With age comes wisdom………..
and Osteoporosis
What is osteoporosis ?
Normal Osteoprosis
Jargon buster………
• Softening of bones …….
• A reduction in the quantity and quality of
bones
What is osteoporosis
• A condition rather than a disease
• Silent until complications arise
• Spine, hip & wrist fractures
WHO criteria for diagnosis of
Osteoporosis
Kanis et al. J Bone Miner Res 1994; 9:1137-41
T-score
Normal - 1.0 and above
Osteopaenia - 1.0 to - 2.5
Osteoporosis - 2.5 and below
Severe (established)
osteoporosis
- 2.5 and below, plus one
or more osteoporotic
fracture(s)
Food for thought…..
1. Osteoporosis ≠ Calcium deficiency
• So, calcium is NOT the treatment of
osteoporosis
• Bone mineral v/s bone mass
2. Osteoporosis is a generalized disease
• affects all the bones
3. Treating osteoporosis
• Prevention is the only treatment of
osteoporosis
• Hence early diagnosis is the most important
step in treating osteoporosis !
Size of the Problem in India
• 26 million (2003) 36 million by 2013
• 1 out of 8 males and 1 out of 3 females suffers from osteoporosis
• The high incidence among men and the lower age of peak incidence
compared to Western countries
• Peak incidence of osteoporosis
– Western countries-70-80 years of age
– India –50-60 years
International Osteoporosis Foundation
The Magnitude Of The Problem
In women > 50 years, the lifetime risk of:
• Vertebral fracture is 1/3
• Hip fracture is 1/5

Osteoporosis affects entire skeleton
• Osteoporosis is responsible for >1.5 million vertebral and
non-vertebral fractures per year
• Spine, hip, and wrist fractures are most common
Morbidity associated with Fractures
Osteoporosis: Classification
• Primary Osteoporosis
Type 1- Post menopausal osteoporosis
Type 2- Senile/Age related osteoporosis
• Secondary Osteoporosis
Secondary to various causes

Consequences
Reduced quality of life
How is osteoporosis diagnosed
Diagnosis is made on the basis of-
• Detailed medical history
• Examination
• Blood and other tests
Early diagnosis of Osteoporosis
• Clinical parameters
– ‘at risk’ subject
– Bone pains
– Generalized tiredness
– Progressive kyphosis
• Investigations
– Radiographs
– DEXA
– QCT, MRI, Bone scan
– Blood markers
Clinical Risk Fractures (CRF)
Predictors of low bone mass-
• Female
• Advanced age
• Low bone mineral density
• Gonadal hormone deficiency ( estrogen or testosterone )
• White race
• Low body weight & BMI
• Family history of osteoporosis
• Low calcium intake
• Smoking / excessive alcohol intake
• Low level of physical activity
• Chronic glucocorticoid use
• Prior fragility fracture
National Osteoporosis Foundation (NOF)
Clinical Presentation
• Severe backache after minor injury
• Pain worse on sneezing, coughing , standing
erect, changing positions.
• Limited to wheelchair
• Stooped Posture
• Weakness in legs
X-rays
• Osteopenia
• Loss of height of vertebral
body
• Wedging
Osteoporosis – RadiographicOsteoporosis – Radiographic
Differential DiagnosisDifferential Diagnosis
• Osteomalacia
• Hyperparathyroidism
• Hypercortisolism
• Hyperthyroidism
• Renal insufficiency
• Chronic immobilization
• Osteogenesis imperfecta
• Hepatic insufficiency
• Diabetes mellitus
• Multiple myeloma
• Metastatic disease
• Drug induced
Osteoporosis other causesOsteoporosis other causes
Assessment of bone mineral density by DXA
Current gold standard for diagnosis of osteoporosis
BMD (g/cm2
) = Bone mineral content (g) / area (cm2
)
Diagnosis based on comparing patient’s
BMD to that of young, healthy individuals
of same sex
• Blood count , CRP
• Calcium, Phosphate, Alkaline
Phosphatase (AP)
• Kidney function studies
• Basal Thyroid and parathyroid.
• Protein-immunoelectrophoresis.
• Vit D (25 and 1.25)
Laboratory tests*
NOTES:
- * These are in addition
to routine labs tests.
- These are screening
labs, more may be
indicated based on these

How much and which Calcium??
• 1000-1500mg “elemental calcium”
Type of calcium Elemental Calcium
Calcium carbonate 40%
Calcium gluconate 9%
Calcium lactate 13%
Calcium citrate 20-30%
Calcium acetate 30%
Micro cryst HA complex 100%
◦ May be difficult to attain those levels.
◦ To try a combination of diet and medicines
◦ Can’t give more than 500mg elemental calcium as tabs at a single dose
Bisphoshonates
• Etidronate, Alendronate, Risendronate,
Ibandronate, Zolendronate
– Anti resorptive agents
– Reduce osteoclasis
Bisphoshonates
• Induce apoptosis (self destruction) in the osteoclasts
• Thus it reduces bone resorption
Bisphoshonates
• On this ‘preserved’ lattice – mineralization takes
place
• Thus ‘better mineralized’ bone is formed and
DEXA improves
Teriparatide (PTH)
• In small / pulse doses, is a powerful stimulant for
bone formation
• The only drug that can induce osteogenesis
Teriparatide
• Teriparatide stimulates formation of new bone
matrix / framework
Teriparatide
• On this denser, better structured matrix,
mineralization takes place giving rise to an
overall stronger bone

Editor's Notes

  • #31 Treatment and prevention (7) One of the most important preventive strategies is to encourage the achievement of optimal peak bone mass in the young, since this has a major impact on bone mass and the risk of osteoporosis after the menopause. Although peak bone mass is largely determined by genetics and diet (calcium and vitamin D intake), it can also be influenced by physical activity, smoking and alcohol consumption. It is, therefore, important to encourage both children and adolescents to adopt a healthy lifestyle.
  • #34 Treatment and prevention (8) For those patients at particularly high risk of osteoporosis, or who have developed osteoporosis, there are a number of pharmacological interventions available for the prevention and management of osteoporosis. The aim of these interventions should be to reduce the frequency of fractures, which are responsible for the high levels of morbidity associated with the disease.
