Flashcard 4: In Iliotibial Band Syndrome, pain develops secondary to friction of the iliotibial band against the _____

Answer: lateral femoral epicondyle

Flashcard 5: Obstruction of the _____ causes symptoms similar to those seen in SVC syndrome, but only on one side of the body

Answer: brachiocephalic vein

Flashcard 6: Piriformis syndrome is caused by hypertrophy or injury to the piriformis muscle, compressing structures traveling through the ____. Name the 8 structures passing below the piriformis muscle:

Answer: Greater sciatic foramen 1. Sciatic nerve 2. Inferior gluteal nerve 3. Inferior gluteal vessels 4. Internal pudendal vessels 5. Pudendal nerve 6. Posterior cutaneous nerve of thigh 7. Nerve to obturator internus 8. Nerve to quadratus femoris

Extra: Structures passing through the greater sciatic foramen (GSF) are categorized by their relationship to the piriformis muscle: **Above Piriformis:** 1. Superior gluteal nerve 2. Superior gluteal artery 3. Superior gluteal vein **Below Piriformis:** 1. Sciatic nerve (most commonly compressed in Piriformis Syndrome) 2. Inferior gluteal nerve 3. Inferior gluteal vessels 4. Internal pudendal vessels 5. Pudendal nerve 6. Posterior cutaneous nerve of thigh 7. Nerve to obturator internus 8. Nerve to quadratus femoris *Note: The pudendal nerve and internal pudendal vessels pass out of the GSF and back into the lesser sciatic foramen to reach the perineum.*
