Q

Spondylosis → Intervertebral dis generation is a

A

Normal, active, age related process involving both genetic, biomechanical and environmental factors which cause disruption of the chemical constituents of the cartilaginous annulus fibrosis and inner gel like nucleus pulposus

Q

Spondylosis → Resulting process

A

Micro tears in the AF, escape of the NP a decreased disc space, reduced shock absorption and flexibility.
The vertebra and the synovial joints then develop compensatory degenerative changes typical of the changes of osteoarthritis namely osteophytes, loss of joint space, subchondral sclerosis and subchondral cysts3.

Q

Intervertebral Disc Prolapse →Definition

A

Very simply, each intervertebral disc, which is located between each vertebra, is composed of an outer ring of cartilaginous annulus fibrosis (red arrow) and an inner centre of gelatinous nucleus pulposus (green Arrow).

When an intervertebral disc prolapses, as has occurred in the adjacent diagram, the central nucleus pulposus is forced or extruded posterolaterally causing the annulus fibrosis to bulge, a complete prolapse occurs when the nucleus pulposus extends beyond the annulus fibrosis.

Q

Extrusion impinges on the spinal nerve roots and spinal cord.

26
Q

Osteomyelitis Definition

A

As an infection of bone, but more specifically vertebral osteomyelitis, when the vertebral bodies become infected, can occur.

27
Q

Osteomyelitis Common infecting organism in the UK is

A

Staphylococcus aureus followed by E. coli, Pseudomonas and Proteus.

28
Q

Osteomyelitis Routes of bacterial spread

A

Direct or haematogenous (via the venous plexus of Batson).

29
Q

Osteomyelitis Method of diagnosis

A

MRI

30
Q

Osteomyelitis Pathologically

A

Is an infection with a subsequent inflammatory response, abscess formation (like the tuberculous “Potts abscess”), ischaemia and hence bone death (sequestrum). New bone can also occur (involucrum) as can the development of sinuses (cloacae) in severe disease which then discharge pus.

31
Q

Osteomyelitis Presentation of pathology

A

This can present as a swelling in the groin from a psoas abscess.

32
Q

Osteomyelitis Pain caused diminished by

A

Movement and muscle spasms

33
Q

Osteomyelitis Signs of

A 
Systemic infection
Fever
Malaise
Fatigue
Raised WCC
ESR
34
Q

Osteomyelitis Examination shows

A

Dramatic loss of range of movement
Local tenderness
Deformity such as gibbus from TB

35
Q

Osteomyelitis Xray findings for osteomyelitis

A

Plain Radiographic Changes in Vertebral Osteomyelitis
No changes visible for the first few weeks.
Then evidence of intervertebral disc space narrowing and loss of disc height.
Localised osteopaenia.
Sclerosis.
Reactive new bone formation.
Soft tissue swelling and a paravertebral mass.
Later development of vertebral collapse and kyphosis. (Gibbus)

36
Q

Osteomyelitis Special investigations

A 
Blood tests
Blood cultures
Biopsy
Radioisotope bone scanning
MRI
37
Q

Treatment for osteomyeltisi

A

Bed rests
Analgesics
IV antibiotics for six weeks (triple therapy for TB) the oral antibiotics
Occasionally surgical removal of dead bone
Drainage of abscesses

38
Q

Cauda Equina syndrome → Definition

A

is a surgical emergency, requiring immediate referral. It is a rare condition in which the cauda equina component of the spinal cord, located below the level of L2, becomes compressed

39
Q

Cauda Equina syndrome → Responsible for producing

A
  • Sphincter disturbance leading to bladder or bowel dysfunction (either incontinence or retention)
  • Gait disturbance
  • Saddle anaesthesia
  • Bilateral lower limb weakness if untreated or missed
  • Sexual dysfunction
  • Muscular pain
  • Numbness
  • Paraesthesia
40

Prostate
Kidney
Thyroid
42
Q

Vertebral bodies in thoracic and lumbar spine

43
Q

Metastatic Bone Disease → Spread is

A

Haematogenous

44
Q

A

Persistent, severe and at night

45
Q

Metastatic Bone Disease → Presenting features

A

Swellings

Hypercalcaemia and pathological fractures and features such as weight loss, fatigue and anaemia.

46
Q

Metastatic Bone Disease → Investigations reveal

A

Elevate ESR and alkaline phosphatase and low haemoglobin

47
Q

Metastatic Bone Disease → Late radiographs show

A

OSteolysis with bone destruction due to stimulation of osteoclasts

48
Q

Metastatic Bone Disease → Other investigations

A

MRI

Radioisotopes

49
Q

Metastatic Bone Disease → Primary lesion is prostate carcinoma

A

The radiograph can differ having osteoblastic deposits

50
Q

Metastatic Bone Disease → Treatment

A

Curative or palliative using a combination of
1. Analgesia
2. NSAIDs
3. Radiotherapy
4. Hormonal therapy
5. Surgery
to make the patient as symptom free as possible.

51
Q

Multiple Myeloma → PRIMARY Definition

A

Definition

(myeloma or plasma cell myeloma) is a disorder representing the accumulation of malignant plasma cells in the bone marrow resulting in the over production of immunoglobulin, predominantly monoclonal IgA, IgG and IgD (Bence-Jones protein a free monoclonal antibody of Kappa and gamma light chains).
52
Q

Multiple Myeloma → PRIMARY Causes

A

Causes secondary hypocalcaemia, anaemia and renal damage if not managed early

53
Q

Multiple Myeloma → PRIMARY Characterised by

A

Diffuse osteoporosis, usually in the pelvis, spine, ribs, and skull. The displacement of normal marrow causes a susceptibility to bacterial infection.

54
Q

Multiple Myeloma → PRIMARY Patient predominance

A

Elderly men
African (slightly more)
Less in Asians(suggest genetic)

55
Q

Multiple Myeloma → PRIMARY Exposure risks

A

Populations exposed to large amounts of radiation, such as survivors of the atomic disasters, have an increased risk for myeloma. Most individuals with multiple myeloma have no recognised predisposing pathologies. However, exposure to petroleum products, insecticides, herbicides, plastics, heavy metals, and asbestos appear to be weakly associated risk factors for the disease.

56
Q

Multiple Myeloma → PRIMARYEffects

A

Bone destruction resulting in fractures and vertebral damage and hence back pain, recurrent infections, renal impairment and anaemia

57
Q

Multiple Myeloma → PRIMARY Clinical Features

A 
Bone pain
Anaemia
Renal Failure
Infection
Neurological symptoms
58
Q

Multiple Myeloma → PRIMARYTreatment

A

Is an incurable progressive condition in which treatment aims to correct and slow the progression and includes chemotherapy, anticytokine therapy, with interferon alpha and interleukins, and supportive measures with bisphosphonates and erythropoietin.

59
Q

yellow flags

A

→ The belief by patients that back pain is harmful and potentially severly disabling:
• The fear-avoidance behaviour in patients and hence reduced activity levels.
• The patients with a tendency to low mood and withdrawal from social interaction.
• The expectation by patients that passive treatments rather than a belief that active participation will help.
