Q

How do the uncinate processes affect lateral flexion in the cervical spine?

A

due to the increased height of the uncinate processes, the cervical segments must medially translate while laterally flexing (opposite to in the lumbar spine where they laterally translate during lateral flexion)

22
Q

What are the functional divisions of the thoracic spine?

A

C7-T4 cervicothoracic
T4-T8 mid thoracic
T8-L1 thoracolumbar

23
Q

Is there movement coupling at the thoracic spine?

A

yes- axial rotation with ipsilateral lateral flexion (however it is weak)

24
Q

Yes or No: Reduced thoracic mobility at T1-4 can affect neck rotation range.

A

Yes

25
Q

What is the clinical implication of hypomobility throught the thoracic spine?

A

neck movements rely on some extension at the C7-T4 thoracic spine therefore stiffness here can affect the neck movements

bilateral arm elevation requires thoracic extension so this can also be affected

26
Q

Yes or No: Unilateral arm movement requires 20 degrees of T4-8 rotation.

A

No

27
Q

How much T4-8 thoracic extension is needed to achieve arm elevation?

A

15 degrees

28
Q

What movement occurs in the ribs during thoracic flexion, lateral flexion and exhalation?

A

anterior rib rotation + superior glide

29
Q

What movement occurs in the ribs during thoracic extension, rotation & inhalation?

A

posterior rib rotation + inferior glide

30
Q

What should your first question to your patient be?

A

why have you come for treatment today?

31
Q

What information in the patient interview would raise your suspicion of possible underlying cancer?

A

night pain

past history of bowel or breast cancer

unexplained weight loss

32
Q

Name some red flags that may come up in a patient interview regarding neck pain.

A

anterior neck pain suggesting heart issues

bilateral symptoms with multiple joints involved/inflammatory indicators

generally unwell, raised temperature suggesting infection

non-mechanical pain/night pain/unexplained weight loss suggesting cancer

acute onset severe, unusual pain suggesting arterial dissection

craniovertebral anomalies as seen in downsyndrome or congenital absence of ondontoid peg leading to instability at C2

33
Q

If a patient reports long-term use of steroid medication, why would this raise concerns for treating their neck or thoracic spine?

A

osteoporosis which would contraindicate manual therapy

pathological fractures which would need further investigation

34
Q

Compare typical features of nociceptive and neuropathic sources of pain.

A

articular= localised, pain increased with movement towards side of pain/compression, ipsilateral blocks to movement, referral patterns

muscular= spreading pain, prologned positions, movements away from side of pain/stretch, worse with repetitive movement/tiring of muscle

discogenic= localised or diffuse, cloward’s sign, pain associated with loading/towards end of day

neural= sharp/burning/p&n, dermatomal, irritable, latency, worse with nerve tension

35
Q

Yes or No: Plain Xrays are best because they have less radiation and can see soft tissue and nerves.

A

No

36
Q

Yes or No: If a person cannot rotate their neck 45 degrees post trauma, they need an Xray?

A

Yes

37
Q

What effects does exposure to long-term ionising radiation have?

A

deterministic effects (risk of skin damage)
stochastic effects (risk of cancer)

38
Q

How much radiation are we exposed to normally in a year?

A

2mSv

39
Q

Name 2 rules that can be used to determine the need for a cervical spine plain Xray?

A

Nexus, Canadian C spine.

40
Q

What are the Canadian C Spine rules?

A

Yes for xray=

high risk factors (>65 years, dangerous mechanism or paresthesias in extremities)

unable to safely examine ROM

unable to rotate neck 45 degrees

41
Q

What are the benefits to using Xray over other imaging?

A

most available, cost-effective, quick, physio can refer (for spine & hips)

42
Q

What are the benefits to using CT over other imaging?

A

good for multiple views/positions that are uncomfortable to xray due to #, good bone detail, some soft tissue detail (though still not as good as MRI), fine slice better than MRI

43
Q

What are the benefits to using MRI over other imaging?

A

best soft tissue views (though expensive, long wait times and only specialist can refer with rebate)

44
Q

What are T1 and T2 MRI techniques used for?

A

T1= anatomical detail i.e. bony
T2= nerve/spinal cord detail (water in tissues)

45
Q

What are the contraindications for an MRI?

A

Pacemaker, metal in eye, metallic stents, some aneurysm clips, neural stimulators, cochlear implants.

46
Q

Yes or No: MRI can give better views of the bony structures than CT scan.

A

No

47
Q

Yes or No: Denis 3 column refers to 3 columns used to determine instability.

A

Yes

more than 1 column damaged= instability

48
Q

Lateral Xray film is important first when considering instability.

A

Yes

49
Q

Generally how thick should the anterior neck soft tissue be in a lateral view of an MRI?

A

at C2= ~6mm
at C6= ~2cm

50
Q

What is the power ratio and what is it exploring?

A

a ratio that describes the stability or instability of the craniocervical junction

if the ratio is >1, this indicates anterior instability (i.e. the head has moved forward on the neck)

if the ration is <0.8, this indicated posterior instability (i.e. the head has moved backward on the neck)

51
Q

What is the rule of twelves (Harris’ Measurements) and what is it exploring?

A

a set of measurements that describe the stability or instability of the craniocervical junction

there should be ~12mm between the top of the dens and the base of the skull, and ~12mm between the base of the skull to the imaginery line running up from the front of the vertebral body

more than this suggests ligament disruption/instability

52
Q

What are the 3 types of odontoid fracture?

A

type 1= tip of the dens (odontoid), rare, stable
type 2= base of the dens, common, unstable
type 3= through dens & into lateral mass of C2, relatively stable if not displaced, best prognosis due to large surface area for healing

53
Q

Compare neuropathy and mechanosensitivity.

A

neuropathy involves issues with nerve conduction due to mechanical compression or chemical irritation, whereas mechanosensitivity involves issues with how the nerve glides through surrounding tissues
