Analysis of Proximal Femoral Parameters in Adolescent Idiopathic Scoliosis

Table 4

Bilateral asymmetry. The presence of differences between patients limb sides are presented here with individuals divided into three groups based on the magnitude of difference between the two sides, irrespective of side.

Parameter / differences	Under 3 mm/degree (n=)	Between 3 and 5 mm/degree (n=)	More than 5 mm/degree (n=)
Femoral head diameter	319	1	0
Femoral offset	266	23	31
Neck length	274	20	26
Neck shaft angle	252	39	29
FM-FS	318	2	0
Femoral torsion	206	22	92
