Trauma Imaging: Principles & Cervical Spine Flashcards
(30 cards)
What is the orientation of the fracture and the causative mechanism?
Oblique fracture due to compression
30-60 degrees
What is the orientation of the fracture and the causative mechanism?
Spiral fracture due to rotation with axial compression
What is the orientation of the fracture and the causative mechanism?
Transverse fracture due to tension/shear force
May be pathological
What type of fracture is demonstrated?
Comminuted
What is the diagnosis for the fracture of the radius and the causative mechanism?
Greenstick fracture
Angular/shear force (bending)
What is the diagnosis for the fracture of the ulna and the causative mechanism?
Torus fracture
Compressive/axial force
What is the diagnosis?
What radiographic sign is present?
Intracapsular fracture with effusion/lipohemarthrosis
FBI sign present
What is the diagnosis?
What radiographic sign is present?
Intracapsular fracture with effusion/lipohemarthrosis
Sail sign present
What is the diagnosis?
Gymnast fracture
distal radius
type 1 Salter-Harris fracture
What is the diagnosis?
What is the name for the fragment seen?
Type 2 Salter-Harris fracture
Thurston Holland fragment
through physis and metaphysis
What is the diagnosis?
What is the most emergent soft tissue structure likely damaged in this patient?
Posterior elbow dislocation
Ulnar and median nerves
reduction associated with fracture of coronoid process
What is the diagnosis?
What are some lesions associated with this injury?
Anterior shoulder dislocation
Associated with:
- Hill-Sach fracture (60%)
- Flap fracture (15%)
- Bankart lesion
- Labral tear
axillary nerve injury possible
What stage of fracture healing is the top picture in?
What stage is the bottom picture in?
Top: inflammatory
Bottom: reparative
What stage of fracture healing is this patient in?
A ild form of what complication has occurred?
Remodeling phase
Malunion
What complication has occurred?
Malunion
What complication has occurred?
Delayed union and non union
What are two radiographic findings in this view?
What is the diagnosis?
- Offset of lateral atlantoaxial alignment
- Wide paraodontoid space
Jefferson fracture
C1 burst fracture
What was the mechanism of this fracture?
Is it stable or unstable?
Axial compression
Unstable (transverse ligament is gone without arches intact)
Jefferson fracture
collar and emergency transport
What is the diagnosis?
How would this patient present?
Jefferson fracture
Positive Rust sign (holding own head) due to severe instability
can be neurologically intact
What radiographic sign is present?
Bow tie sign
unilateral facet dislocation
Which cervical line has the most pertinent abnormality?
Anterior body line displays slight anterolisthesis
unilateral facet dislocation
What is the diagnosis and mechanism of injury?
Is this stable or unstable?
Unilateral facet dislocation due to flexion with rotation (towards side of dislocation)
Stable until reduce, therefore treat as unstable
This x-ray was difficult to obtain due to severe acute torticollis.
What is the diagnosis?
Atlantoaxial rotary fixation
note asymmetry of paraodontoid spaces
What is the diagnosis?
How will this patient present?
Atlantoaxial rotary fixation
Acute torticollis
etiology can be post-traumatic or post-infectious
