Table 1.

Radiographic versus in vivo determined cup coverage.

	Radiographic cup coverage (%)	In vivo cup coverage (%)	Δ cup coverage (%)	P value (P1)

All patients (n=20)	84.27 (3.63)	91.20 (3.50)	6.93 (2.47)	<0.001
High hip center(n=8)	81.42 (2.62)	88.99 (3.59)	7.57 (1.18)	<0.001
Normal hip center (n=12)	86.17 (2.92)	92.67 (2.67)	6.50 (3.02)	<0.001
P value (P2)	0.002	0.017	0.357

Δ cup coverage (%)=in vivo cup coverage–radiographic cup coverage; P1: Comparing radiographic and in vivo cup coverage; P2: Comparing high and normal hip center groups.

Means (standard deviations) are provided above for cup coverage.
