A 68-year-old woman has come to her physician’s office with onset of back pain that began when she was turning over in bed two days ago. It is most severe between her shoulder blades and is aggravated by movement, especially bending forward; although any movement above the waist seems to aggravate it somewhat. She is unable to stand completely upright. The pain has responded a bit to OTC (over the counter) pain medication she takes for her arthritis, but it is still quite severe and does not appear to be improving at all.

The patient states that her arthritis medication does not appear to be as effective as it used to be and she has had to cut back on many of her activities. The physician notes on checking her record that she has been a smoker since her teenage years and she has gradually been losing height at each of…
