Neurological examination is unremarkable. X-ray of the spine reveals a compression fracture of a thoracic vertebra.

its a uworld question. the patient suffers from osteoporosis (old age, female, compression fracture). and Uworld says that in osteporosis the calcium and PTH relationship remains normal and so the answer is C.

thoracic vertebrae is a weird place for osteoporosis to be though, no?
