tuberosity - 15The 1st cuneiform is between the _____ and the ____1st metatarsal
and
navicular - 16the cuboid is on the ____ side of the footlateral
- 17which tarsal bone is located directly anterior to talus?navicular
- 18Which tarsal bone is on the medial side between the talus and 3 cuneiforms?Navicular
- 19What is the name of the small space between the talus and calcaneus?Sinus Tarsi
- 20What bone is superior to the calcaneus?Talus
- 21Which cuneiform will articulate with the 3rd metatarsal?3rd cuneiform
- 22Which bones make up the ankle joint?distal tibia
distal fibula
talus - 23How can you tell if an x-ray of a lateral ankle is truly lateral?the distal fibula must superimpose half of the distal tibia
- 24For a standard oblique of the ankle, the ankle is in ___ degree rotation For the mortise the ankle is in ___ degree obliquity45
15-20 - 25How many bones are found in the foot?26
- 26What is the strongest and largest of the tarsal bones?Calcaneus
- 27The sustentaculum tali is found on the ____calcaneus
- 28What are some technical considerations for toes, feet, and ankle projections?-40 SID
-small focal spot
-table top - nongrid
-50-70 kVp
-10x12 or smaller IR
-place marker on lateral side of appendage - 29What are the routine studies for the toes?AP
Oblique
Lateral - 30AP Toes- CR < 10-15 degrees toward calcaneus @ MTP joint
- can use a 15 degree wedge w/ CR perpendicular as an alternative
- 31Lateral Oblique Toes- use lateral oblique for 4th and 5th digits to reduce OID
- CR perpendicular to IR @ affected digit's MTP joint
- 32Medial Oblique Toes- use medial oblique for 1st - 3rd digits to reduce OID
- CR perpendicular to IR @ affected digit's MTP joint
- 33Lateral Toe- CR perpendicular to IR
- directed to IP joint for 1st digit, and PIP for 2nd-5th digits
- 34Why are the lateral and oblique projections usually done mediolateral?It's easier for the patient to position their foot into a mediolateral projection - you get true laterals and better obliques when the patient can cooperate.
- 35What makes a digit x-ray repeatable?too much/too little rotation
exposure factors
MUST SEE up to half of the metatarsal
DO NOT COLLIMATE OFF DIGIT! - 36What are the routine studies for a foot?AP
Oblique
Lateral - 37AP Foot- CR < posteriorly toward the heel 10 degrees
- CR centered @ base of 3rd metatarsal
- 38AP Oblique Foot- location of foreign bodies
- CR perpendicular @ base of 3rd metatarsal
- should be at least 30 degrees obliqued
- 39Lateral (mediolateral) Foot- location of foreign bodies
- CR perpendicular @ medial cuneiform
- MUST HAVE at least 1 in of tib/fib shown with the open joint
- 40What makes a foot x-ray repeatable?coning off anatomy
rotation
exposure factors
motion - 41What are the routine views of the calcaneus?Plantodorsal Axial
Lateral - 42Plantodorsal Axial- foot should be flexed 90 degrees
- CR < 40 degrees cephalad from long axis of foot (down into the heel)
- center @ base of 3rd metatarsal to emerge at a level just distal to lateral malleolus
- 43Lateral (mediolateral) Calcaneus- CR perpendicular @ 1 in distal/inferior to medial malleolus
- angling the foot up slightly will open up the joint spaces for a true lateral projection
- 44What makes a calcaneus x-ray repeatable?coning off anatomy
rotation
exposure factors
motion - 45What are the routine views of the ankle?AP
Mortise
Lateral - 46AP Ankle- CR perpendicular @ point midway between the malleoli
- make sure the lower leg is not rotated!
- 47AP Mortise- Internally rotate entire leg and foot 15-20 degrees until intermalleolar line is parallel to IR
- CR perpendicular @ midpoint between malleoli
- should have space all around fibula
- 48Lateral (mediolateral) Ankle- use sponges to keep the foot and leg in true lateral position
- CR perpendicular @ medial malleolus
- 49*special* AP Oblique Medial Rotation- rotate foot and leg medially 45 degrees
- CR perpendicular @ midpoint between malleoli
- 50What makes an ankle x-ray repeatable?coning off anatomy
rotation
exposure factors
motion

- 52Which is the smallest of the cuneiforms?Intermediate Cuneiform
- 53Which tarsal is found on the medial side of the foot between the talus and cuneiforms?Navicular

- 56Which is the most superior tarsal bone?Talus
- 57Which bone articulates with the first metatarsal?Medial Cuneiform

- 62Which projection has the CR angled 10 degrees posteriorly into the heel?AP Foot
- 63Which projection has the CR angled 40 degrees cephalad into the heel?Inferosuperior Axial Calcaneus
- 64Which projection has the foot rotated inward 15-20 degrees?AP Mortise Ankle
- 65Which projection has the foot rotated inward 45 degrees?AP Medial Oblique Ankle
- 66Which projection best demonstrates the lateral mortise joint?AP Mortise
- 67Which projection best demonstrates the distal tibulofibular joint articulation?AP Medial Oblique Ankle
- 68Which projection best demonstrates the talus bone and medial joint?AP Ankle

Lateral Ankle
Lateral Foot - 74If you need more exposure time but your mAs and kVp need to stay the same, what should you do?Decrease mA
Increase time
