The obturator internus muscle has an important relation to the pathology, andalso to the treatment of a certain class of dislocations. This muscle, from itsorigin in the obturator membrane and bony borders of the foramen, withinthe pelvis, converges its fibres into a tendon, which passes to the lesser sciaticnotch and winds around a trochlear surface, to be inserted into the digitalfossa on the great trochanter of the femur. The position of this muscle a
