Figure 3.

Peripheral quantitative computed tomography (pQCT) scans of one representative mouse in each group. Trabecular bone mineral density (BMD) was determined with a metaphyseal scan at a point 3% of the length of the femur from the growth plate and the inner 45% of the area was defined as the trabecular bone compartment. (a) Sham-operated control; (b) ovariectomy control; (c) sham-operated, arthritic mouse; (d) ovariectomized, arthritic mouse. The bar shows the density of the bone, from 0 (black) to 750 mg/cm³ (white).
