Q

What is the purpose of the Cervical spine? (2 things)

Study These Flashcards
A
  1. Supports head
  2. Provides motility
22
Q

How are C spine fractures classified in terms of region? (3 regions)

Study These Flashcards
A

Type 1 = Occipital condyle + Craniocervical junction
Type 2 = C1 ring + C1/2 joint
Type 3 = C2 + C2/3 joint

(pic shows Occipital condyle)

23
Q

How are C spine fractures classified in terms of fracture type? (3 things)

Study These Flashcards
A

Type A = Bony injury only
Type B = Tension band injuries
Type C = Translation injuries (dislocation)

24
Q

What is the Tension Band in the spine?

Study These Flashcards
A

Group of muscles / ligaments / processes / pedicles

that maintain integrity of vertebral column

25
What are the possible clinical features of a C spine fracture?
1. Neck pain (doesn’t present if there are other concurrent injuries) 2. Neuro involvement: * Sensory / motor deficit * Defected innervation to diaphragm * Poor vasomotor tone (determine artery pressure) 3. Post circulation stroke (if vertebral artery injured)
26
What are some different diagnosis of C spine fractures? (3 things)
1. Cervical spondylosis 2. Cervical dislocation 3. Whiplash
27
What are some named types of C spine fractures? (2 things)
1. Hangman’s Fracture 2. Odontoid Peg Fractures
28
What is a Hangmans Fracture also known as?
Traumatic spondylolisthesis of axis
29
What is a Hangmans Fracture? (2 things)
1. # thru pars interarticularis of C2 bilat. 2. Subluxation (partial dislocation) of C2 onto C3
30
What is a Hangmans Fracture caused by?
Cervical hyperextension (getting hung by a noose innit)
31
What is required if a Hangmans Fracture is unstable?
Surgical fixation
32
What is a common cause of Odontoid peg fractures?
Low impact injury in elderly
33
Can Odontoid peg fractures be fatal?
Yeah, esp w significant displacement of odontoid
34
Those who survive Odontoid peg fractures have no X?
Neurology
35
What rules determine if a pt needs imaging for C spine fracture?
Canadian C spine rules
36
Who qualifies to even be considered by the Canadian C spine rules? (2 things)
1. Glasgow Coma scale 15/15 2. Stable condition
37
Who does the Canadian C spine rules say needs imaging? (3 things)
1. 65+ yrs 2. Dangerous mechanism 3. Paraesthesia in extremities
38
Who does the Canadian C spine rules say does NOT need imaging? (5 things)
1. Simple-rear end motor vehicle collision 2. Waiting in sitting position 3. Ambulatory at any time 4. Delayed onset neck pain 5. Absence of midline C spine tenderness
39
If Canadian C spine rules say someone does not need imaging, what should be done instead?
ROM assessment
40
What scans does Canadian C spine rules say should be done for adults vs children?
``` CT = adults MRI = children ```
41
How should a patient w sus C spine fracture be managed?
Per ATLS guidelines, including: 3-point C-spine immobilisation
42
Why should movement of the spine be restricted in a sus C spine fracture?
To prevent spinal cord damage cah movement at level of unstable # can cause neurological defect
43
What are the indications for NON-operative management of C spine fractures? (2 things)
1. Stable #s 2. Pt in which surgiacal intervention is risky
44
What are the non-operative management options of C spine fractures? (3 things)
1. Rigid collars 2. Halo vests 3. Traction devices
45
What are Rigid collars used for in non-operative management of C spine fractures?
Immobilisation of C spine # extrication + initial assessment
46
What are Halo vests used for in non-operative management of C spine fractures?
When more rigid support is needed Non-operative Unstable C spine #s
47
What is a Halo vest (non-operative management of C spine fractures)? (3 steps)
1. Pins placed in outer table of skull under local 2. Pins connected to Halo device 3. Device mounted on thoracic brace
48
When are Traction devices used as definitive treatments for in non-operative management of C spine fractures? (2 things)
1. When surgical treatment risky 2. When # reduction required (e.g facet joint dislocation)
49
What is the indication for Operative management of C spine fractures?
Unstable #
50
What are the Operative management options for C spine fractures? (2 things)
1. Fusion 2. Stabilisation
51
What is the Fusion operation for C spine fractures? (2 things)
1. Fusing injured segment of spine to uninjured segments above + below 2. +/- decompression of vertebral canal
52
What is the Stabilisation operation for C spine fractures?
Fragments fixated using pedicle screws and rods | (Patient lying prone)
