Flashcards in Fractures & Imaging Deck (18)
Loading flashcards...
1
Things to consider when assessing a fracture (7)
- Open vs. closed
- Location
- Degree (complete vs. incomplete)
- Articular extension
- Comminution/pattern
- Intrinsic bone quality
- Displacement, angulation, rotation
2
Complete fracture
Extends completely thru bone (2 cortices)
3
Incomplete fracture
Does not extend completely thru entire bone thickness (1 cortex)
4
What to look for with spiral fractures?
Associated fractures
5
How are spiral fractures typically caused?
Low forced torsion injuries
6
Toddler w/ spiral fracture alerts you for...
Abuse
7
Segmental fracture
2 adjacent fractures w/ isolated central segment
8
Pathologic fracture
Fracture in bone weakened by abnl condition (cancer, osteoporosis, etc)
9
What could you see on xray of stress fracture?
- Initial might be neg
- Sometimes only clue is callus formation (new bone being laid down)
10
Comminuted fracture
Shattered bone
11
Compression fracture
Bone fractured by 2 other bones (vertebral bodies)
12
Salter-Harris fracture
Through growth plate (important in peds)
1. S=slipped
2. A=above
3. L=lower
4. T=through
5. R=rammed
** 1 & 2--usually minor
** 3-5--poorer prognosis
13
What MSK problems can be seen on xray?
- Fractures & callous formation
- Dislocations
- Tumors/cysts
- Soft tissue
- Metabolic changes (osteopenia, excess bone, etc)
14
Gold standard imaging for soft tissue
MRI
15
Contrast injected into joint to evaluate soft tissue of joints before MRI, CT, or xray
Arthrogram
16
Xray, CT, and contrast media used to eval space bt bone and soft tissue
Myelogram
17
Visual real-time intra-articular structures (Contrast injected into joint to evaluate soft tissue of joints before MRI, CT, or xray)
Arthroscopy
