Toes
What are the routine projections, SID, and kVp of toes?
Projections = AP, AP oblique, Lateral
SID = 40”
kVp= 60 tabletop
AP Toes
Knees are ___ to place ___ surface of the foot on tabletop.
___ are in center of IR.
CR through ___ joint.
Cone down to the forefoot or the affected toe, depending on hospital protocol. (Some may prefer entire forefoot, others may want only toe of interest).
This projection demonstrates the ___ phalanges of the toes and ___ of the metatarsals.
AP Toes
Knees are FLEXED to place PLANTAR surface of the foot on tabletop.
TOES are in center of IR.
CR through 3RD METATARSOPHALANGEAL joint.
Cone down to the forefoot or the affected toe, depending on hospital protocol. (Some may prefer entire forefoot, others may want only toe of interest).
This projection demonstrates the 14 phalanges of the toes and DISTAL ENDS of the metatarsals.
Toes AP Oblique
___ rotate the foot from the ___ position so that the ___ surface forms an angle of ___° to the plane of the IR.
Direct CR through the ___ joint.
This projection demonstrates the toes and the ____of the metatarsals rotated ___.
Toes AP Oblique
MEDIALLY rotate the foot from the AP position so that the PLANTAR surface forms an angle of 45° to the plane of the IR.
Direct CR through the 3RD METATARSOPHALANGEAL joint.
This projection demonstrates the toes and the DISTAL ENDS of the metatarsals rotated MEDIALLY.
Lateral Toes
Position the foot for a ___ projection by turning patient’s foot toward ___ side.
To prevent ___ of the toes, use tape or another immobilization device to ___ the affected toe as much as possible.
Direct the CR through the ___ joints.
This projection should demonstrate a lateral projection of the ___ of the affected toe and open ___ joints.
Lateral Toes
Position the foot for a MEDIOLATERAL projection by turning patient’s foot toward AFFECTED side.
To prevent SUPERIMPOSITION of the toes, use tape or another immobilization device to ISOLATE the affected toe as much as possible.
Direct the CR through the METATARSOPHALANGEAL joints.
This projection should demonstrate a lateral projection of the PHALANGES of the affected toe and open INTERPHALANGEAL joints.
