The original Fig. 2a contained a labelling error within the image.

Fig. 2
figure 1

A 75 year-old female with a 7 year history of bisphosphonate use. Only a single cortical beak (arrow) was seen on anteroposterior (AP) radiographs (a). In addition to showing the BP-AFF corresponding to the radiograph (dashed arrow), the AP tomosynthesis revealed another unsuspected BP-AFF line (arrowhead) more inferiorly not associated with cortical beaking (b). Thus, BP-AFF may exist in the total absence of any radiographic signs

Page 6, Fig. 2a

The arrow in the upper aspect of the original Figure 2a is erroneous and should not be present in the image. This was a transcription error in the final stages of submission.

Where it should have read as:

There should only be a single, solid arrow pointing to the cortical beak on the lateral femoral diaphysis in Fig. 2a.
