RESUMEN
some studies shown that position of fetus in uterus could be some lower limb deformities. Up to now, no research has been done about relationship between type of delivery and tibiofemoral developing. We were investigated to consider of this relationship in people between 3-16 years old in Ahvaz city. This cross-sectional study was carried out on 853 people [455 girls and 398 boys]. Tibiofemoral [TF] angle, Intercondylar and intermalleolar distances were measured in standing position with knees and hip in full extension. Information about a kind of delivery [caesarian or vaginal] were taken by questionnaires in which was completed by their parents. TF angle in cesarean sections was more than in vaginal deliveries and the difference was statistically significant [p=0.02]. Intercondylar and intermalleolar distances in cesarean sections were more than in vaginal deliveries but the differences were not statistically significant. There is significant relationship between tibiofemoral and type of delivery, but for the future work need to evaluate the effect of fetal position and adaptathions [mechanism of laber] in the development of tibiofemoral angle after birth
RESUMEN
In evaluation of genu varum and genu valgum which are common in growth period of children, tibiofemoral [TF], intercondylar [1C] and intermaleolar [IM] distances are commonly measured. Normally, the legs of most newborns are slightly curved or have moderate curves medially when they are in standing position. During their growth, the extension of the lower limb changes. The aim of this study was to determine the relationship between normal intercondylar and intermaleoar distances and physiolgical factors among these subject groups. In this cross-sectional study a group of 850 children [452 females, 398 males] aged between 3 to 16 years old were studied. The samples were collected randomly from kindergartens, preschool care centers and schools in all 4 districts of Ahvaz, plus a few patients in Shafa hospital. The intercondylar and intermaleolar distance were examined in standing position, while the knee and hip joints were fully extended and the two medial maleolus or two medial condye of knees were in contact. In this study, descriptive statistics as well as t- and ANOVA tests were used for comparison. Pearson correlation for the survey were used data analysis by SPSS version 15. The mean of intercondylar distance among studied groups was 1.65 +/- 0.86: 1.5 in boys and 1.71 cm in girls respectively. The mean of intermaleolar distances was 2.31cm in males 2.05cm and in females 2.53 cm, the difference was significant [P<0.05]. There was a direct ralationship between intermaleolar distance and weight, height and length of leg, but relationship between Intercondylar distance and these factors is in reverse order
