientreported outcomes, range of motion, grip strength, and pain (Table 3).…”

“…Mentzel and colleagues reported a better residual function if the USP fracture unites [24]. Others found that nonunion of the ulnar styloid did not affect functional outcome or pain following volar plate fixation of a DRF [25][26][27][28][29][30].…”

Effect of ulnar styloid fracture on outcomes after conservative treatment of distal radius fracture

“…[5] The data from the literature is contradictory as to whether USF results in instability, disability and pain in the wrist [6,7] or has no adverse effect. [2,3,8,9] The triangular fibrocartilage complex (TFCC) consists of ligament, structures that contribute to distal radioulnar joint (DRUJ) stability as well as ulnocarpal stability. [1,4,10] and the secondary attachment of these structures is the ulnar styloid.…”
