Block 43 Flashcards
List the 7 criteria which classify a baby as ‘at risk’ of DDH, warranting a referral for US scan.
1) All babies born breech from 36 weeks onwards, breech births (vaginal or caesarean) including those where ECV was carried out.
2) FHx of hip dysplasia or dislocation.
3) Congenital deformity the feet.
4) Clicky hips
5) Unstable hips
6) Limited abduction in flexion.
7) Apparent shortening of one/ both legs.
Why can the use of USS to screen for DDH lead to over treatment?
Because USS for DDH has a high sensitivity but a low specificity.
1) Pathological DDH is mainly associated with which sex?
2) Describe the PPV of the 6-8 week GP hip check for DDH.
3) What is a useful clinical sign in diagnosis of pathological DDH?
1) Pathological DDH is mainly a female condition.
2) GP 6-8 week hip check has a very low PPV for pathological DDH.
3) Unilateral limitation of hip abduction.
Give 3 ways in which abnormal gait/ posture can socially impact upon a patient and they family.
1) Only a small proportion of these abnormalities are clinically significant, but they can cause much parental anxiety.
2) Child may get stigmatised/ bullied for different gait or posture.
3) May become socially withdrawn.
Give 3 psychological/ socioeconomic consequences of hip fractures for patients, their families or the wider community.
1) Injury can cause massive change in lifestyle (previously dependent elderly patient may become dependent and require carers).
2) An elderly person suddenly becoming much less independent may lead to social isolation and subsequently depression.
3) In a young person, may mean an inability to get back to playing sports which may lead to depression.
4) 30% mortality within a year.
5) Hip fractures cost NHS £2billion annually.
Name 5 risk factors for osteoporosis.
1) Female
2) CKD
3) GI disease/ poor calcium intake
4) Oestrogen deficiency (i.e. menopause)
5) Hyperparathyroidism
6) Increased age
7) Decreased BMI
8) Smoking and alcohol intake
Name 3 drugs which can increase the risk of developing osteoporosis.
1) Glucocorticoids
2) Aromatase inhibitors
3) SERMs
4) Anti-androgens
5) PPIs
6) SSRIs
According to NICE, which patients may need a falls assessment?
Those aged over 65 who:
1) have had one or more falls in the last 12/12
2) are at risk due to:
- cognitive/ visual impairment
- frailty/ a condition which affects balance (PD, arthritis, stroke)
- taking multiple/ psychoactive/ anti-hypertensive drugs
State 2 tests which can be done to assess a patient’s falls risk.
1) ‘Time up and go test’ = patient is timed to get up and out of a chair, walk 3m and then return to the chair. 12-14s = increased risk of fall.
2) 180 degree turn test = ask patient to stand and turn 180 degrees about the spot. If this requires more than 4 steps, there is an increased falls risk.
State 5 factors that a multifactorial falls assessment might assess.
1) identification of falls history
2) assessment of gait, balance and mobility, and muscle weakness
3) assessment of osteoporosis risk
4) assessment of the older person’s perceived functional ability and fear relating to falling
5) assessment of visual impairment
6) assessment of cognitive impairment and neurological examination
7) assessment of urinary incontinence
8) assessment of home hazards
9) cardiovascular examination and medication review
1) What percentage of the community aged over 65 have a fall each year?
2) What percentage of the community aged over 65 who have experienced at least one fall then have recurrent falls each year?
3) How much more common are falls in institutions compared to in the community?
4) What percentage of those in the community aged over 90 have a fall each year?
1) 30%
2) 50%
3) 3x more common
4) 55% of those over 90 will have a fall each year
1) What are the most common cause of injury in the elderly?
2) What percentage of falls cause a hip fracture?
1) Falls
2) 1-2% falls cause a hip fracture.
Name 3 consequences of an elderly person having a fall or recurrent falls.
1) Hip fracture (50% no longer live independently after this)
2) Minor injuries (cuts, contusions)
3) ‘Long lie’ leading to hypothermia, pressure sores, pneumonia, rhabdomyolysis, AKI, CKD.
4) Psychological problems (fear of falling, self-imposed activity restriction, loss of mobility, depression)
**note that there are also impacts on carers as the patient often is increasingly dependent and more disabled.
Clinically, describe the presentation of a hip fracture.
Characteristically externally rotated and shortened.
**NOF fracture may impinge blood supply to femoral head, leading to avascular necrosis.
State the 4 ways in which outcome from hip fractures can be improved.
1) Fast admission.
2) Operate within 24 hours.
3) Mobilise within 24 hours.
4) Initiate early discharge planning with carers.
If a patient performs poorly in the ‘time up and go’ and ‘180 degrees turn test’, what might be offered?
A multifactorial falls assessment.
Describe 2 ways in which hip fractures can be prevented.
1) Falls prevention
2) Bone protection (bisphosphonates, calcium/ vitamin D supplements, HRT)
1) Describe the effect of calcium/vitamin D supplements on preventing hip fractures)
2) Why do bisphosphonates often have poor compliance?
3) What are the risks of taking HRT?
4) By what percentage do bisphosphonates decrease hip fracture occurrence?
5) By what percentage does HRT decrease hip fracture occurrence?
1) Calcium and vitamin D have a modest effect when used in combination but vitamin D does not have an effect when used in isolation.
2) Because daily use causes gastric SEs.
3) Increased risk of DVT, breast cancer and dementia.
4) 30%
5) 20-30%
Name 5 risk factors for hip fractures.
1) Increasing age (every 5yrs = 2x increased risk)
2) Female
3) Low BMI
4) Smoking
5) PMHx of fractures
6) FHx of fractures
7) Corticosteroid use
8) Ethnicity (Afrocaribbean = decreased risk)
State 3 risk factors for falling along with their relative risk of causing a fall.
1) Muscle weakness (RR - 4.4)
2) Fall Hx (RR - 3)
3) Gait + balance deficit (RR - 2.9)
4) Visual deficit (RR - 2.5)
**Risk varies for different visual problems (depth perception > contrast sensitivity > acuity).
Is polypharmacy a risk factor for falls?
It is thought that the risk of fall due to chronic disease and multiple pathologies is higher than the polypharmacy needed to control these.
Give 3 ways that Tinetti suggested falls risk can be reduced.
1) Psychotropic drug withdrawal (decreased falls by 66% but also decreased QoL)
2) OT assessment (assess at home risk and make recommendations to decrease risk)
3) Podiatry input (better footwear, orthotic devices, calf-ankle exercises)
What are the aims of rehabilitation after a fall causing injury?
Aims are to maximise independence, enable normal ADLs and to maintain social participation.
Briefly describe the rehab process following a hip fracture.
Following fracture, patients are referred to an MDT who will coordinate their rehabilitation care.
