little bone mineral density brought on by changed bone microstructure is known as osteoporosis, which ultimately predisposes individuals to fragility fractures with little force. The quality of life is significantly reduced as a result of osteoporotic fractures, which also increase morbidity, mortality, and disability.
Soon, a presentation on the management of osteoporosis with physical therapy will be made available.
3. DEFINITION
• The most common metabolic bone disease.
• Osteoporosis is characterised by a diffuse reduction in the bone density due to decrease
in the bone mass.
• It occurs when the rate of bone resorption exceeds the rate of bone formation.
• The reduction of bone mass results in fragile skeleton associated with increased risk of
fractures and consequent pain and deformity.

6. PATHOPHYSIOLOGY
• Bone loss due to normal age related changes in bone remodelling as well as extrinsic and intrinsic factor that
exaggerated this process.
• Bone remodelling has two primary functions
1. To repair micro damage within the skeleton to maintain the skeletal strength.
2. To supply calcium to maintain calcium supply.
• After age 30- 40, the resorption and formation processes becomes imbalanced and resorption exceed
formation.
• Excessive bone loss can be loss due to an increase in osteoclastic activity and/or osteoblastic activity.
9. PRIMARY OSTEOPOROSIS
• Primary osteoporosis results without an underlying disease or medication
• It is further divided into 2 types: 1. Idiopathic type
2.Involutional type
• Idiopathic type is found in the young and juveniles and is less frequent.
• Involutional type is seen in postmenopausal women and ageing individuals and is more
common.
• In women, there is an accelerated phase of bone loss after the menopause due to
estrogen deficiency, which causes uncoupling of bone resorption and bone
formation, such that the amount of bone removed by osteoclasts exceeds the rate of
new bone formation by osteoblasts.
10. SECONDARY OSTEOPOROSIS
• It is attributed to number of factors and conditions.
• E.g : Immobilization, chronic anaemia, acromegaly, hepatic diseases,
hyperparathyroidism, hypogonadism and starvation.
• This can be an effect of medication.
• E.g : hypercortisonism, administration of anticonvulsants drugs and large dose of
heparin.
11. CAUSES
• Senility
• Post-immobilization e.g a bed ridden
patient
• Post-menopausal
• Protein deficiency
inadequate intake- old age, illness
malnutrition
excess protein loss (3rd degree burns)
mal-absorption
• Endocrinal :
Cushing’s disease
Hyperthyroid stage
• Drug induced:
Long term steroid therapy
phenobarbitone therapy
Chronic heparin therapy
• Rheumatological conditions :
RA
Ankylosing spondylosis
12. • Lack of calcium diet
• Lack of physical activity
• Family history
• Smoking
• Chronic obstructive pulmonary disorders
• Asthma
• Gastrointestinal diseases
13. CLINICAL FEATURES
• Asymptomatic until fracture occurs
• Fractures due to bone fragility are the most
common manifestations.
• Back pain
• Height loss
• Increased Kyphosis
• Decreased activity tolerance
• Osteoporotic fractures can affect any bone,
but the most common sites are the forearm
(Colle’s fracture), spine (vertebral fracture)
and hip. Of these, hip fractures are the most
serious.
• Immobility
• Loss of height
14. INVESTIGATIONS
1. X-RAY :
• In severe cases , a spine or hip x-ray may
show fracture or collapse of the spinal bones
• However , simple x-rays of bones are not
very accurate in predicting whether someone
is likely to have osteoporosis.
16. 2. CT-SCAN :
• A special type of spine CT that can show loss
of bone mineral density, quantitative
computed tomography (QCT) may be used in
rare cases.
17. 3. DEXA (DEXA ENERGY XRAY
ABSORBTIOMETRY):
• A bone density is a low dose x-ray which
checks an area of the body such as the hip,
hand or foot for signs of mineral loss and
bone thinning
18. 4.NEUTRON ACTIVATION ANALYSIS:
In this method , calcium in the bone is activated
by neutron bombing , and its activity measured,
5. BONE BIOPSY
19. DIAGNOSTIC FEATURES
A medical evaluation to diagnose osteoporosis and estimate risk of breaking a bone may involve
one or more following steps:
1. Medical history
2. Physical examination
3. Bone density test
4. Laboratory test
20. ICF
1. Structures related to the nervous system
2. Structures related to eye, ear , voice and speech
3. Structures related to cardiovascular , immunological and respiratory systems.
4. Structures related to the digestive , metabolism and endocrine system.
5. Structures related to genito-urinal and reproductive system.
• STRUCTURAL INTEGRITY
21. • STRUCTURAL IMPAIRMENT:
IMPAIRMENT
1. Deterioration of bone tissue
2. Increased porosity of bone
3. Bone fractures
4. Increased bone fragility
5. Decreased bone mass
6. Increased bone resorption
CLINICAL REASONING
Reduced bone mineral density
Decreased Cortical thickness and
no. & size of trabeculae
Increased porosity or trauma
Low bone mass
Insufficient dietary intake of
calcium, phosphorus, Mg , vit D
Increased no. of osteoclasts

CLINICAL REASONING
Abnormal stress on the spinal
muscles & ligaments
Due to reduced intrathoracic
volume or early satiety due to the
compression of the abdominal
cavity as the rib cage approaches
the pelvis
Weakening of the bones
Weakness of spine muscles
