Modern digital radiological techniques include “stitching” together multiple x-ray images. This provides one overall image of the area of interest, such as the entire spine or lower limbs, for deformity assessment. Dedicated software automatically combines separate exposures and allows for overlap. Image acquisition is rapid, minimising patient motion artefact and reducing distortion.1 However, if images are inappropriately put together (digitally stitched), stitching errors may occur with this computer-driven process. If not manually corrected by the radiology technician, the supplied image may hide pathology or give the false impression of abnormality. Four cases of digital stitching error have recently occurred in our tertiary referral paediatric hospital.
