Comparison of Valgus Correction Angle between Patients with Developmental Dysplasia Hip and Normal Volunteers Measured by Three-Dimensional Reconstruction and X-Ray

Table 2

The VCA of DDH group and normal group.

Group	Method	VCA		Range (°)
DDH	3D	Upper	100	2.98-7.83
DDH	3D	Lower	100	0.83-11.48
DDH	X-ray	Upper	100	0.98-6.89
DDH	X-ray	Lower	100	-4.34-11.39
Normal	3D	Upper	112	3.42-7.00
Normal	3D	Lower	112	2.50-7.45
Normal	X-ray	Upper	112	2.91-6.87
Normal	X-ray	Lower	112	0.36-6.37

VCA: valgus correction angle; DDH: developmental dysplasia of the hip.
