The right femurs were subjected to the μ-CT scanning as previously described [36 (link),37 (link)]. Briefly, the right femur was scanned and captured by the Quantum GX μCT instrument (PerkinElmer, Waltham, MA, USA). The parameters in the volume of interest were analyzed by the Analyzer Software (V12.0), including (1) BMD (bone mineral density); (2) BV/TV (bone volume fraction); (3) BS/TV (bone surface density); (4) Tb.N (trabecular number); (5) Tb.Sp (trabecular separation); (6) Tb.Th (trabecular thickness); (7) Conn.D (connectivity density); and (8) SMI (Structure Model Index).
