Bone quality assessment for total hip arthroplasty with intraoperative trabecular torque measurements

Table 3 The correlations ( p <0.05) between the values of the torque measurement, the bone mineral density, the compressive strength, and the other detected and analyzed parameters

Parameter	BMD (DXA)	BMD (μCT)	BV/TV	Tb.Th	Tb.N	Tb.Sp	Compressive strength
Torque head	0.86	0.80	0.82	0.63	0.80	−0.77	0.85
BMD (μCT)	0.83	-	1.0	0.85	0.94	−0.91	0.79
BMD (DXA)	-	0.83	0.82	0.82	0.69	−0.67	0.80
Torque neck	0.91	-	-	-	-	-	-

Pearson′s product–moment was used for correlation.
