Abstract

Introduction: Restoration of normal anatomic alignment is a key component of the treatment of distal radius fractures (DRF). This study aimed to evaluate the accuracy of ultrasonography (US) in determining the adequacy of closed reduction in these fractures.

Methods: DRF patients admitted to the emergency department of Al-Zahra Hospital, Isfahan, Iran from September 2011 to 2012, were enrolled. After closed reduction, the adequacy was investigated through both US and control plain radiography. Then, sensitivity, specificity, positive and negative predicative values of US in confirmation of closed reduction was evaluated. In addition, inter-rater agreement between the two diagnostic tools was analyzed by calculating Cohen's kappa coefficient.

Results: Finally, 154 patients were evaluated (females: 53.9%) with mean age of 40.03±14.7 (range: 22-73). US had sensitivity, specificity, positive and negative predictive value of 99.3% (95%CI: 96.2-99.9), 100.0% (95%CI: 62.9-100.0), 100.0% (95%CI: 97.5-100.0), and 88.9% (95%CI: 51.7-98.1) in confirmation of the adequate reduction, respectively. In addition, inter-rater reliability was 0.94 (95%CI: 0.89-0.99; p<0.0001).

Conclusion: It seems that US could be considered as a highly sensitive, accurate, easy to use, noninvasive and safe tool for guidance and confirmation of closed reduction in DRF.
