Flashcards in Orthopedic Surgery 1 & 2 Deck (41):
1

What are the important things to evaluate with a fracture (Fx)?

- open or closed
- identify the bone
- location and pattern of fx (transverse, oblique, comminuted; break in more than one location...)
- displacement/angulation

2

How do you treat NONdisplaced CLOSED fractures?

- placed in a splint or cast for definitive treatment.
*monitor soft tissue swelling.

3

How do you treat DISPLACED CLOSED fractures?

- reduced to anatomic position and may be treated in cast or may need surgery.

4

What are OPEN fractures?

- a break in the skin and underlying soft tissue leading directly into or communicating with the fx and its hematoma.
*do NOT use term "compound" fx.

5

**** What is the Gustilo system of classification? (TEST QUESTION)

- emphasis on size of skin injury (minor or major soft tissue involvement) in OPEN fxs, used for prognosis.
*the higher you go on the scale, the more likely for bone deformities or infection.

6

What are TYPE 1 OPEN fractures?

- INSIDE-OUT injury
- clean wound
- minimal soft tissue damage
- no significant periosteal stripping

7

What are TYPE 2 OPEN fractures?

- OUTSIDE-IN (can bring bacteria in) mechanism
- moderate soft tissue damage
- higher energy injury
- some necrotic muscle, some periosteal stripping

8

What are TYPE 3A OPEN fractures?

- OUTSIDE-IN injury
- high energy
- extensive muscle devitalization
- bone coverage with existing soft tissue is not problematic.

9

What are TYPE 3B OPEN fractures?

- OUTSIDE-IN injury
- high energy
- extensive muscle devitalization
- requires a local flap or free flap for bone coverage and soft tissue closure.
- periosteal stripping

10

What is a TYPE 3C OPEN fracture?

- Type 3B with major vascular injury requiring repair.
- increased risk of amputation.

11

**** What is the most important thing to remember with OPEN fractures? (TEST QUESTION)

ANTIBIOTICS
- Type 1 and 2= 1st generation cephalosporin.
- Type 3= add aminoglycoside.
- severely contaminated or farm-type injuries= add penicillin.
*always check tetanus status.

12

What is important to remember in regard to films?

- get films of the joint ABOVE and BELOW the fracture.

13

What is a hemiarthroplasty?

- procedure which replaces one half of the femur or humerus whilst leaving the other half intact when the blood supply has been disrupted by a fracture.

14

How could you treat a closed right midshaft transverse humerus fracture?

- hanging arm cast -OR-
- intramedullary Rod with screws proximal and distal to the rod to prevent the bone from rotating around the rod (think of it like a shish kabob).

15

What is a Monteggia fracture?

- fracture of the proximal third of the ulna with dislocation of the head of the radius.
*treat with plat and screws

16

What makes pediatric fractures different from adult fractures?

- growth plates
*this is why pediatric cases are more commonly treated with closed reductions (casting) vs. surgery, to reduce the risk of growth plate disturbance with surgery.

17

How do we treat a femoral head fracture?

- stabilize with plates and screws
- replace with titanium head (hemiarthroplasty with cerclage wire); usually for elderly.

18

How do you treat a patellar fracture?

- tension band wire= converts a displacing force into a compression force

19

What is normal knee flexion ROM?

- about 180 degrees

20

When do fibular fractures need to be repaired?

- when they are more distal around the ankle due to stability requirements.

21

How do you treat a severely infected metal prosthetic?

- replace with antibiotic infused cement balls, which are implanted for 6 weeks along with IV antibiotics, and then if cultures are negative, replace with new implant.

22

**** A 30-year old male in a MVA has a closed comminuted fracture of the proximal tibia. He was admitted to the hospital and is schedule for surgery in a day or so. He is complaining of severe pain and is asking for narcotics. His leg is swollen, tense, and the pain is substantially worse with flexion. What is the next step in treatment? (TEST QUESTION)

- Go to the OR for an emergent fasciotomy

23

**** A 20-year old gymnast is out and slips. She is now experiencing ankle pain. The next day she visits the PCP with a swollen ankle and in pain. What diagnostic study should be ordered? (TEST QUESTION)

- X-ray

25

**** A 40-year old male laborer is experiencing back pain that radiates to the right leg has a positive SLR and a positive contralateral SLR. This has been present for a few weeks and is getting worse. He is experiencing tenderness at the lumbar spine, sciatic scoliosis, and a diminished patellar reflex. You suspect sciatica. Which nerve root is affected? (TEST QUESTION)
