Heel/Os Calcis/Calcaneus Positioning Flashcards
What IR is used for a heel view?
10x12
What SID is used for a heel view?
40”
What are the structures seen for an axial plantodorsal heel?
- Calcaneus and subtalar joint is seen
- No rotation of the calcaneus
- Anterior portion of the calcaneus without excessive density over the posterior portion
How is the patient positioned for an axial dorsoplantar heel?
- Patient is placed in prone position
- Ankle elevated on sandbags
- Dorsiflex ankle to place the long axis of the foot perpendicular to table top
- Place IR to plantar surface of the foot
Where is the CR for an axial dorsoplantar heel?
Enters the dorsal surface of the ankle joint
How is the patient positioned for an axial plantodorsal heel?
- Patient is seated
- Plantar surface of foot perpendicular to IR
- Toes up
- Extremely dorsiflexed foot
- Hyperextended toes
Where is the CR for an axial plantodorsal heel?
Enters at base of 3rd metatarsal
What angle is the CR for an axial plantodorsal heel?
40-degree cephalic
What angle is the CR for an axial dorsoplantar heel?
40-degrees caudal
What are the structures seen for an axial dorsoplantar heel?
- Calcaneus and subtalar joint seen
- Sustentaculum tali is seen
- Anterior portion of the calcaneus without excessive density over the posterior portion
Why would a axial dorsoplantar be performed?
If the patient cant do a plantodorsal view
What view would be performed if the patient cant do a plantodorsal view?
Axial dorsoplantar
What are the structures seen for a mediolateral heel?
- No rotation of calcaneus
- Sustentaculum tali, sinus tarsi, and lateral tuberosity seen
- Ankle joint and adjacent tarsals
- Include medial malleolus and the base of the 5th metatarsal
How is the patient positioned for a mediolateral heel?
- Patient is recumbent
- Rolled up toward side of interest
- Dorsiflex foot
- Plantar surface of foot is parallel with IR
Where is the CR for a mediolateral heel?
Perpendicular to calcaneus about 1” distal to medial malleolus (at subtalar joint)
What view is the ankle joint and adjacent tarsals seen?
Mediolateral heel
In what view do you see the sustentaculum tali?
Axial dorsoplantar
In what view is the sustentaculum tali, sinus tarsi, and lateral tuberosity seen?
Mediolateral heel
