Comparison in regression of femoral neck anteversion in children with normal, intoeing and outtoeing gait--prospective study.
We studied the 950 children for spontaneous regression of femoral neck anteversion (FNA) angle. The children were divided in three groups. The first group comprised children with normal gait, second group comprised children with intoeing gait and the third group children with outtoeing gait. All children were seen first time at age seven. Second examination was performed at age 10 and the third at age 14. The FNA was measured using ultrasound techniques. The mean FNA angle in the first group was 24 degrees, and decreased during examined period for average 1 degree per year. The FNA angle in the second group was on average 42 degrees at age 7 and decreased average 1.6 degrees per year. FNA angle in group of children with outtoeing gait was average 13 degrees and did not significantly change during all three examinations. We found that medial and lateral rotation in the extended hip correlate with FNA angle as well as differences between medical and lateral rotation. On the third examination percentage of children with intoeing gait decreased from 12.8% to 1%, while number of children with outtoeing gait did not change significantly during examined period.
