10. Bursae
Trochanteric Bursa- separates the deep aspect of the gluteus maximus from the greater trochanter of the femur
Gluteofemoral Bursa- separates the iliotibial tract from the superior part of the proximal attachment of the vastus lateralis (in textbook)
Ischial Bursa- separates the inferior border of the gluteus maximus from the ischial tuberosity

18. Piriformis Syndrome
An uncommon neuromuscular disorder that is caused when the piriformis muscle compresses the sciatic nerve. The piriformis muscle is a flat, band-like muscle located in the buttocks near the top of the hip joint. This muscle is important in lower body movement because it stabilizes the hip joint and lifts and rotates the thigh away from the body
Starts with pain, tingling, or numbness in the buttocks. Pain can be severe and extend down the length of the sciatic nerve (called sciatica). The pain is due to the piriformis muscle compressing the sciatic nerve, such as while sitting on a car seat or running. Pain may also be triggered while climbing stairs, applying firm pressure directly over the piriformis muscle, or sitting for long periods of time.
