Q

What are common special tests for fractures?

A

Squeeze, percussion/tap, fulcrum, axial compression, tuning fork.

17
Q

What imaging confirms fractures?

A

X-ray, CT, MRI.

18
Q

Define a closed fracture.

A

Bone breaks without piercing the skin.

19
Q

Define an open fracture.

A

Bone pierces skin, creating open wound.

20
Q

Define an avulsion fracture.

A

A tendon or ligament pulls a piece of bone away.

21
Q

Define a greenstick fracture.

A

Incomplete break in bones not fully ossified (common in adolescents).

22
Q

What are growth plates called?

A

Epiphyseal plates.

23
Q

What classification system is used for growth plate fractures?

A

Salter–Harris classification.

24
Q

General fracture management principles?

A

Control bleeding, cover wounds, immobilize above & below, splint in position found, monitor ABCs, check distal pulses.

25
What is a dislocation (luxation)?
Acute injury where a bone is displaced from its joint.
26
Signs/symptoms of dislocation?
Pain, deformity, swelling, diffuse tenderness, muscle spasm, pop felt, inability to use limb.
27
How are dislocations treated initially?
Immobilize, refer, do NOT reduce unless trained, check for shock, get X-ray.
28
What is a subluxation?
A partial dislocation that reduces itself spontaneously.
29
Signs/symptoms of subluxation?
Pain, swelling, tenderness, spasm, ↓ function, pop felt, NO deformity.
30
What can recurrent dislocations or subluxations lead to?
Ligamentous laxity and muscle weakness.
