Obturator internus muscle

Last revised by Assoc Prof Craig Hacking on 25 Aug 2021

The obturator internus muscle, like the piriformis muscle, is both a muscle of the pelvic wall and of the gluteal region. It originates within the pelvis, and continues as a flattened tendon posteriorly through the lesser sciatic foramen (between ischial spine and tuberosity).
