Hip Anatomy Flashcards
What is pelvic girdle and lower limb
lower limb forms a joint with the trunk at the pelvic girdle
What makes up the pelvic girdle
formed from two innominate (hip) bones
What is the pelvis
basin shaped structure formed by the pelvic girdle and its associated sacrum
What 3 bones fuse to form the innominate hip bones
Ilium, ischium and pubis
What is the acetabulum
lateral surface on hip
deep depression that forms the hip joint with the almost spherical head of femur
Ilium:
upper flattened part of bone
has iliac crest and ASIS
What joint does the ilium form with the sacrum
forms a synovial joint–sacroiliac joint
Sacroiliac joint is:
a strong joint capable of absorbing the stresses of weight bearing
tends to become fibrosed later in life
What part is the pubis
anterior part of bone
Where does the pubis articulate with the other side pubis bone
pubis symphysis
What part of the hip is the ischium
inferior and posterior part
Where is the union of all 3 hip bones
acetabulum
What bears the weight of the body when sitting and what is it
ischial tuberosities– rough inferior projections of the ischia
Whats the longest and heaviest bone in the bahdy
femur
What type of joint is the hip
ball and socket
What encloses the head and most of the neck of the femur
capsular ligament
What stabilizes the hip joint without limiting its range of movement
acetabular labrum
What is the acetabular labrum
ring of fibrocartilage attached to the rim of the acetabulum
What are the 3 main external ligaments
iliofemoral, pubofemoral, ischiofemoral
localized thickening of the joint capsule
What attaches the femoral head to the acetabulum
ligamentum teres
not a typo
What are the bursae in the hip
iliopsoas bursa, trochateric bursa, gluteus medius bursa and ischiogluteal bursa
What are the movements of the hip joint
flexion extension abduction adduction medial rotation lateral rotation
What muscles flex the hip
psoas, iliacus and sartorius
What muscles extend the hip
gluteus max, hams
What muscles abduct the hip
gluteus medius and minimus, sartorius
What muscles adduct the hip
adductor group (longus, brevis and magnus)
What muscles medially rotate the hip
gluteus medius and minimus, adductor group
What muscles laterally rotate the hip
gluteus max, quads, obturators
What muscles are in the adductor group
Longus, brevus and magnus
What are the 4 muscles in the quad group
rectus femoris
vastis lateralis
vastis medialis
vastis intermedius
Where does the rectus femoris originate? Where does the other 3 vasti originate?
RF- ilium
V-upper end of femur
What is a very strong extensor of the knee joint
Quad group
