The role of pelvic bone anatomy in the pathogenesis of inguinal hernia.

BACKGROUND a small number of reports have suggested that inpatients with inguinal hernia, certain pelvic anatomical traits prevail, which are characterized by the low position of the groin, resulting in a marked verticality of the inguinal fold.Based on this notion we investigated a possible correlation of this anatomical characteristic with hernia development, by applying a simple clinical research protocol. METHODS two groups were formed. A study group including 25 adult patients with a history of inguinal hernia or aclinically proven inguinal hernia and a control group of 10 individuals of the same age and sex distribution with the study group, but with no history of inguinal hernia. On anteroposteriorpelvic plain x-rays, we measured Radoievitch'€™s angle which is formed by the interspinal line and the line passing from the anterior superior iliac spine and the pubic tubercle.Mean values of Radoievitch'€™s angle were then compared between the two groups. RESULTS patients with inguinal hernia had greater values concerning Radoievitchâ€'s angle in a statistically significant manner when compared to controls (p=0.004). CONCLUSIONS individual variability in the configuration of the adult bony pelvis is an important factor in the development of inguinal hernia. Pelvimetry could affect the choice of hernia repair and radiological pelvimetry could be included in the preoperative planning of hernia repair.
