Q

what contributes to the stability of the joint?

A

The acetabulum almost entirely encompasses the hemispherical head of the femur.
The lunar surface is covered by hyaline cartilage and is broadest superiorly

Q

What is the ligament of the head of the femur?

A

A flat band of delicate connective tissue that attaches at one end to the fovea of the head of the femur and at the other end to the acetabular fossa. It carries a small branch of the obturator artery, which contributes to the blood supply of the head of the femur.

Q

How are the fibres of these ligaments orientated?

A

in a spiral fashion around the hip so that they become taught when the hip is extended
this stabilises the joint and reduces the amount of energy required to maintain standing

immediately mopping up spillages
remove clutter, trailing wires, frayed carpet
use non-slip mats and rugs
high wattage lamps
organise home so climbing, stretching and bending are minimised
get help to do things that aren’t safe
don’t wear loose fitting, trailing clothes
wear well fitting shoes that support the ankles
foot care
strength and balance training
sight tests
home hazard assessment
personal alarms
alcohol

25
what are the surgical options for repairing a hip fracture?
internal fixation can be performed with multiple pins inter medullary hip screws cross screw-nails or compression with a dynamic screw or plate replacing the femoral head is achieved either by hemioarthroplasty and total hip replacement
26
What is the general rule for deciding what surgical options to take for hip fractures?
internal fixation is recommended for young, otherwise hip patients at low risk of AVN prosthetic replacement is reserved for the elderly and for fractures with a high risk of AVN
27
What are common surgical complications in the elderly?
infection DVTs pressure ulcers
28
What is involved in the rehabilitation from hip surgery?
physiotherapists occupational therapists weight bearing exercises strength and balance training
29
What is the normal percentages of bone and muscle in young adults?
bones - 15% | Muscle 30-40%
30
What is the rate of muscle and bone turnover in young adults?
20%
31
what does the mass of muscle and bone reflect?
a couple interaction of mechanical demand, dietary, genetic and endocrine factors
32
What do remodelling processes rely on?
sufficient nutrients and a balance of parathyroid hormone,calcitonin and vitamin D
33
What is the homeostatic balance of bone remodelling disturbed by?
``` diet and lifestyle (rickets) mechanical factors (disuse) endocrine disorders ```
34
What are the physiological consequences of a prolonged space flight?
``` fluid shifts negative energy balance skeletal and cardiac muscle atrophy bone mineral degradation radiation exposure ```
35
what are the consequences of suboptimal energy intake?
increased protein turnover decreased weight and muscle mass decreased muscle protein synthesis
36
In what way is the world's population growing?
exponentially
37
what is the current rate of population growth?
1.13%
38
When will the world's population have doubled by?
62 years
39
What determines the growth or decline of populations?
births deaths migration
40
what are demographics?
the scientific study of human populations especially with reference to their size, structure and distribution
41
what is a demographic transition?
transition from high birth and death rates as a country develops from pre-industrial to an industrialised economic system
42
what is epidemiology?
the science and practise which describes and explains disease patterns in populations
43
what are epidemiological transitions?
long term shift in the pattern of disease in a country from infectious disease to degenerative disease
44
What is meant by an ageing population?
it is a global phenomenon occurring based in low and middle income countries. In scotland older people form an increasingly large part of our population
45
What does an ageing society have impacts on?
implications for the old-age dependency ratio (the ratio of people over 65 years in the population to the size of the economically active segment of the population
46
what is compression of mortality?
a greater proportion of deaths occur during a narrow time period at the upper limit of a human life span
47
What is compression of morbidity?
optimistic scenario which increasing proportion of population will live a ling, healthy life in which death will be preceded by a very short period of ill-health
48
what are incidence rates?
the number of new events occurring in a specific time in a defined population
49
what is prevalence?
the number of cases of disease or other health outcome present in a specific period of time in a defined population.
50
What is ageing associated with?
progressive, generalised impairment of functioning resulting in a loss of adaptive response; lung function, circulation, muscles, nerves, immune system etc
51
What have impacts on the rate of ageing?
genetic component social determinants of health slow/ step wise decline
52
how is health measured?
functional status activities in daily life well being
53
Wear is quality of life?
the satisfaction of an individual's values, goals and needs through the actualisation of their abilities or lifestyles
54
According to WHO what needs to be considered in quality of life?
``` physical environmental social relationships level of dependence spiritual ```
55
What effects can muscle-skeletal diseases have on people's health?
``` leading cause of chronic morbidity severe long term pain long term active limitation sleep disturbance exacerbate symptoms of anxiety and depression accessibility problems social interactions drug side effects ```
56
What is a QAly?
``` a year of full quality life age context content specific long-term care reliability and validity ```
57
What are examples of early interventions to improve the quality of life of older people?
older people at the heart of the community understand the plan for the needs of older people value their contribution to society provide good affordable health care
58
What is the scottish government aiming for to improve the health of older people?
contribution of older people is valued age is not used to define or make assumptions people with more years of healthy life and are able to manage long term conditions people are entitled to work, in a way that suits them older people have access to IT and internet
59
What are the main functions of the musculoskeletal system?
enables efficient limb movement acts as protection serves as reservoir for calcium provides environment for marrow
60
What occurs in bone ageing?
reduced bone tissue, relative decline in trophic factors favouring osteoclastic activity. diminished differentiation of bone marrow stem cells
61
What occurs in chondroid tissue ageing?
reduced ability to form large hydrophilic complexes resulting in decreased swelling pressure, predisposing to OA and IVD degradation
62
What occurs in the ageing of ligaments?
altered collagen synthesis leading to reduced elasticity
63
what happens as muscles age?
loss of muscle mass and decreased power due to loss of fibre number and fibre atrophy
64
What is sarcopenia?
a syndrome associated by progressive and generalised loss of skeletal muscle mass and strength associated with ageing, with risk of adverse outcomes such as physical disability, poor quality of life and death
65
what are factors which affect sarcopenia?
``` age activity disease nutrition lack of exercise endocrine neurodegenerative disease cachexia disuse ```
66
What are consequences of MSK ageing?
altered gait and balance leading to falls or fear of falls increased risk of injury - fractures chronic pain social isolation if living independently admission to care home
