F. Miller et al., MEASURING ANTEVERSION AND FEMORAL NECK-SHAFT ANGLE IN CEREBRAL-PALSY, Developmental Medicine and Child Neurology, 39(2), 1997, pp. 113-118
Femoral anteversion was measured by computed tomography (CT) in 40 chi
ldren with cerebral palsy, however an accurate measurement was possibl
e in only 59 of the 80 hips. Flat-surface measurement of anteversion w
as possible in ra of 80 hips by CT, and in 36 of 40 hips by ultrasound
. A high neck-shaft angle correlated with an inability to measure ante
version by CT. Measuring by ultrasound allowed subjects to be position
ed in internal rotation and in this way accurate measurements of neck-
shaft angles were obtained.
