Tib/Fib
Distal Femur
Proximal Tibia
• Medial/Lateral ______________
– Processes on outer margins
• _______________ Eminence
– Medial and Lateral intercondylar tubercles
Proximal Tibia
• ________________
– Articular facets
• Tibial _______________
– Proximal anterior protrusion
• _____________ crest
– Anterior ridge
Proximal Fibula
• ____________
– Superior pointed portion of head
• Head
– Rounded aspect
• ____________
– Tapered area inferior to head
Tib/Fib
• 2 Joints
– ___________tibiofibular
– ___________tibiofibular
Tib / Fib Imaging
Routine
•
•
•
•
AP
Lateral
40” SID
65 kV
AP Tib / Fib
•
•
•
•
•
Pt Supine
Place _____________in AP.
Ensure ____________is on IR
Center at mid tibia
Collimate to skin
Lateral Tib / Fib
•
•
•
•
•
•
Position for mediolateral projection
Flex ___________
Place lateral aspect against IR
Ensure ____________is on IR
Center to mid leg
Collimate to skin
Distal Femur
Anterior
• ____________ Surface
– (Intercondylar Sulcus) (Trochlear Groove)
Smooth, Shallow depression.
• Shaft
– Body
Distal Femur
Posterior
• __________ Condyle
– Rounded distal portion medial
• ___________ Condyle
– Rounded distal portion lateral
• _________________ Fossa
– Notch between condyles
Distal Femur
Posterior
• Lateral _____________
– Lateral distal projection
• Medial ______________
– Medial distal projection
• _____________ Tubercle
–Off of posteriolateral aspect of medial condyle
Important Considerations
• Femur is _____________
– Angle between __________
• Medial Condyle
– More ___________ than lateral
• Adductor Tubercle
– Not seen on proper ______________
Distal Femur Imaging
Routine
•
•
•
•
AP
Lateral
40” SID
70 – 75 kV
AP Distal Femur
• Pt Supine
• Rotate leg ____________or until
interepicondylar line ________ with IR
• Ensure ____________is imaged
• Center to mid cassette
• Collimate to skin
Lateral Distal Femur
• Position for ____________ projection
• Place lateral aspect against IR
– May need to put ____________over affected
or posterior to affected
• Flex affected _____________
• Epicondyles _______________ to IR
• Center to mid cassette
