All of Foot Flashcards
The axial os calsis projection will require the CR directed –1– degrees to the long axis of the foot to demonstrate the os calsis free from superimposition.
40 degrees
The oblique toe position will require the foot rotated –1– degrees.
30-45 degrees
The lateral foot will require the foot be placed in –1– of 90 degrees by flexing at the ankle.
Dorsiflexion
The standard lateral foot will utilize a –1– projection, whereas a “true” lateral foot will utilize a –2– projection.
- Mediolateral
2. Lateromedial
The CR is dircted to the –1– for the AP axial foot projection.
Base of the 3rd metatarsal
AP, or AP axial foot- centering doesn’t change
The anterior surface of the foot is also termed the –1– surface.
Dorsal
The oblique position of the foot will demonstrate a lateral process called the –1– and the –2– (tarsal bone) in profile.
- Tuberosity of the 5th metatarsal
2. Cuboid (only metatarsal with a specific name)
The degree of obliquity, for the internal/medial rotation foot position, required is –1– degrees.
30 degrees
Which projection of the oscalsis, lateral, or AP axial, will best demonstrate the sinus tarsi?
Lateral
The CR is directed –1– degrees –2– for the AP axial dorsoplantar projection of the foot. Why is this direction preferred?
- 10 degrees
- towards the heel (to the long axis of the foot)
- To open up the joint spaces
The medical term for the 1st toe is the –1–.
Hallux
Which bones articulate distally with the cuneiforms?
1, 2, and 3 metatarsals
Which tarsal bone is located laterally and between the oscalsis and the 4th and 5th metatarsals?
Cuboid
The sesamoid bones are best demonstrated with the use of a –1– CR projection which just skims the surface of the foot.
Tangential
The Lewis Method will utilize the CR being directed –1– to the IR. The foot is positioned in –2–.
- perpendicular
2. Dorsiflexion
The Causton Method will utilize the CR being directed –1– and the foot is positioned in a –2–.
- 40 degrees toward the heel
- lateral position (lateromedial)
(removed from Merrills)
The lateral projection of the 1st toe will require the –1– projection.
Lateromedial
The lateral projection of the foot with weight bearing will best demonstrate the –1–.
longitudinal arch
The lateral foot position should demonstrate the –1– superimposed.
Metatarsals
What position of the foot will best demonstrate the sinus tarsi?
AP Oblique with medial rotation
When performing the WB medial oblique foot position, the CR should be directed –1– degrees –2–.
- 30 degrees
2. medially
Where is the CR directed to for a lateral foot?
Perpendicular to the base of the 3rd metatarsal
When performing an axial WB oscalsis (coalition), the CR is directed to a point that is –1–.
on the plantar surface at the level of the base of the 5th metatarsal
What is the sustentaculum tali and on which oscalsis position is it best demonstrated?
Dorsoplantar Axial projection?
What 2 methods are utilized for congenital clubfoot?
Kite and Kandel
What foot position is the radiograph?
AP Oblique medial rotation
Label the anatomy and identify.
A. Distal phalange of the great toe B. Proximal phalange of the great toe C. Tuberosity of the 5th metatarsal D. Cuboid E. Navicular F. Sinus Tarsi
What was the CR direction to the IR?
perpendicular
Where was the CR directed to on the foot?
base of the 3rd metatarsal
What degree formation was there between a line drawn through the bases of the metarsals to the film? –1–
What was the degree formation to the CR? –2–
- 30 degrees
2. 60 degrees
