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

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.
