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

18

Most important initial tool in fracture dx

Xray
