Are Routine Follow-up Radiographs Necessary for Extra-articular Scapula Body Fractures Managed Conservatively?

Abstract

Introduction: Extra-articular scapula body fractures have been shown to have good outcomes with nonsurgical management. What is not known is whether routine postinjury imaging of these fractures is necessary for monitoring healing and alignment. As the shift toward providing cost-effective healthcare continues, we sought to evaluate if routine postinjury imaging of these fractures resulted in any change in management while secondarily evaluating the imaging for fracture patterns at risk of displacement.

Methods: A retrospective review of all extra-articular scapula body fractures managed nonsurgically at our institution was performed from January 2013 to December 2017. We measured the glenopolar angle, lateral border offset, sagittal angulation, and translation on both injury CT scans and follow-up radiographs to evaluate if any displacement occurred. In fractures that displaced more than 10 mm or 10° in any measurement, we evaluated the fracture pattern to see if any particular pattern posed a risk for displacement. In addition, we evaluated the cost of imaging for all radiographs obtained in the follow-up period.

Results: A total of 139 patients with 147 extra-articular scapula body fractures were included in our analysis. No patient experienced a change in management based on postinjury radiographs. A total of 120 patients underwent postinjury imaging with a total of 204 radiographic series ordered, equating to $172,769.50 in radiograph expenses. Final radiographs were obtained at an average of 48.4 days postinjury, and overall, no significant difference was observed (P < 0.05) in any radiographic measurement when compared with the initial injury imaging; however, when looking at fractures that displaced, transverse fracture patterns of the scapula body represented a risk factor for displacement (relative risk = 6.5).

Discussion: Satisfactory outcomes have previously been demonstrated with nonsurgical management of scapula body fractures and for most of these injuries postinjury imaging may not be necessary or cost effective.

Level of evidence: Level IV.
