The hip bones consist of 4 bones
- 2 hip bones
- Sacrum
- Coccyx
The hip bone is composed of what 3 divisions?
- ilium
- Ischium
- Pubis
The Ilium is located To the acetabulum
Superior
The ischium is And To the acetabulum
Inferior and Posterior
The pubis is And To the acetabulum
Inferior and Anterior
The crest (iliac crest) of the ilium is the superior margin of the ala; it extends from the Anterior Superior Iliac Spine (ASIS) to the Posterior Superior Iliac Spine (PSIS)
iliac Crest
What are the 2 important positioning landmarks of the pelvis?
- Iliac Crest
- ASIS
What do ASIS mean?
Angle of neck to shaft
- Avg adult= 125 degrees (+/-15) depending on width of pelvis and length of lower limb
- Ex:Long-leg/narrow pelvis-changes angle of neck to 140 degrees
- Ex: short/wider pelvis- angle 110 to 115 degrees
Longitudinal plane of femur
- 10 degree from verticle
- Vertical angle is nearer 15 degrees on wide pelvis/Short Limb ➡️ 5 degrees on long leg person
Head and neck in relation to body of femur
- 15 to 20 degrees anterior angle
- Head projects anteriorly/ forward
- In positioning femur must be rotated 15 to 20 degrees.This place for femoral neck parallel to the IR for true AP projection of the proximal femur
What is the meaning of the word pelvis?
The greater trochanter is located And To the femoral shaft
- Superiority
- Laterally
Lesser trochanter projects And From the junction of the neck and shaft of femur
- Medially
- Postetiorly
The trochanter are joined posteriorly by a thick ridge called
