General Pattern of Bone Development Over Time

The black line represents the general pattern of bone mass accrual and loss over the three phases of bone development: (I) growth, (II) modeling or consolidation, and (III) remodeling. The T-score, which measures bone mineral density (BMD) by DEXA, is used as a clinical proxy for bone mass. WHO cutoffs for osteopenia and osteoporosis are indicated.
