Sciatic nerve at the ischial tuberosity: 3D anatomy
Below gluteus maximus the sciatic nerve descends very close to the ischial tuberosity and the common hamstring origin. Tendon injury, fibrosis or a narrowed ischiofemoral space may affect it. This page shows that relationship in 3D, together with the tests that load it.
Anatomy of the passage

Next to the ischial tuberosity, the sciatic nerve passes close to the origin of the hamstrings. Tendon changes or fibrosis may limit its space and mobility. This site is described as the ischial tunnel or proximal hamstring syndrome within the differential diagnosis of gluteal pain.
