Ligaments
• Iliofemoral ligament• Ischiofemoral ligament• Pubofemoral ligament• Zona orbicularis• Sacrotuberous ligament• Ligament of the head• Transverse ligament of the acetabulum• Inguinal ligament
----------------Sacrotuberous ligament
Ligaments of the Head
Transverse ligament of the acetabulum------------>
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
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.
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
