Radiographs are typically the first line of defense when it comes to imaging.
Oftentimes, radiographs show no bony involvement, leading patients to believe nothing is wrong. This isnāt necessarily the case with bone stress injuries, as we know, early bony issues are missed and may not show up until later weeks.
A 2023 study reports up to 85% of radiographs at symptom onset are negative. Yet repeat radiographs a few weeks later may show new bone formation, indicating healing and confirming the diagnosis.
Further, athletes may decrease activity if they feel pain, leading to some healing before imaging and, therefore, not being visualized on imaging.
Evidence of bony injury may be seen within 2-8 weeks of symptoms. Early radiographs may have as low as 10% accuracy in correctly identifying a BSI. This increases to 30% to 70% in later weeks.
A negative radiograph, therefore, cannot necessarily rule out Bony injury.
