||||
show | lateral rotation
🗑

What is the CR for an AP ankle? | show 🗑
|
||||
show | 10 degrees posteriorly
🗑
|

show | w/o weights
🗑
|
||||
show | MTP & TMT joints
🗑
|
||||
show | base of 3rd metatarsal (exits posterior to malleoli)
🗑
|
||||
Which joints should be opened on the AP toes? | show 🗑
|
||||
show | either medial or lateral
🗑
|
||||
show | 1/2 distal metatarsal
🗑
|
||||
T or F: heads of metatarsals should overlap | show 🗑
|
||||
show | heads of metatarsals should appear directly side by side with no or only minimal overlapping
🗑
|
||||
which joint should be included on the axial calcaneus? | show 🗑
|
||||
How can you tell if the calcaneus is rotated? | show 🗑
|
||||
show | elongation
🗑
|
||||
Why is the tube angulation 40 degrees for the axial calcaneus? | show 🗑
|
||||

🗑
|
