Osteoporosis is a condition that can silently weaken your bones, often without you even knowing, until that unexpected fracture occurs. This is why we often call it the “Silent Disease”; it may only be detected after a fracture from a minor fall.
In my years as an orthopedic doctor here in Chennai, I've seen firsthand how devastating this can be. That's why I always stress to my patients the absolute importance of early detection and proactive management. It’s our best defense against the heightened risk of fractures that osteoporosis brings.
Fractures occur because osteoporosis disrupts how your bones naturally rebuild, leading to excessive tissue loss. Consequently, even simple movements can cause fractures.
In this article, I want to share my insights on how osteoporosis increases fracture risk and why understanding it is vital for effective fracture management.
What is Osteoporosis?
Osteoporosis is a condition characterised by low bone density and deterioration of bone tissue. It increases the risk of fractures, leading to pain, disability, and decreased quality of life. While medications and other treatment options are available, exercise plays a crucial role in managing osteoporosis and reducing fracture risk.
How Osteoporosis Increases Fracture Risk by Weakening Bones
Here’s how osteoporosis increases fracture risk. This condition doesn't merely cause fragile bones. It reduces bone density and causes significant structural damage to your bone architecture. This dangerous combination compromises your bone strength, making fractures disturbingly common even from simple movements.
Naturally, your bones remain strong thanks to bone remodelling. Osteoclasts, a type of bone cell, remove ageing bone tissue while osteoblasts rebuild it anew. In people with good health, this system balances bone breakdown with bone formation/building like a fastidious demolition-and-construction crew working to preserve your body's frame.
But osteoporosis disrupts this equilibrium. Osteoclasts start demolishing bone tissue much faster than osteoblasts can reconstruct it. Here’s what happens:
- First consequence: The dense outer armour (cortical bone) undergoes significant thinning, like weather-beaten steel losing its protective plating, leaving your bone increasingly defenceless against impacts.
- Double blow: The honeycomb-like trabecular bone inside deteriorates. This intricate bone architecture becomes sparse and disconnected, resembling scattered toothpicks rather than sturdy, interconnected support beams.
Combined, these structural failures result in bone loss far more damaging than simple thinning. Imagine holding a solid steel bar compared to one riddled with internal corrosion—same external shape, but dangerously weaker.
Common Fractures Associated With Osteoporosis
Having explored the hidden dangers of weakened bone structure and compromised bone architecture, let's uncover why osteoporosis targets specific zones. While the entire skeleton feels the strain of reduced bone strength, three areas become prime candidates for fractures when bones lose their density and structural soundness:
1. Spine
2. Hips
3. Wrists
These parts of your body carry the highest risks. This vulnerability stems from factors like their weight-bearing roles and bone composition, making them susceptible when structural compromise sets in.
Three critical types of these fractures and their consequences emerge:
1. Spinal compression fractures
Spinal compression fractures compromise your height and posture. Simple actions like lifting groceries or even a sudden sneeze can crumple weakened spinal vertebrae like empty eggshells. These silent collapses cause:
- Gradual but visible height loss
- The signature “stoop” associated with osteoporosis
- Persistent low back pain
2. Hip fractures
While falls often trigger these breaks, their effects extend far beyond the hospital bed. A broken hip can lead directly to:
- Emergency surgery and lengthy rehabilitation
- Significant loss of independent living
- An alarming increase in mortality risk
3. Wrist fractures
Falling forward triggers a natural reaction—palms out to soften the impact. With brittle bones in the wrist area, what was protective becomes sacrificial, resulting in a fracture.
Recognising these particular fracture mechanisms illustrates how weakened bones enable minor accidents/incidents to become life-altering situations. Now, let's take a look at the risk factors that can hasten this decline in bone function.

Who is Most at Risk of Osteoporosis?
Osteoporosis is a degenerative disease involving the gradual decline of bone strength and density. Given below are some of the main contributors that increase the chances of developing osteoporosis:
- Ageing: Causes bones to become brittle and more prone to fractures.
- Genetic predisposition: Individuals with a family history of osteoporosis are likely to develop this condition as they age.
- Sex: Women are more prone to osteoporosis than men, the main reason being the drastic drop in oestrogen levels after menopause, which is vital for bone strength.
- Personal habits: Regular smoking, alcohol intake, sedentary lifestyle, and a poor diet can impact your bone health.
- Medication intake: Long-term use of medications like corticosteroids for rheumatoid arthritis and coeliac disease can gradually weaken the bones.
Diagnosing Osteoporosis: The Role of DEXA Scans
Accurate diagnosis with a DEXA (Dual-Energy X-ray Absorptiometry) scan is the best way to determine your risk for osteoporosis-related fractures. The DEXA scan is a painless, non-invasive imaging technique considered the gold standard for measuring Bone Mineral Density (BMD). Here’s how it works:
- The scan measures the bone density in your spinal area, hips, and wrists—the three key areas prone to osteoporotic fractures.
- It creates a T-score, which compares your bone mass to that of a healthy young adult.
- It also delivers a Z-score, which compares your bone mass with someone your age and gender.
These scores provide a clear indication of your current bone density and strength.
Apart from the DEXA scan, your doctor may suggest the following methods to determine bone density:
-
CT scan
A CT scan is recommended to measure bone density, particularly in the spine. It also takes detailed images of the fracture-prone areas.
-
Spine and hip X-rays
X-rays of the spine and hip help identify fractures that occur due to osteoporosis.
-
Heel ultrasound
This diagnostic method measures bone density in the heel with the help of sound waves. The equipment is cost-effective and portable. However, it does not deliver accurate results like the DEXA scan.
This early detection/screening and diagnosis of osteoporosis presents you with a large window of opportunity to take proactive steps to keep your bones safe from damage and reduce the risk of fractures.
Strategies to Reduce Fracture Risk With Osteoporosis
While we discussed how ageing naturally (unavoidably) makes the bones weaker, a number of definite factors sharply increase your vulnerability to osteoporosis and fractures—some unavoidable, yet some controllable with wise choices. View the following as silent cofactors/strategies in improving bone health:
-
Prioritise a bone-healthy diet for bone health
Include calcium-rich foods such as dairy, fortified foods, and leafy vegetables. Add vitamin D-rich supplements and take sunlight exposure regularly.
-
Take up a routine workout or sports activities
Regular exercise is a blessing for your bones. Weight training, dancing, brisk walking, tai chi, and yoga strengthen your bones enough to escape the risk of osteoporotic fractures.
-
Modify your lifestyle and habits
Quit smoking and limit your alcohol intake. These habits can compromise/weaken your bone strength and make you prone to osteoporosis.
-
Follow your medications
Your doctor may prescribe medications to help rebuild bones or slow down the effects of osteoporosis on your bones. It is essential to follow the prescribed dosage until your doctor gives further instructions.
-
Make your surroundings risk-free
Ensure your home and work surroundings are free of any hazards that increase your risk of falls by:
- Organising your furniture
- Removing loose rugs
- Installing grab bars in restrooms and shower stalls

FAQs: A Closer Look Into Osteoporosis & the Increased Risk of Fractures
1. What are the symptoms of an impending osteoporotic fracture?
Osteoporosis is called the silent disease because it rarely manifests until a fracture occurs. While a DEXA scan is the best way to test your bone density and determine the likelihood of fractures, you can also expect early indications such as:
- Gradual loss of height
- Brittle nails
- A hunched or stooped posture
- Constant back pain
2. What is the role of a DEXA scan in osteoporosis diagnosis?
The DEXA scan measures bone mineral density in the three major risk-prone areas of the body:
1. Spine
2. Hips
3. Wrists
The scan’s T-scores and Z-scores help determine your fracture risk and facilitate further treatment plans.
3. Can osteoporosis-related fractures heal like regular fractures?
Osteoporotic fractures may require a longer time to heal, especially in older adults. Pelvic and hip fractures may sometimes require surgery, physiotherapy, and lifestyle modifications to facilitate healing, mobility, and range of motion.
4. Can osteoporosis occur in men, or is it confined to women?
Osteoporosis is common to both sexes, although menopausal women are more likely to develop this condition. In men, the risk increases for those with the following risk factors:
- Low levels of testosterone
- Chronic illnesses
- Intake of certain medications
Osteoporosis in men is often underdiagnosed. Hence, awareness of the risk factors is crucial.
5. What type of exercises help prevent osteoporosis-related fractures?
The following exercise regimes help build and maintain bone density:
- Strength training
- Weight-bearing exercises
- Balance training workouts
- Brisk walking
- Climbing stairs
- Resistance training
