AA HIP / PELVIS
Radiology
| Question | Answer |
|---|---|
| AP Axial outlet pelvis ( Taylor Method) | Supine, CR at MSP 1" - 2" distal the pubis sym. At cephalic angle of 20 - 35 Males and 30 - 45 for Female; demonstrates pubis and ischium |
| AP FROG LEG | Supine, legs flexed 45 degrees w/ legs abducted 20 - 30 degrees from vertical; CR at MSP 3" below ASIS |
| Modified axiolateral hip (clement-nakayama method) | Supine, legs extended, IR at lateral side of hip, CR directed at femoral neck w/ a 15 - 20 degree angle downward, IR perp to CR; pt. Can not move legs |
| Unilateral frog leg (modified Cleaves method) | Supine / erect, same as bilateral except CR is at mid femoral neck perp to IR |
| AP AXIAL INLET PELVIS | Supine, legs extended, CR 40 degrees caudal at MSP at ASIS |
| Indicating rotation by looking at obturator foramen | Smaller or more closed up foramen will indicate that side closer to IR, also that side ilium will appear more flat or wider |
| Axiolateral I/S hip (Danelius Miller method) | Supine, elevate pelvis off table/bed, unaffected leg needs to move out, IR parallel to femoral neck at lateral side of hip, rotate leg 15-20 degrees internally CR perp IR and femoral neck |
| AP unilateral hip | Supine, leg rotate 15-20 degrees internally CR perp to femoral neck and IR |
| AP Bilateral pelvis | Supine / erect, legs rotated 15 - 20 degrees internally, CR perp IR at MSP 2" below ASIS; 1/2 way b/w the ASIS and PS. should not see lesser trochanters |
| Alternatives exam for the frog leg | Danelius - miller if the pt. can move good leg out of the way Clement - nakayama if the pt. has limited or no movement in legs |
| Lateral distal Femur | Lateral recumbent with affected knee flexed 45 degrees, good leg behind , IR bottom edge 2" below knee, CR perp IR at mid point of IR, must include knee joint. |
| Lateral proximal Femur | Lateral recumbent with pt. back off table 15 degrees, flex affected leg 45 degrees, CR perp IR at midpoint of IR, top of IR should be at ASIS, must include hip joint and all metal if any |
| AP Femur Distal | Supine, leg rotated 3-5 degrees, IR 2" lower than knee, CR perp to IR at midpoint of IR, must include knee joint |
| AP Femur Proximal | Same as unilateral hip, just get more femur and all metal if any |
