What reinforces the Retinacular vessels?
Superior and inferior gluteal arteries (internal iliac A)
26
What is the significance of the foveal artery
Supplies epiphysis with small amount of blood during skeletal development Becomes destroyed in adult life (ligamentum teres)
27
What is the classification of hip fractures?
Intra-capsular; ABOVE inter-trochanteric line Extra-capsular- BELOW inter-trochanteric line.
28
What class of hip fracture have the greater risk of disrupting blood flow to femoral head
INTRA-CAPSULAR- disrupt retinacular vessels
29
What are the Garden classes of intra-capsular fractures?
Type 1- incomplete, impacted in vagus Type 2- complete, undisplaced Type 3- complete, partially displaced Type 4- complete, completely displaced
30
Which garden fracture has a higher risk of disrupting femoral head blood supply and why
Type 3&4- greater displacement Unlike type 1&2 where there’s minimal displacement
31
In the elderly what is likely the cause of hip fractures?
Falls; directly or twisting when foot is planted and body rotates Bones are osteopaenic and deficient in elastic reserve
32
In younger patients what are the most likely causes of hip fractures?
High energy trauma Gait disturbances (multiple sclerosis) Corticosteroid use
33
Why can falls occur
Mechanical; sliding and slipping Precipitated by stroke, MI, UTI, chest infection etc
34
How can hip fractures be diagnosed?
Radiologically However may be suspected clinically
35
What are the symptoms of hip Fracture
Hip/knee pain on affected side Inability to bear weight Limited range of motion
36
What are the signs of hip fracture
Bonny tenderness over affected hip Shortened or externally rotated leg (present if significant displacement occurs)
37
What are the bedside investigations needed to aid diagnosis and look for complicating pathology?
Observations Urine dip ECG- required pre-op. ACS, undiagnosed arrhythmia
38
What are bloods investigations
FBC U&E CRP Clotting Group and save
39
What are imaging investigations?
Chest XR: required pre-op Plain films: need to image entire length of femur , hip, pelvis, knee MRI/CT: only if plain films are inconclusive also to rule out OCCULT fracture Cardiac echo: if new murmur is auscultation or abnormal ECG, required pre-op
40
How can you interpret the X-ray to rule out or confirm fracture of the hip
Shenton’s line- continuous and smooth in absence of fracture
41
Where is the Shenton line drawn across?
Drawn along inferior border of superior ramus and along inferomedial border to proximal femur
42
How are hip fractures treated? ANY EXCEPTIONS?
SURGICALLY Except wen there are co-morbidities
43
How does surgical management differ?
Depends on whether it is intra or extra capsular fractures
44
What is involved in conservative treatment and what are the outcomes for the patient ?
Involves traction, bed rest or restricted mobilisation Outcomes are often very poor
45
What is the NICE guidelines for hip surgery? Why
Surgery performed on day or 1 day after admission To allow patient to fully weight bear immediately after post-op period. This is not often possible
46
What does NICE recommend for Gardens 3/4 displaced fracture treatment?
Total hip replacement for FIT patients Hemi-arthoplasty for patients with significant comorbidity
47
What is the treatment procedure for Garden 1/2?
Cannulated hip screws (2 or 3 of them)
48
What is the treatment procedure for Extra-capsular fractures?
Dynamic hip screw or Intra-medullary nail
49
What is unique about dynamic hip screw treatment?
Allow fracture ends to slide; promotes bone healing
50
what are the risk factors for falls in the elderly?
* Postural hypotension * neurological- poor vision, confusion * environmental- poor lighting steep stairs. furntiture not at right height for patient * fear of falling
51
what are the causesof postural hypotension?
* ageing * low blood circulation * grugs- for high BP
52
what are fragiltiy fractures?
occurs from mechanical forces that wouldnt normally result in fracture (low energy trauma). it can even happen without falling but its normally from a fall
53
what is the major risk for fragiltiy fracture-
reduced bone mineral density such as seen in osteoporosis however it can occur in patients without osteoporosis
54
what are the causes of fragiltiy fractures?
* fall * lifting * coughing * banging into something
55
what is a characterisitc of osteoporosis?
low bone mass, microarchitectural disruption and skeltal fragiltiy loss of horizontal trabeculae in spongy bone (more porous)
56
when do people who have osteoporosis realise that they have it?
when they have fallen and have a fracture
57
why are females more at risk of osteoporosis than men, explain the pathophysiology
menopause; less oestrogen secretion theres more bone resorption than formation- more osteoclast activity than osteoblast oestrogen reduces osteoclast activity and increases osteoblast activity
58
what happens to the bone with age; that increases risk of osteoporosis
Bone marrow become syellow- adipocytes formed no osteoblasts made
59
what are the risk factors for osteoporosis
age, gender (female), Hypocalcaemia
60
how does hypocalcaemia increase risk of osteoporotic fracture?
less calcium in blood, increased PTH secretion and hence more osteoclast activity
61
what scan is used to diagnosed osteoporosis?
DEXA scan- T score of less than -2.5 (compared with healthy 25 yr old individuals) Z score; compared with healthy people with same age bracket
62
what are the potential causes of hypocalcaemia?
* low calcium in diet * low sunlight * liver diease * kidney disease * inactive vit D receptors
63
what is the mechanostat theory?
Regulatory mechanisms in bone adjusts to strain placed on it to meet demands. low starin = low bone density (homeostasis and energy conservation). High strain = high bone density Above strain therhold theres only bone formation (osteob last activity)
64
Describe this fracture, its severity and treatment options
Garden 2; high chance of damaging vessels. treatment- dynamic hip screw or cannulated hip screw
65
what is sarcopenia and what are it's risk factors
loss of skeletal muscle mass and strength risk facitrs: age, gender, physcial activity lead to death, falls, low BMD (mechanostat theory as increased muscle mass put more strain on bone)
66
why do people die due to falls?
* HEART FAILURE * infection, HAI * Co-morbidities
67
what are the different types of drugs used to treat osteoporosis?
* Teriparatide- PTH competitive inhibitor * Raxofeine * Zoledronic acid- given IV, Bisphosphonate; ihibit osteoclast, help in mineralisation using calcium hydroxyapatite * Alendronic acid- given to Mrs Wilkins; taken orally daily or weekly contraindications are acid reflux and upset tummy. **Oestrogen receptor modulator -reduce vertebrae fracture** * Strontium renalte- cause myocardial infarction, used as last basis * Denosumab- monoclonal antibody, given subcutaneously 6 monthly * HRT- young premature menopause * ibandronate- bisphosphonate- given orally monthly or IV 3 monthly
68
what is the technique needed to look for fractures?
Look at cortex of bone and see if its smooth line- fracture is where there's break in the line.
69
what are the contraindications of giving Alendronic acid?
acid reflux or upset tummy
70
why other supplements are given to those with osteporosis?
Vit D and calcium
71
why is it important to refer to falls clinic after?
help in rehabilitation- MDT team of physiotherapist, OT, geriatric team et.c can help
72
what are the factors of delirium?
* Dehydration * opoids- cause bowel problemwhich exarcebate it * change in medication * MCI * sleep deprivation * triedness * infection * electrolyte dysfunction * Age
73
how can delirium be combated in hospital setting?
* Bring familiar objects * continuity of care * relatives- remind them and talk in short sentences * rehydration * meal time buddies- red tray to encourage eating * 24hr clock * don't move between wards unnecessary * don't give medication unless they seriously pose harm to themselves or others, give low doses * dont give unnecessary noise at night or in wards
74
Describe this fracture and its severity. Give treatment options
Intratrochanteric fracture- doesnt affect retinacular vessels as much treamtnet Intramedullary nail or DHS
75
Describe this fracture, its severity and treatment options
Garden 4; no shenton line seen. Very high chance of disrupting retinacular vessels treatment- total hip replacement or hemiarthroplasty where the acetabulum (in blue) is still in place
76
What are the symptoms of compression fractures?
* Pain and morbidity associated with high doses of analgesia. * Loss of height. * Difficulty breathing. * Loss of mobility. * Gastrointestinal symptoms. * Difficulty sleeping. * Symptoms of depression.
77
What are the component of post-op care?
* Pain control. * Antibiotic prophylaxis where appropriate. * Monitoring of FBC and correction of postoperative anaemia where required. * Routine systems examinations to detect complications early or exacerbation of existing comorbid conditions. * Regular assessment of cognitive function. * Prevention and management of pressure sores. * Monitoring of nutritional status and renal function. * Monitoring of bowel and bladder function, and management of problems as required. * Wound care. * Early mobilisation.
78
What are the symptoms of delirium
* Being more confused than normal * Changes in alertness – such as being either unusually sleepy or agitated * Having a lack of concentration or becoming easily distracted. * Becoming disorientated – not knowing where they are or what day it is. * Rambling speech. * Showing changes in behaviour. * Having disturbed patterns of sleeping and waking. * Being prone to rapid swings in emotion. * Experiencing hallucinations. * Having abnormal or paranoid beliefs.
