  1. Chapter 8 Hip and Pelvis

  2. Proximal Femur • __________ – Round process • _________ – Depression in the center of the head • ________ – Area between shaft and head • ____________ • Cavity for head of femur

  3. Proximal Femur • _______________ – Superiolateral prominence • ______________ – Medioposterior prominence inferior to greater trochanter. • ________________ – Depression between trochanters

  4. Femur Angle • Not _________ • Angle of positioning importance • Head and neck = _______________. • Rotate legs ________________to get neck in true AP

  5. Hip Imaging Routine • AP Pelvis • Lateral • Frog Leg • X-table lateral • AP Unilateral Hip • 40” SID • 75 kVp

  6. AP Pelvis • Pt Supine • _____________________(Pigeon Toe) • Center Midline between ______and _______________ • Top of Cassette ____________Crest • Collimate to skin • If Trauma __________________*****

  7. Frog leg Lateral • Pt Supine • Flex knee and ________________ • A sponge may help • Center to Femoral Neck • Draw imaginary line between ______ and __________and go inferior _______perpendicular to line

  8. X-table Hip • Pt Supine • Do not move affected Hip • Unaffected Leg _____________. Can put leg on collimator • Use X-table grid parallel to __________ • Adjust collimator to be perpendicular to cassette.

  9. AP Hip • Patient Supine • Rotate Leg ______________ • CR directed ___________to femoral neck • __________and _________to ASIS

  10. Pelvis • Connects _________________to the axial skeleton • Consists of • ___________ • 1 sacrum • ______________. • Pelvic girdle – ______________only

  11. Hip Bones • _________ • Ischium • ___________ • Acetabulum – The area of fusion for the 3 bones.

  12. Ilium • _________ • Large winged area • ____________ • Inferior to the Ala. Includes superior acetabulum • _____________ • ASIS, AIIS, PSIS, PIIS.

  13. Ischium • Inferioposterior to acetabulum. • ___________ – Posterior acetabulum to ischial tuberosity • ____________ – Anterior portion off of ischial tuberosity

  14. Ischium • ________________ • Rounded, rough area at the border of lower body and Ramus • _______________ – Posterior bony protrusion off acetabulum • ______________ sciatic notch – Depression superior and inferior to ischial spine

  15. Pubis • Anterioinferior to acetabulum. • ___________ • Anteriorinferior acetabululum to superior ramus • ______________ – Anterior medial extensions meeting to form symphysis pubis. • _____________ – Inferioposterior extension off symphysis pubis to Ischial Ramus • _______________ – Hole formed by ischium and pubis

  16. True (Lesser) Area surrounded _________ _______ to pelvic brim _______ Inlet and Outlet False (Greater) Area formed by ________ __________ to pelvic brim True and False Pelvis

  17. Male ________ Deeper ______ Lesser pubic arch Narrow inlet Oval ________Foramen Female _______ More Flared Greater ________ Larger inlet Narrow Obturator Foramen Male vs. Female Pelvis

  18. Joints of the Pelvis • ______________ – Amphiarthrodial Synovial, Sacrum to pelvis • _______________ – Amphiarthrodial cartilaginous. Rt and Lt pubic bones • Union of Acetabulum – Synarthrodial cartilaginous. 3 fused hip bones • Hip Joint – Diarthrodial Synovial Spheroid.
