Aberrant formation of the decussations of the linea alba, leading to a midline pattern of single anterior and posterior lines, predisposes to the formation of epigastric hernias (epiploceles). Internal supravesical hernias probably arise from a congenital fascial deficiency. Perihernial fasciae or muscles may be malformed in lumbar hernias. Interparietal hernias are often a product of ectopic testicular descent. Multiparity and age produce laxity of the pelvic floor to cause perineal hernias.
