The Value of Intraoperative 3-Dimensional Fluoroscopy in the Treatment of Distal Radius Fractures: A Randomized Clinical Trial

Published:January 16, 2020DOI:https://doi.org/10.1016/j.jhsa.2019.11.006

      Purpose

      This study attempted to determine the clinical effectiveness of the intraoperative use of 3-dimensional fluoroscopy compared with conventional 2-dimensional fluoroscopy in patients with distal radius fractures.

      Methods

      We performed a multicenter randomized clinical trial in which 206 patients were randomized between the use of 3-dimensional fluoroscopy or not during operative treatment of the distal radius fracture. The primary outcome was the quality of fracture reduction and fixation assessed on a postoperative computed tomography scan with a dichotomous outcome: indication for revision, yes or no.

      Results

      There was no significant difference in whether the fracture required revision surgery: 31% (2-dimensional group) versus 24% (3-dimensional group). In 11% of distal radius fractures allocated to the 3-dimensional group, additional intraoperative corrections (screw replacements) were performed.

      Conclusions

      Compared with 2-dimensional fluoroscopy, the use of intraoperative 3-dimensional fluoroscopy does not appear to improve the quality of reduction and fixation in the management of patients with a distal radius fracture. However, the use of 3-dimensional fluoroscopy appears to have advantages such as more intraoperative revisions and less revision surgeries that this study could not clearly demonstrate.

      Type of study/level of evidence
