Anatomical Relations
The tendinous arch of pelvic fascia is a thickening of the inferior aspect of the superior fascia of the pelvic diaphragm. This fascia attaches from the posterior part of the body of pubis (anteriorly) to the ischial spine (posteriorly) (Dorland, 2011). This fascia blends with the obturator fascia lining the obturator internus and is continuous with the fascia covering the piriformis muscle.
Function
The tendinous arch of pelvic fascia provides a supportive attachment for the visceral pelvic fascia lining the urogenital organs within the pelvis.
