title: [Anatomo-surgical considerations on the inguinal region. II. The internal oblique muscle and transverse muscle].
abstract: Following a previous note on the musculus obliquus externus, attention is now directed to the obliques internus and the transversus in an assessment of the anatomical formations of the groin, in the light of doubts concerning their constitution expressed in the recent literature, and in a critical appraisal of the hernioplasty techniques proposed. Data from the cadaver, which appear to be of particular interest, show muscle-aponeurosis fissures in both the obliquus parvus and the obliquus externus; these may be the cause of recurrent hernias. The differences in the extent of the muscle and aponeurosis portions of the obliquus internus and the greater or lesser area of the trigonum inguinale, which is covered by aponeurotic fibres of the transversus, are regarded as important factors in the genesis of inguinal hernia.
