Glucocorticoid (GC) treatment is associated with a 50-60% increase in the r
isk of hip fracture and a 2-3 fold increase in the risk of vertebral fractu
res in adults. Bone loss occurs early in GC treatment, and although some re
covery of bone mass occurs with time, complete recovery is unlikely. Patien
ts who already have low bone mass are the group that are most susceptible t
o fracture. Fracture rates are highest in postmenopausal women, especially
those who are not receiving hormone replacement therapy, but are also incre
ased in men and premenopausal women. Therapies are now available to prevent
GC-induced bone loss and should be employed early in GC treatment.
