Discontinuation of denosumab in postmenopausal osteoporosis causes a rebound phenomenon with a rapid increase in bone turnover markers and accelerated bone loss, often within 6-12 months. Without an appropriate relay therapy, up-to 10% of the patients experience multiple vertebral fractures. This phenomenon is linked to a multifactorial dysregulation of bone remodelling. In 2021, the European Calcified Tissue Society (ECTS) proposed guidelines for discontinuing denosumab in patients with postmenopausal osteoporosis. Our review covers the latest research on risk stratification for rebound phenomenon, the various relay treatment options based on risk levels, and the recommended follow-up for these patients. Post-denosumab treatment is important. Bisphosphonates therapy and regular monitoring of serum CTX (crosslaps) represent the cornerstone of the management of rebound phenomenon following denosumab discontinuation in postmenopausal osteoporosis.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
