Umbilical cord insertion: normal location in neonates.
The distances between the xyphoid appendix and the insertion point of the umbilical cord (XU) and between the xyphoid appendix and upper edge of the pubic symphysis (XP) were measured in 201 newborn infants. The mean ratio XU/XP was 0.62 (S.D. 0.044) with no differences between sexes nor correlations with weight or length. Ratios lying between 0.53 and 0.71 can be considered as within the normal range.
