Q

What is the aetiology of Scheuermann’s disease?

A

Considered part of osteochondrosis family. This means that it is characterised by avascular necrosis to the epiphysis and later regrowth of the bone.

Q

What are the clinical features of spondylolysis?

A

Unilateral back pain

Pain may radiate to buttocks or legs

Restricts daily activities

Worsens with strenuous activity and lumbar hyperextension

Pain on completion of stork test - see next slide

Unilateral tenderness on palpation

16
Q

How do we manage symptomatic spondylolysis?

A

Activity restriction

Abdominal exercise to increase core strength and stabilise spine

Bracing - Boston brace - most common treatment of acute spondylolysis

Surgery - used especially if condition progresses to high grade spondylolisthesis

17
Q

What is the aetiology of spondylolisthesis?

A

Displacement (normally anteriorly) of one vertebra relative to its immediately inferior vertebral body

18
Q

What is the most common cause of spondylolisthesis in adolescents?

A

Spondylolysis

19
Q

Is spondylolisthesis the same as a slipped disc?

A

No. A slipped disc is more correctly termed a spinal disc herniation and refers to when one of the discs in between the vertebrae has ruptured. This is not the case in spondylolisthesis where the vertebrae itself has moved.

20
Q

Where is the spine is spondylolisthesis most commonly found?

A

Lumbar spine

21
Q

What are the clinical features of spondylolisthesis?

A

Generalised lower back pain - intensified on sneezing or coughing

Stiffening of the back

Leaning forwards (kyphotic) posture - compensatory change

Waddling gait

22
Q

What is the radiological sign associated with traumatic spondylolisthesis?

A

Scotty dog appearance

23
Q

How do we manage someone with spondylolisthesis?

A

Mild: Physio and analgesia

More severe: surgery (spondylolisthesis with spinal stenosis is one of the most common indications for spine surgery (laminectomy) among older adults)

24
Q

What is vertebral osteomyelitis?

A

Infection of the vertebral body

25
Q

What are the clinical features of vertebral osteomyelitis or discitis?

A

Severe pain on weight bearing and walking

Local tenderness

Known for subtleness in onset

Fever

Swelling at joint

More advanced disease will present with muscle spasm

26
Q

What are the organisms that most commonly cause vertebral osteomyelitis?

A

Staph aureus - can be MRSA

Streptococcus equisimilis

27
Q

In addition to imaging, what investigation might you do for someone in whom you suspect vertebral osteomyelitis?

A

Fine needle aspiration

28
Q

How do we manage vertebral osteomyelitis?

A

IV antibiotics for weeks to months

If severe or unresponsive to antibiotics surgery may be indicated for debridement and spinal fusion

29
Q

What is scoliosis?

A

Lateral curvature of the spine associated with rotational deformity.

30
Q

What percentage of children are affected by scoliosis?

A

4%

31
Q

What are the causes of scoliosis in children?

A

About 65% are idiopathic - adolescent idiopathic scoliosis (AIS)

Vertebral abnormalities:
Hemivertebra
Osteogenesis imperfecta
Spina bifida

Neuromuscular disorders:
Polio
Cerebral palsy
Muscular dystrophy

Other:
Dysmorphic syndromes such as neurofibromatosis, Marfan syndrome, Prader-Willi syndrome and CHARGE syndrome

32
Q

Is scoliosis more common in boys or girls?

A

Girls

33
Q

What are the clinical features of idiopathic scoliosis?

A

Pain - not always a typical feature in childhood

Lateral curvature of the spine on inspection

Rotation of thoracic spine on flexion

Rib hump (prominent shoulder blade) on bending forwards

34
Q

What are the possible complications of scoliosis?

A

Diminished lung capacity

Pressure exerted on heart

Constipation due to tightened organs from curvature

Untreated severe disease will result in later degenerative changes, pain and unwanted cosmetic appearance

35
Q

How do we manage scoliosis?

A

Mild cases: not treated

Moderate: braced for 23 hours a day until growing has stopped

Severe (more than 40˚): requires surgery that fuses the spine and therefore termination further growth

36
Q

What is the more common name for acute torticollis?

A

Wry neck

37
Q

What is wry neck or acute torticollis often associated with in children?

A

Upper respiratory tract infection

38
Q

What is the most common cause of torticollis in children?

A

Sternomastoid tumour found in the first few weeks of life

39
Q

How do we treat torticollis?

A

The disease is self limiting and should be managed with analgesia.

If the cause is a sternomastoid tumour, physio and stretching should be encouraged. It will usually resolve within the 1st year of life.

Surgery is reserved for persistent cases.
