Relationship between the FNA and the ages of patients

Age group (years) n Normal hips (FNA;°) Dislocated hips (FNA;°)
(mean ± SD) (mean ± SD)
3–5 22 35.9 ± 9.1 42.7 ± 9.9
5–7 26 37.8 ± 8.3 48.4 ± 10.7
7–8 20 36.7 ± 9.5 51.6 ± 8.2

Normal hips: r = 0.568; P = 0.093. Dislocated hips: r = 0.672, P = 0.002
