Superior and inferior rami
Superior rami
Continuous with arcuate line
Inferior rami
Connects with ischium to make pubic arch
Pubic arch
Pubis and ischio inferior ramus
Pubic arch in males and females

> 80 females
Ischiopubic ramus
Ramus if ischium meets with ramus of pubis

Order of posterior landmarks on hip from superior to inferior
PSIS PIIS Greater sc notch Ischial spine Lesser sc notch Ischial tuberosity
Sacrum what tilt and shape
Posterior tilt
Anteriorly concave
Coccyx
3-5 fused
No processes or foramena
No support but point of attachment for pelvic floor muscles
Lesser trochanter
Inf and medial
Greater trochanter
Sup and lateral
Female vs male
Female - shallow, ischial tuberosities everted
Male - ischial tuberosities longer, medial facing
False pelvis muscles
