Answer 2

Anteriorly- pubic symphisis & posteriorly at sacroiliac joints.

Question 3

What type of cartilage is at pubic symphysis?

Answer 3

Fibrocartilage

Question 4

What are the movements at the hip joint?

Answer 4

Flexion, extension, abduction, adduction, medial & lateral rotation, circumduction.

Question 5

What are the bony features of ilium and what is their significance?

Answer 5

Inferior, anterior and posterior gluteal line.

Question 6

What bones articulate to form the hip joint?

Answer 6

Synovial articulation between head of femur and lunate (covered by cartilage) surface of the acetabulum of pelvic bone.

Question 7

What type of joint is the hip joint?

Answer 7

Multiaxial ball and socket joint.

Question 8

What ligament runs across the acetabulum?

Answer 8

Transverse acetabular ligament.

Question 9

What ligament runs from head of the femur to acetabular fossa?

Answer 9

Ligament of the head of the femur. - carries a small branch of obturator artery to supply head of femur.

Question 10

Which ligaments stabilise the hip joint?

Answer 10

Iliofemoral, pubofemoral, ischiofemoral.

Question 11

What is the vascular supply to the hip joint?

Answer 11

1. Branches of the obturator artery
2. Medial/Lateral circumflex femoral artery
3. Sup/inf gluteal arteries
4. First perforating branch of the deep artery of the thigh

Question 12

What nerves supply the hip joint?

Answer 12

1. Femoral nerve
2. Obturator nerve
3. Superior gluteal nerve
4. Nerve to quadratus femoris

Question 13

What is a hip pointer?

Answer 13

A contusion of the iliac crest and/or the greater trochanteric region of the femur following a direct impact or collision. American football and hockey are the most common sports that result in these injuries. Hematoma develops around the area and often includes varying degrees of bleeding into the hip abductor - sartorius, gluteus medius musculature.

Question 14

What are the gateways to the upper limb?

Answer 14

1. Obturator foramen
2. Greater sciatic foramen
3. Lesser sciatic foramen
4. Space between inguinal ligament & anterosuperior margin of pelvis.

Question 15

What is in the greater sciatic foramen?

Answer 15

Piriformis muscle. Superior gluteal nerve and arteries above piriformis. Below it has waaaaay more things :
1. Sciatic nerve
2. Inferior gluteal nerve and vessels
3. Pudendal nerve
4. Internal pudendal vessels
5. Nerve to both gemelluses, ob internus and quadratus femoris.
