Foot Review Flashcards
The AP axial toe radiograph requires a CR direction of –1– degrees –2–.
15 degrees cephalic
For routine AP axial foot radiograph, the CR will enter the –1–.
Base of the 3rd metarsal
The 5th toe will require a –1– projection for best demonstration in the lateral position.
mediolateral
The AP medial oblique position of the toes requires the foot to be rotated –1– degrees.
30-45 degrees
The AP axial projection of the foot and/or toes may also be called the –1– projection.
dorsoplantar
The AP axial foot radiograph will require a CR angulation of –1– degrees.
10 degrees cephalic
When the foot is placed in a medial oblique rotation/position, the –1– and –2– will be demonstrated in profile.
- cuboid
2. 5th metatarsal
According to Merrill’s, the true lateral foot position/projection is the –1–.
lateromedial
When performing the lateral position foot, it is important to have the patient perform this action with their foot.
dorsiflexion
A lateral projection weight bearing foot is used to best demonstrate the –1–.
Longitudinal arch
When performing the weight bearing medial oblique projection of the foot, it is best to angle the CR –1– degrees –2– rather than have the patient rotate their foot while standing.
30 degrees medially
When performing the axial projection of the os calcis the patient should perform this action with their foot.
Dorsiflexion
Referring to the axial os calcis, the CR should be angled –1– degrees to the long axis of the foot/ os calcis.
40 degrees
Another name for the great toe is the –1–.
Hallux
When performing lateral toe positions/projections the biggest criteria is to –1–
see the toe without superimposition
Why is a cephalic angle preferred for the AP axial projections of the toe and foot?
to demonstrate open interphalangeal joint spaces
What is the sustentaculum ali and what tarsal bone is it a part of?
It is located on the medial portion of the os calcis and it supports the longitudinal ache of he foot
Why is there a range for rotating the foot for the medial oblique toe position?
Toes can overlap each other or be curled under one another
This SID for all foot radiography is –1–.
40 SID
The CR should be directed to the –1– for all AP axial and medial oblique views of the toes.
MTPJ
Bony detail is known as –1–.
Traberculae
For radiography of the sesamoids using a perpendicular CR the following methods are performed. List the position of the patient for these methods.
Lewis: –1–
Holly: –2–
- Prone
2. Supine
When performing the lateral os calcis, the projection used is a –1– and the CR will be directed to –2–.
- mediolateral
2. one inch inferior to the medial malleolus
What anatomy should be included on a lateral os calcis?
Ankle joint and surrounding tarsal bones
Lewis
C. prone pt/ sesamoids
Kite
A. congenital clubfoot
Holly
D. supine pt/ perpendicular CR
Coalition
B. Weight bearing clubfoot
Kandel
E. Weight bearing clufoot
The proper CR projection for a lateral great toe should be the –1–.
lateromedial
What is the function of sesamoids?
They are bones that are used as buffers for toes joints to prevent ware and tear (AKA protection)
What are the typical routine positions for a foot exam?
- AP axial
- AP medial oblique
- mediolateral lateral foot
What is the largest sesamoid in the body?
patella
What is the medical term for clubfoot?
talipes equinovarus
The most anterior structure of the shoulder girdle is the –1–.
coracoid process
What proximal shoulder structure should be seen in profile when an AP with external rotation is performed?
greater tubercle
