Introduction
In medicine, we commonly use simple English letters or abbreviations to denote the fetal position and orientation. Specifically, “L” stands for left, “O” for occiput, and “A” for anterior. Thus, “LOA” indicates occiput-left-anterior—meaning the fetal occiput is positioned in the left anterior quadrant of the maternal pelvis.

In medicine, we commonly use simple English letters or abbreviations to denote the fetal position and orientation. For example, in a cephalic presentation, the fetal position is determined by the relationship between the fetal occiput and the maternal pelvis. Here, “L” stands for left, “O” for occiput, and “A” for anterior; thus, “LOA” denotes occiput-left-anterior—meaning the fetal occiput lies in the left anterior quadrant of the maternal pelvis.
