Radiology of osteoporosis.

Bone densitometric studies have shown that osteoporosis is a result of prolonged, slow bone loss and that the pattern of loss is different for trabecular and cortical bone. Structurally-insufficient osteoporotic bone is predisposed to fractures. Among the clinically manifest osteoporotic fractures, distal radius leads the list, followed by hip, spine, and proximal humerus. This article examines the use of conventional radiography as well as other imaging-based modalities for the evaluation of osteoporosis and associated fractures in the axial and appendicular skeleton.
