Hip joint Flashcards
Does medial rotation of the femur move the greater trochanter forwards or backwards?
Forwards
What are the articular surfaces of the hip joint?
The femoral head and the lunate surface of the acetabulum
What is raised from the rim of the acetabulum?
The acetabulum labrum.
What does the acetabulum labrum form …ly?
The transverse acetabular ligament inferiorly.
What is the other name for ligament of head of femur?
The ligamentum teres.
What ligament attaches the fovea to the acetabular fossa, acetabular notch margins, and the transverse acetabular ligament?
The ligament of head or femur.
What artery does the ligament of the head of femur carry?
The obturator artery.
What are the three ligaments of the hip joint?
The iliofemoral ligament, the pubofemoral ligament, and the ischiofemoral ligament.
True or false?
The iliofemoral ligament is anterior to the hip joint.
True
What does the iliofemoral attach to? (both ilium and the femur)
In the ilium, it is located between AIIS and the acetabulum.
In the femur, it is located between the intertrochanteric line.
True or false?
The iliofemoral ligament is M-shaped
False, the iliofemoral ligament is Y shaped since the middle part of the intertrochanteric line aspect of the iliofemoral ligament is thinner.
True or false?
The pubofemoral ligament is separate with the fibrous membrane of the hip joint and the deep surface of the iliofemoral ligament.
False, it is continuous
What are the attachments of the ischiofemoral ligament on the femur?
The greater trochanter deep to the iliofemoral ligament.
What are the 4 gateways that connect the pelvic region to the lower limb?
- The obturator foramen - connect pelvis and the medial thigh
- The gap between inguinal ligament and the pelvis
- The greater sciatic foramen
- The lesser sciatic foramen
True or false?
The lesser sciatic foramen is divided into two parts.
False, the greater sciatic foramen is
What are the relations of the lesser sciatic foramen?
The lesser sciatic foramen is located inferior to the levator ani and coccygeus muscles.
What parts go through the inguinal ligament and the pelvic bone?
- Iliopsoas and pectineus,
pectineus muscles - Lymphatics
- Femoral branch of
genitofemoral nerve - Lateral cutaneous
nerve of thigh - Femoral nerve and vessels
What parts pass through the obturator canal?
- Obturator nerve
- Obturator vessels
What parts pass through the inferior of the piriformis muscle?
- Sciatic nerve
- Inferior gluteal nerve, artery, vein
- Pudendal nerve
- Internal pudendal artery and vein
- Posterior femoral cutaneous nerve
- Nerve to obturator internus and
gemellus superior muscles - Nerve to quadratus femoris and
gemellus inferior muscles
What vessels pass through the suprapiriformis foramen?
- Superior gluteal nerves and vessels
What structures pass through the lesser sciatic foramen?
- Obturator internus muscle tendon
- Pudendal nerve and internal pudendal
vessels pass into perineum
from gluteal region
What foramen does the obturator internus pass through?
The lesser sciatic foramen
