Bone & Joint Health
Osteoporosis isn't just a women's disease—men have higher mortality after hip fracture. Joint degeneration isn't inevitable. Here's what actually preserves mobility.

Men think osteoporosis is a women's disease—until they break a hip. One-third of hip fractures occur in men, and men have 37% higher 1-year mortality after hip fracture than women. Joint degeneration (osteoarthritis) affects over 32 million Americans. Both conditions are undertreated in men because they're under-recognized.
The mortality gap is staggering. Men are twice as likely to die within a year of a hip fracture compared to women. This is partly because men present with more comorbidities and more advanced disease—because they weren't screened or treated earlier.

⚠️ Risk Factors in Men
- Age >70: Primary risk factor; screening recommended
- Low testosterone/hypogonadism: Major cause in men
- Glucocorticoid use: >3 months prednisone equivalent
- Smoking: Directly toxic to bone cells
- Heavy alcohol use: >3 drinks/day
- Low BMI (<20): Less mechanical loading
- Prior fragility fracture: Strongest predictor of future fracture
- Family history: Hip fracture in parent
🔬 Secondary Causes to Rule Out
- Hypogonadism: Check testosterone
- Vitamin D deficiency: Very common, treatable
- Hyperthyroidism: Accelerates bone loss
- Hyperparathyroidism: Check calcium and PTH
- Multiple myeloma: If unexplained in younger men
- Celiac disease: Malabsorption of calcium/vitamin D
- Medications: PPIs, anticonvulsants, androgen deprivation
| DEXA T-Score | Classification | 10-Year Hip Fracture Risk | Action |
|---|---|---|---|
| ≥-1.0 | Normal | ~1% | Lifestyle measures |
| -1.0 to -2.5 | Osteopenia | 2-5% | Consider FRAX; lifestyle + monitor |
| ≤-2.5 | Osteoporosis | 5-15% | Treatment usually indicated |
| ≤-2.5 + fracture | Severe osteoporosis | >15% | Treatment definitely indicated |
Fracture Prevention
🛡️ Bone-Building Strategies
- Resistance training: Mechanical loading stimulates bone formation
- Weight-bearing exercise: Walking, jogging, stairs, tennis
- Calcium: 1000-1200mg/day (food preferred over supplements)
- Vitamin D: 800-2000 IU/day; test if risk factors
- Protein: Adequate intake supports bone matrix
- Quit smoking: Smoking impairs bone healing
- Limit alcohol: ≤2 drinks/day
💊 Treatment Options
- Bisphosphonates: First-line; alendronate, risedronate, zoledronic acid
- Denosumab: Every 6 months injection; don't stop abruptly
- Teriparatide: Anabolic; for severe osteoporosis
- Romosozumab: Anabolic then antiresorptive; high risk patients
- Testosterone: If hypogonadal (not first-line for bone alone)
Exercise is underrated for bone health. Resistance training and weight-bearing exercise stimulate bone formation through mechanotransduction. Even in older adults with osteoporosis, appropriate exercise reduces fracture risk more than it increases it.
Joint Health & Osteoarthritis
Osteoarthritis (OA) affects ~32 million Americans. It's not just "wear and tear"—it's a complex process involving cartilage breakdown, inflammation, and bone remodeling. But it's more modifiable than people think.

🔬 What's Actually Happening
- Cartilage degradation: Matrix metalloproteinases break down collagen
- Inflammation: Synovitis drives symptoms and progression
- Bone changes: Subchondral sclerosis, osteophytes
- Muscle weakness: Quadriceps weakness accelerates knee OA
- Obesity: Mechanical stress + adipokine inflammation
- Metabolic factors: Diabetes and metabolic syndrome worsen OA
💪 What Actually Helps
- Exercise: Counterintuitively, movement helps joints
- Weight loss: Every 1 lb lost = 4 lb less knee load
- Strength training: Supporting muscles protect joints
- Physical therapy: Targeted exercise, manual therapy
- NSAIDs: Short-term relief; not for chronic use
- Acetaminophen: Safer but less effective than NSAIDs
- Injections: Corticosteroids (short-term); hyaluronic acid (variable)
Movement is medicine for joints. Cartilage has no blood supply—it gets nutrition from synovial fluid, which circulates with movement. Prolonged rest makes OA worse, not better. The key is appropriate exercise, not avoidance.
| Supplement | Evidence | Notes |
|---|---|---|
| Glucosamine | Mixed/Weak | Large trials (GAIT) showed minimal benefit over placebo |
| Chondroitin | Mixed/Weak | Similar to glucosamine; may have small benefit |
| Collagen peptides | Preliminary | Some promising data; needs more research |
| Turmeric/Curcumin | Moderate | Anti-inflammatory; bioavailability is an issue |
| Fish oil (Omega-3) | Moderate | Reduces inflammation; may help symptoms |
✓ Your Bone & Joint Action Plan
✓ Get DEXA scan if over 70 or with risk factors
✓ Resistance train 2-3x weekly (loads bone and protects joints)
✓ Get calcium 1000-1200mg/day from food if possible
✓ Ensure vitamin D adequacy (test if unsure; supplement 800-2000 IU)
✓ If joint pain, keep moving—don't rest excessively
✓ Maintain healthy weight (every lb matters for knees)
✓ Strengthen muscles around problem joints
✓ Quit smoking; limit alcohol to ≤2 drinks/day
📌 The Bottom Line
Get Screened
Men are under-screened for osteoporosis. DEXA at 70, or earlier with risk factors.
Lift Weights
Resistance training is the best intervention for both bone density and joint protection.
Keep Moving
Rest doesn't help arthritis. Movement lubricates and nourishes cartilage.
Lose Weight If Needed
Every pound lost is 4 pounds less stress on your knees.
