Pelvis and hip Flashcards
Bony points
Iliac crest ASIS greater trochanter inguinal ligament public symphysis spinous and transverse processes of lumbar spine PSIS sacrum ischial tuberosity
Hip joint
- ball and socket joint - flexion, extension, abduction, adduction, medial/lateral rotation
- head of femur and acetabulum - acetabulum labrum to deepen the joint cavity
- covered in articular cartilage - thicker of places WB
Hip ligaments
intracapsular = ligament of head of femur extracapsular = iliofemoral, pubofemoral and ischiofemoral ligaments
sacroiliac joint
between sacrum and ilium - can be palpated
gluteus maximus
A: extension, lateral rotation, abduction of the hip (lower fibres adduct)
O: coccyx, sacrum, p. illiac crest, sacrotuberous/ sacroiliac ligaments
I: iliotibial tract and gluteal tuberosity
N: inferior gluteal
gluteus medius
A: abduction of hip, (anterior fibres) flex and medially rotate hip, (posterior fibre) extend and laterally rotate hip
O: gluteal surface of ilium, just below iliac crest, p/a gluteal lines
I: greater trochanter
N: superior gluteal
gluteus minimus
A: abduct, medially rotate and flex the hip
O: gluteal surface of ilium, a/I gluteal lines
I: greater trochanter
N: superior gluteal
adductor magnus
A: adduct and medially rotate the hip
O: inferior ramus of pubis, ramus if ischium, ischial tuberosity
I: adductor tubercle and medial lip of linea aspera
N: obturator/ sciatic
adductor longus
A: adduct and medially rotate the hip and assist hip flexion
O: pubic tubercle

N: spinal nerve
rectus abdominus
A: flex vertebral colum, posterior pelvic tilt O: public crest, pubic symphysis
I: cartilage of rib, xiphoid process
external obliques
A: (unilaterally)lat flex VC to same side, rotate VC to opposite side
(bilaterally) flex vertebral column O: external surface of rib
I: anterior iliac crest
