Chap7 pelvic proj.
Procedures1. Femur/pelvic projections.
|AP femur mid-distal, positioning? CR?||Rotate leg internally 5 degrees for true AP of knee. CR is perp. to mid femur.|
|Lateral femur mid/distal, positioning? How do you know its lateral?||Flex knee about 45 degrees. Anterior and posterior margins of medial and lateral femoral condyles are superimposed.|
|Lateral- mediolateral femur mid and proximal. Pt position? CR?||Lateral recumbent with affected leg down and knee bent to 45. Palpate ASIS and place upper IR margin at this level.|
|Lateral -mediolateral femur mid and proximal. Correct positioning eval?||Most of greater trochanter is superimposed by the neck of the femur, small part of greater and lesser may be visible medially.|
|AP pelvis. Pt position? CR?||females generally cannot be shielded. Separate pt legs, internally rotate lower limbs 15-20. CR midway between ASIS and symph pubis.|
|AP pelvis. Anatomy?||Pelvic girdle, L5, sacrum, coccyx, femoral heads and necks, greater trochanters. No rotation evident by symmetric wings, ischial spines, and obturator foramen.|
|Modified Cleaves method is what?||AP bilateral frog leg.|
|AP bilateral frog leg shielding? CR?||Since this is common for follow up exams for younger patients, shield male and females. CR 1 in above pubic symphysis.|
|AP bilateral frog leg pt position?||Supine arms across chest, flex both knees about 90, plantar surfaces of feet together and abduct both femora 40-45 degrees from vertical- BOTH need to be the same! Can use supports under knees. (don't need crest)|
