The associations between residual displacement and ONFH after femoral neck fracture (mean ± standard deviation)

Groups	Displacement of the deepest portion of the femoral head fovea (mm)	Displacement of the center of the femoral head (mm)	Rotational angle (°)
ONFH (n = 28)	10.92 ± 9.18	7.575 ± 5.69	20.11 ± 10.27
Non‐ONFH (n = 213)	8.86 ± 6.29	5.31 ± 4.05	14.19 ± 11.09
P	0.026	0.005	0.005

P < 0.05 was defined as indicating a statistically significant difference. ONFH, osteonecrosis of the femoral head.
