UNC MSK Course Day 3 Lab XR UNKNOWNS(for self study)
Anatomy, name?
Ilium
Anatomy?
Ischium
Anatomy?
Pubic and ischial rami
Anatomy?
Acetabulum and femoral head
Anatomy?
Pubic symphysis and Obturator foramen
Anatomy?
Femoral neck Greater trochanter Lesser trochater
Name of bone?
Innominate
Pathology?
Fracture of Ilium into acetabulum
Pathology?
Fracture of Ilium into acetabulum Swelling & hematoma iliacus, gluteus maximus
Pathology?
Dislocation SI joint Fractures rami Fracture femoral neck
Pathology?
Anterior dislocation hip
Anatomy?
Lateral or frog leg view of hipGreater trochanterLesser trochanter
Pathology?
Fracture of femur in child
Anatomy?
PatellaFibular headMed & lat epicondylesMed & lat condylesMed & lat tibial plateaus
Pathology?
Varus knees with mild medial compartment degenerative arthritis.
Patient has had a valgus producing osteotomy on R to relieve pressure on medial compartmentNormal is 5-10 degrees valgus alignment between the fermoral and tibial shafts. Is 0 degrees in this patients L knee and so he is actually in varus mechanically.Medial compartment joint space narrowing and small osteophyte
Anatomy?View?
Anatomy?PatellaView?Sunrise view
Pathology?
Pathology?
Patella fracture.Difficult to see on AP view.
Pathology?
Bicondylar tibial plateau fracture.
Anatomy?
This is a coronal plane MRI. What are the arrowed structures?
ACLPCLMCL
Medial and lateral meniscii.
This is a saggital plane MRI. What compartment of the knee is this slice through?
What are these structures?The presence of the fibula tells us it is through the lateral compartment.
Patellar tendon (ligament)Anterior and posterior horns of the lateral meniscusThe presence of the fibula tells us it is the lateral compartment.
What is this structure?
ACL
What is this structure?
PCL
Pathology?
Degenerative tear posterior horn medial meniscus (its not solid black like it should be).
Healthy lateral meniscus is solid black
T2 weighted MRI of same degenerative tear posterior horn medial meniscus.
Pathology?
Fracture tibia and fibula

Pathology?
Pathology?
Fracture of fibula (hard to see on lateral view - this is why it is often said that you MUST have two views)
