Flashcards in complications of fractures Deck (22):
1

3 general ways to classify complications of fractures

1. timing - early, inter, late
2. bone or soft tissue
3. local or systemic

2

5 early complicastions

1. compartement
2. vasscular damage
3. neuro injury
4. malunion
5. RDS

3

what is compartment syndrome

1. elevation of intracompartamental pressure above perfusion pressure
- muscle necrosis and severe contracture

4

4 associations with compartment

1. fractures
2. crush injuries
3. tight casts
4. reperfusion injury

5

3 Sx of compartment syndrome

1. PAIN
2. short itme
3. if unconscious = no Sx

6

5 signs of compartment Syndrom

1. pain with passive stretch of muscle
2. pressure is high
3. paralysis
4. parathesia
5. pulseless

7

treat of compartment syndrome

- immediate fasciotomy
- leave wound open
- early detection and prevention key

8

what is vasc. damage

- surg emerg
- life and limb threateneing
- assoc with displaced fractures
- assess and record vasc. status

9

what is neuro injury

- assess and record distal function
- specifc fractures
- assess pattern and severity
-

10

treatment of neury damages

- expolre open injuries
- observe closed for a month
- explore closed in 3 months if not better

11

what is malunion

- reduction not obtained
- poor follow up or compliance

12

what is RSD

- associated with long bone fractures
- fat embolism syndrome
- early fixation preventative

13

7 intermediate complications

1. delayed union
2 non-union
3 stiffness
4. infection
5. compressive neurpathy
6. tendon ruptures
7. reflex symp dystrohy

14

causes of delayed unuion

- poor reduction
- inad. mobilization
- poor blood supply
- treatment adjustment usually reqiured

15

causes of stiffness

- prolonged immobilization
- inadequate rehab
- treat
- physio, splint, surgical release

16

3 causes of infection

1. open fractures
2. open reduction
3. hematogenous

17

treatment of infections

- drain
- debride dead bone
- AB
- secondary surgery

18

what is compressive neurpathy

-related to edema and pressures
- median, ulnar, peroneal common

19

what is RSD

- autonomic dysfunciton
- may occur withour fracure
- perm stiffness

20

2 late complications

1. avasc. necrosis
2. post-traumatic degen. arthritis

21

where is avasc. necrosis most common

femoral head

22

what is degen arthritis

- most with intra-articular fractures
- leasds to stiffness and pain
-
