The Value of Routine Radiography in the Nonoperative Treatment of Metatarsal Fractures: A Retrospective Cohort Study

Abstract

Although widely used in follow-up treatment protocols, the added value of routine radiographs to clinical decision-making in nonoperative treatment of patients with metatarsal fractures is unclear. This retrospective cohort study aimed to determine whether routine follow-up radiographs contributed to changes in treatment strategies in nonoperative treatment of patients with a metatarsal fracture. Adult (aged ≥ 18 years) patients who received nonoperative follow-up treatment for a metatarsal fracture between May first, 2020 and May second, 2022 were included. All relevant data were extracted from patient records. Radiographs without a documented clinical indication were classified as routine. Outcomes included changes in treatment strategies based on routine radiographs during follow-up treatment and secondarily, changes in treatment strategy based on clinically indicated radiographs. A total of 168 patients were included, with 135 single and 33 multiple metatarsal fractures. During follow-up, 223 radiographs were performed, of which 154 (69%) were routine and 69 (31%) were on clinical indication. Of routine radiographs, 9 (6%) led to a change in treatment which only included additional imaging. No switch to operative treatment or prolonging of immobilization was observed based on routine radiographs. Of clinically indicated radiographs, 16 (23%) led to a change of treatment, including prolonged immobilization (n = 2), additional follow-up appointments (n = 1) and additional imaging (n = 12). Our results show routinely performed radiographs seldom affect treatment strategies in nonoperative treatment of metatarsal fractures, indicating minimal added value to clinical decision-making. Omitting routine radiographs from treatment protocols may contribute to the reduction of unnecessary healthcare resource utilization in clinical practice.
