The effect of applied loading and duration on cancellous bone morphology in the distal rabbit femur

Group	Sample size (n)	Bone volume fraction (BV/TV)		Direct trabecular thickness (mm)		Direct trabecular separation (mm)
		Control (left)	Loaded (right)	Control (left)	Loaded (right)	Control (left)	Loaded (right)
2 week	10	0.329 (0.05)	0.333 (0.04)	0.109 (0.02)	0.110 (0.02)	0.225 (0.04)	0.221 (0.03)
4 week	10	0.260 (0.03)	0.320 (0.04)	0.101 (0.02)	0.111 (0.02)	0.287 (0.05)	0.241 (0.05)
8 week	8	0.263 (0.04)	0.327 (0.06)	0.097 (0.01)	0.111 (0.02)	0.283 (0.08)	0.240 (0.09)

All values are mean (SD). Loads were applied to the right femur for 2, 4, or 8 weeks at 1 MPa for 50 cycles per day.
