26
Q

In a major haemorrhage, how much blood can you lose into your long bones?

A

1.5L

27
Q

In a major haemorrhage, how much blood can you lose into your pelvis?

A

Your whole circulating volume!

?Pelvic binder (apply to greater trochanters)

28
Q

How might you manage a patient who has come in with an animal bite to their finger?

A

Check Neurovascular status and tendons (CRT, pulses, sensation, motor), tetanus status
Washout and debride!
PO augmentin (co-amox)
Review in 2-3d if it might need closure

29
Q

How might you manage a patient who has come in with a human bite over his MCP joint*?

A 
X-ray for teeth - high risk of septic arthritis
Neurovascular exam and tendons
Washout and debridement 
PO or IV Co-amoxiclav
Consider and explain BBV risk
30
Q

On an X-ray how might you tell if someone has had multiple shoulder subluxations?

A

Bankhart lesion - anterior glenoid labrum injury

Hill-sachs lesion - humeral head dip

31
Q

What tests can you perform to test for subacromial impingement?

A

Painful arc test
Neers impingement sign - Pain on passive forward flexion >90
Hawkins test - pain on passive forward flexion to 90 and IR

32
Q

What are the different types of hip fractures? (look up images)

A

Subcapital
Transcervical
Intertrocanteric
Subtrochanteric

Garden classification

33
Q

What is the difference between a Monteggia and a Galeazzi fracture?

A

Monteggia - Proximal ulnar f# with proximal radioulnar joint instability

Galeazzi - Distal radial shaft f# with distal radioulnar joint instability

34
Q

What causes trigger finger?

A

Constriction or thickening of the A1 pulley or nodules on the tendon

Finger stuck in flexion and painfully click on extension, worse in am

35
Q

When would patients with a suspected disc prolapse get investigated with MRI?

A

> 6 weeks of radicular pain who have failed conservative therapy or patients who have developed a neurological deficit

Bilateral lower limb deficit or peroneal nerve injury sx - Urgent referral to on call ortho - rule out CES

36

Loss or altered function*
Abnormal Ix or examination

38
Q

What Plain film views do you need to diagnose SUFE?

A

Frog legged lateral and AP

39
Q

A child presents with hip and groin pain, refusal to weight bear and a limp. On questioning you find out they have had a recent viral URTI*, what might they have?

A

Transient synovitis

If they have a fever - Urgent treatment for suspected septic arthritis - make sure you safety net about fever in transient synovitis!

40

41
Q

What might Paget’s disease look like on X-ray?

A

Bone enlargement and deformity
“Osteoporosis circumscripta” describes well defined osteolytic lesions that appear less dense compared with normal bone
“Cotton wool appearance” of the skull describes poorly defined patchy areas of increased density (sclerosis) and decreased density (lysis)
“V-shaped defects”/ blade of grass: in the long bones are V shaped osteolytic bone lesions within the healthy bone

42
Q

What is the MoA of bisphosphonates?

A

Reduce bone turnover, they accumulate in osteoclasts and cause they to apoptose

43
Q

How do you take Alendronic acid?

A

Weekly
First thing in the morning, with nothing else (on en empty stomach), 30min before breakfast or any calcium/milk, sitting upright for 30min

44
Q

What are some side effects of bisphosphonates?

A

ON of the jaw
Atypical femoral fractures (subtrochanteric)
Oesophagitis
Hypophosphataemia

45
Q

How can you treat DDH in <6m?

A

Pavlik harness - flexed and abducted

46
Q

How can you treat DDH in >6m?

A

Closed reduction or
?open reduction
Spica cast for 3m

47
Q

What is the webers classification for ankle fractures? (A-C)

A

A - below the level of the syndesmosis
B - at the level of the syndesmosis
C - above the syndesmosis

48
Q

What is the Ottawa rules for an ankle X-ray?

A

An ankle x-ray is required only if there is any pain in the malleolar zone and any one of the following findings:

  • bony tenderness at the lateral malleolar zone
  • bony tenderness at the medial malleolar zone
  • inability to walk four weight bearing steps immediately after the injury and in the emergency department
49
Q

What injury to the knee swells up really quickly?

A

ACL - it is very vascular
