No need for any data protection stuff, and probably no need for any pitchforks. Just get an appointment with the consultant orthopod that you are under and ask to be shown the X-ray, then ask if it’s obvious, and if so, why it wasn’t spotted.
You might get an apology if it was staring someone in the face, but it’s more than likely that it didn’t really show up.
Project; the NHS are committed to data security in a very big way, and looking at any patient info that you are not entitled to, even your own, is a serious breach of policy which is dealt with using a big HR hammer.
