Tibia and Fibula Flashcards
what is the CP for a AP tib/fib
perpendicular to the Midpoint of the leg
what is the CP for a lateral tib/fib
perpendicular to the Midpoint of the leg
what is the patient positioning for a lateral tib/fib
what is the sponge used to do
patient lie on affected side and bend unaffected knee and move leg back
sponge under heel to ensure lateral ankle and lateral knee
what is the image critique for a AP tib/fib
in terms of what should be superimposed and what shouldnt
Partial superimposition of fibula and tibia at proximal and distal ends, Shaft of Tibia and fibula should not be superimposed
Femoral and tibial condyles in profile, parallel to IR
Knee and tibiotalar joint spaces closed (CR mid tib fib)
what is the image critique for a lateral tib/fib
in terms of the fibula
Proximal head of fibula superimposed by tibia
Distal fibula superimposed over posterior half of tibia
Don’t expect to achieve a true lateral knee and lateral ankle
what is the area of interest for a AP Tib and fib
Knee and ankle joints demonstrated
entire fib and tib
what is the area of interest for a lateral Tib and fib
lateral knee and ankle joints demonstrated
what is the SID for tib/fib views
100-110cm
what is the kV for tib/fib views
60-65kV
what is the mAs for tib/fib views
4-5mAs
do you use grids for tib/fib views
no
