Do Routine Postoperative Radiographs Influence the Management of Distal Radius Fractures Following Volar Locking Plate Fixation?

BACKGROUND

Distal radius fractures (DRFs) are a common orthopaedic injury, often requiring surgical intervention. Routine postoperative radiographs are frequently obtained after surgical fixation to ensure adequacy of fixation and rule out early complications, yet their necessity remains unclear. Through this study, we tried to evaluate the impact of routine postoperative radiographs on the management of DRFs. The objective was to determine whether routine postoperative radiographs are necessary for the effective management of patients following surgical fixation of DRFs using volar locking plates.

METHODS

A review of 176 patients who underwent distal radius open reduction and internal fixation with volar locking plates at a UK district general hospital was conducted over a period of two years. Data on patient demographics, fracture characteristics, postoperative imaging new findings, and management changes were collected and analysed. The primary outcome measure was the rate of reoperation based on new findings in the routine postoperative radiographs.

RESULTS

Routine postoperative radiographs were obtained in all the cases, with only 1% (one patient) requiring reoperation based on the presence of new findings on the postoperative radiographs. Approximately 8% (12 patients) experienced a change in their management in the form of prolonged cast immobilization.

CONCLUSION

Routine postoperative radiographs for DRFs with open reduction internal fixation may have limited impact on management decisions. The study highlights the potential overutilization of postoperative radiographs, leading to increased healthcare costs and radiation exposure. Based on the study's findings, a case-by-case approach, considering fracture type, associated injuries, and clinical indications, is advocated. Reducing the use of routine radiographs could save resources and reduce unnecessary radiation exposure without compromising patient care.
