Q

Shoulder abduction orthosis

A

Holds shoulder in slight abduction, decreases contracture and g force on shoulder

Side pillow and neck/waist strap, ball for hand

19
Q

Airplane orthosis

A

Soft chest piece and pauldron that holds shoulder at large (almost horizontal) angle of abduction. Provides immobilization and/or controlled ROM

20
Q

Shoulder abduction rotation orthosis

A

“Waving” position

Rigid side and arm piece that immobilizes arm for palsy or contracture prevention.

21
Q

The hyoid bone is at what vertebral level?

A

C3

22
Q

The sternal notch is at what vertebral level?

A

T1

23
Q

The xiphoid process is at what vertebral level?

A

T10

24
Q

The spine of the scapula is at what vertebral level?

A

T3

25
Q

The inferior angle of the scapula is at what vertebral level?

A

T7

26
Q

The belly button is at what vertebral level?

A

L2

27
Q

The iliac crest is at what vertebral level?

A

L4

28
Q

The ASIS is at what vertebral level?

A

S1/S2

29
Q

Movement of the lumbar vertebrae

A

Flexion/extension
Lateral bending
Almost no rotation

30
Q

True or false

The thoracic portion of the vertebrae is the most mobile.

A

False

The thoracic portion is the LEAST mobile because the ribs restrict movement

31
Q

Movement of cervical vertebrae

A
  • Most mobile portion of spine
  • movement in all three planes
  • carries vertical force of skull
32
Q

Guilford cervical orthosis

A

Rigid low-profile collar and “suspenders.” Metal bar in front and back for support. Difficult to don and doff.

NOT for patient who is intubated!

Provides increased immobilization compared to other CO’s

33
Q

Sternooccipitomandibular Immobilizer (SOMI)

A

Interchangeable headband and chin piece.

Controls cervical flexion but not extension

34
Q

HALO

A

Can only be used with no existing skull fractures

Used for spinal realignment and to maintain stability

Adult - 4 pin sites @ 8lbs pressure
Children - usually 6 pin sites @ 4lbs pressure

35
Q

Jefferson cervical fracture

A

Fractures of the anterior and/or posterior arches of the atlas (C1)

36
Q

Odontoid fractures

A

3 types

  1. Tip only (stable, semi-rigid CO)
  2. Base (most severe/unstable, needs HALO or surgical fusion
  3. Body of the dens (may need HALO or SOMI)
37
Q

Cervical SpondyLOSIS

A

Abnormal wear on vertebrae. Space between the vertebrae narrows and begins to press on nerves emerging from spinal cord.

38
Q

SpondyLOLYSIS

A

Usually effects L4/L5

Stress fracture of the “spinous process”

Common in active teens and young adults

39
Q

SpondyLOLISTHESIS

A

Vertebral slippage as a Progression of spondylolysis

Grade 1: 0-25%
Grade 2: 26-50%
Grade 3: 51-75%
Grade 4: 76-99%
Grade 5: 100%
40
Q

Boston overlap brace

A

Custom fab, lightweight brace for back injuries and pain. Anterior overlap opening with straps.

41
Q

Ankylosing spondylitis

A

Ossification of vertebral joints (bamboo back)

Gradually increasing pain, stiffness, and flexion

42
Q

Jewett orthosis

A

3-point pressure system to hold back in extension, to relieve compression fractures.

Kinesthetic reminder

43
Q

CASH orthosis

A

Cruciform Anterior Spinal Hyperextension Orthosis (cross chest)

For anterior spinal compression fractures of T10-L3

44
Q

ATE

A

Anterior thoracic extension for an LSO to make it a TLSO
