Herniographic examinations were performed on more than 4,000 patients. The method was found to be of great value in patients with obscure symptoms in the groin or pelvis. Herniography shows not only hernial sacs but also the general condition and tissue strength of the inguinal part of the abdominal wall. The different types of hernias have different signs that, as a rule, allow an exact diagnosis. The pelvic floor and the pouch of Douglas can always be evaluated. Young athletes with severe symptoms in the groin, in most instances, were found to have some type of hernial rupture and often osteochondritis in the pubic symphysis as well. In women, the clinical diagnosis of hernia is often difficult. Herniography was of great value in these patients.
