“…The presence of rheumatoid arthritis was shown to increase fracture probability independently of BMD and glucocorticoid intake [21]. Other forms of secondary osteoporosis, such as hypogonadism or premature menopause (<45 years) [22][23][24], inflammatory bowel diseases [25][26][27][28], immobilisation due to spinal cord injury [29] and thyroid disorders [30], are generally associated with increased fracture probability; however, whether these are independent of BMD remains controversial. Therefore, for FRAX® modelling purposes, other causes of secondary osteoporosis were attributed the same level of risk as rheumatoid arthritis in the absence of a BMD value and no additional risk if a BMD value was available.…”
