The incidence of inguinal hernias in children is as high as 4.5%. Indirect hernias usually present during the first year of life, but they may not appear until middle or old age. Indirect hernias are more common in premature infants than in term infants; they develop in 13% of infants born before 32 weeks’ gestation. [2] Direct hernias occur in older patients as a result of relaxation of abdominal wall musculature and thinning of the fascia.
