Ct.A = cortical area; Ct.Th = cortical thickness; EC = endocortical circumference; PC = periosteal circumference; Ct.vBMD = cortical volumetric bone mineral density; Ct.Po = cortical porosity; BV/TV = bone volume/total volume; Tb.A = trabecular area; Tb.N = trabecular number; Tb.Th = trabecular thickness; Tb.Sp = trabecular separation.

Values are presented as mean ±SE adjusted for bone age. Significant p values are in bold.

a

p = controls versus mild-trauma patients, using the Dunnett adjustment for multiple comparisons.

b

p = controls versus moderate-trauma patients, using the Dunnett adjustment for multiple comparisons.

c

p = controls versus all patients.
