is the one that protrudes through lumbar triangle
. This triangle lies in the posterolateral abdominal wall bounded in front by free margin of external oblique muscle
, behind by latissimus dorsi
and below by iliac crest
. The neck (place where a hernia protrudes into the opening) is large, so chances of strangulating
are small. Occurs more often in males on the left side. Protrudes when the child cries.
