Measurements of femurs according to classification of Hartofilakidis et al.*

Parameter	C1 Mean ± SD (mm)	C2 Mean ± SD (mm)	p Value
Height of dislocation (mm)	42.9 ± 12.0	62.0 ± 17.1	< 0.001
Femoral height (mm)	46.0 ± 8.9	45.2 ± 8.8	0.746
Height of greater trochanter (mm)	50.4 ± 6.9	58.3 ± 5.1	< 0.001
Discrepancy between height of greater trochanter and femoral head center* (mm)	5.0 ± 12.0	13.2 ± 11.3	0.020

* Types C1 and C2 hips (AP view).

Values are expressed as mean ± SD; *the value is positive when the tip of the greater trochanter is higher than the femoral head center.
