|---|---|---|---|---|---|
| CR entry point for an AP axial foot | show 🗑
|
||||
| show | no rotation, equidistant midshafts of metatarsals 2-4, superimposed metatarsal bases 2-5, metatarslas tarsals and phalanges distal to talus included, open joint space between the medial and intermediate cuneiforms
🗑
|
||||
| Oblique foot structures shown | show 🗑
|
||||
| Oblique foot eval criteria | show 🗑
|
||||
| show | metatarsals nearly superimposed, distal leg included, fibula overlaps posterior half of tibia, tibiotalar joint open with superimposed domes, sufficient density to differentiate tarsals
🗑
|
||||
| show | plantar surface perpendicular to the IR with foot dorsiflexed
🗑
|
||||
| Structures shown in an oblique ankle | show 🗑
|
||||
| AP ankle eval criteria | show 🗑
|
||||
| show | if the fibula is to far posterior the ankle is over rotated. If it is seen anterior it is under rotated
🗑
|
||||
| Positioning for a mortise view of the ankle | show 🗑
|
||||
| show | ankle joint centered, tibiotalar joint well demonstrated, talar domes superimposed, fibula seen over the posterior half of the tibia, distal tibia, fibula, talus and adjacent tarsals, fifth metatarsal demonstrated for jones fracture
🗑
|
||||
| show | ankle and knee joints without rotation, tibiofibular articulations superimposed, fibular midshaft free of superimposition
🗑
|
||||
| show | distal fibula lying over the posterior half of the tibia, slight overlap of tibia over proximal fibular head, ankle and knee joints without rotation, femoral condyles superimposed, tibial and fibular shafts not superimposed
🗑
|
||||
| show | open femorotibial joint with equal joint spaces, knee fully extended, patella superimposed on the femur, no rotation, slight superimposition of fibular head, soft tissue around the knee joint, bony detail surrounding patella
🗑
|
||||
| show | Look for symmetric tibial plateaus, increased tibiofibular joint space indicates to much internal rotation.
🗑
|
||||
| show | femoral condyles superimposed, open joint space between femoral condyles and tibia, patella in profile, open patellofemoral joint space, fibular head and tibia superimposed, knee flexed 20-30 degrees,
🗑
|
||||
| show | lateral rotation of femoral condyles, patella, tibial condyles, and fibular head.
🗑
|
||||
| An AP medial oblique of the knee demonstrates what anatomy? | show 🗑
|
||||
| The settegast method or “sunrise” knee is done to visualize what? | show 🗑
|
||||
| Eval criteria for a lateral oblique of the knee | show 🗑
|
||||
| Eval criteria for a medial oblique of the knee | show 🗑
