Osteoporosis is frequently described as a silent disease — bone loss progresses steadily, without pain or visible warning signs, until a fracture makes the condition impossible to ignore. In the United States, more than 10 million people are affected, and an estimated 44 million more have low bone mass that places them at elevated risk. Hip fractures carry particularly severe consequences for older adults, including prolonged hospitalization, loss of independence, and measurably higher mortality risk in the year following injury.
Early detection, accurate risk stratification, and a personalized prevention strategy can reduce fracture risk substantially — and in many cases prevent the first fracture from ever occurring. St. Alexius Medical Center, a regional health system within the CommonSpirit Health network, offers a structured, evidence-based approach to osteoporosis care that addresses prevention, diagnosis, treatment, and long-term monitoring as a coordinated continuum. This article outlines its core components: bone density screening, fracture risk assessment, and the prevention strategies that form the foundation of lasting bone health.
Understanding Osteoporosis: The Case for Proactive Care
Bone is living tissue, continuously rebuilding through a cycle of remodeling. New bone replaces old bone at a rate that favors formation during childhood and early adulthood, reaching peak bone mass typically in the late twenties. After that point, the balance shifts toward greater loss than gain. For postmenopausal women — due to the sharp decline in estrogen — this process can accelerate significantly in the years immediately following their last menstrual period.
Vertebral compression fractures cause chronic back pain and height loss; hip fractures frequently require surgery and extended rehabilitation; even wrist fractures, sometimes dismissed as minor injuries, often signal underlying skeletal fragility that predicts more severe events ahead. Catching bone loss before it reaches this point is the central goal of osteoporosis care.
Who Is at Highest Risk?
Certain populations carry a disproportionately high burden of osteoporosis and fracture. Recognizing these categories is the starting point for effective screening and prevention. The following groups are widely recognized by clinical guidelines as carrying elevated risk:
- Postmenopausal women, particularly those who experienced early or surgical menopause
- Adults over age 65, regardless of sex
- Individuals with a parent who experienced a hip fracture
- People with a personal history of any low-trauma fracture in adulthood
- Those receiving long-term corticosteroid therapy such as prednisone
- Individuals with low body weight or a history of disordered eating
- Current smokers and those with consistently high alcohol consumption
- People living with rheumatoid arthritis, celiac disease, hyperthyroidism, or other conditions linked to secondary bone loss
This list captures the most clinically significant risk categories, though other medications, lifestyle factors, and chronic diseases also play a role. Identifying where an individual falls within this landscape is the essential first step toward meaningful clinical intervention.
Bone Density Screening at St. Alexius Medical Center
Bone density screening is the diagnostic cornerstone of osteoporosis care. At St. Alexius Medical Center, the primary tool is dual-energy X-ray absorptiometry — universally referred to as a DEXA scan. This imaging technology uses low-dose X-rays to measure bone mineral density (BMD) at the hip and lumbar spine, the sites where osteoporotic fractures tend to be most consequential. The procedure is quick, non-invasive, and completed in under 30 minutes, with radiation exposure far lower than that of a standard chest X-ray.
Interpreting DEXA Results: Understanding the T-Score
DEXA results are expressed as a T-score — a comparison of the patient’s bone density to that of a healthy young adult at their peak bone mass. These T-score thresholds are standardized internationally and translate into the following clinical categories:
| T-Score Range | Bone Health Category | Clinical Significance |
|---|---|---|
| -1.0 and above | Normal | Bone density within the expected healthy range |
| Between -1.0 and -2.5 | Osteopenia (low bone mass) | Below-normal density; fracture risk is elevated but not at osteoporosis threshold |
| -2.5 and below | Osteoporosis | Significantly reduced density; high fracture risk; treatment typically warranted |
| -2.5 or lower with a prior fracture | Severe Osteoporosis | Highest risk category; immediate comprehensive intervention indicated |
These categories provide the clinical foundation for subsequent care decisions. T-scores are rarely interpreted in isolation, however — fracture history, age, and additional risk factors all shape how providers at St. Alexius Medical Center translate a DEXA result into an individualized treatment or monitoring plan.
Screening Recommendations and Scheduling
The clinical team at St. Alexius Medical Center aligns with guidance from the U.S. Preventive Services Task Force and the National Osteoporosis Foundation. The following represent widely accepted benchmarks for initiating screening:
- Women aged 65 and older: routine screening is universally recommended
- Women under 65 whose fracture risk equals or exceeds that of a 65-year-old white woman: earlier screening is appropriate
- Men aged 70 and older: screening is generally recommended
- Men aged 50 to 69 with risk factors such as low body weight, prior fracture, or corticosteroid use: screening should be discussed with a clinician
- Adults of any age who have experienced a fracture after minimal or no trauma: screening is strongly indicated
These benchmarks are starting points, not rigid rules. Individual health histories may prompt earlier or more frequent testing. The goal is to detect meaningful bone loss before it crosses the fracture threshold, when the most impactful preventive window is still available.
Fracture Risk Assessment: Beyond the Bone Density Score
A DEXA result provides essential data, but bone density alone does not tell the complete fracture story. Two patients with identical T-scores can carry very different fracture risks depending on age, fracture history, and other clinical variables. Comprehensive fracture risk assessment is a standard part of the diagnostic evaluation at St. Alexius Medical Center.
The FRAX Tool
The FRAX Fracture Risk Assessment Tool, developed by the World Health Organization Collaborating Centre for Metabolic Bone Diseases, calculates a patient’s 10-year probability of sustaining a major osteoporotic fracture — defined as a fracture of the hip, spine, wrist, or shoulder. It combines bone density data with a set of validated clinical variables that independently influence fracture risk. The inputs used by the FRAX algorithm include:
- Age and biological sex
- Body mass index (BMI)
- Personal history of adult fracture and parental history of hip fracture
- Current smoking status and alcohol consumption above three units per day
- Oral glucocorticoid use lasting three months or longer
- Presence of rheumatoid arthritis or other secondary causes of osteoporosis
- Femoral neck BMD from DEXA, when available
The resulting probability percentage is particularly useful for guiding treatment decisions in patients with osteopenia, where the case for pharmaceutical intervention is less automatic than at the osteoporosis threshold. CHI St. Alexius clinical teams interpret FRAX output within the context of a full clinical evaluation — never as a standalone decision tool.
Ruling Out Secondary Causes
A meaningful proportion of osteoporosis cases — especially in men and younger women — stem from identifiable underlying conditions rather than age-related or estrogen-deficiency-related bone loss. Common secondary contributors evaluated during a clinical workup at St. Alexius Medical Center include vitamin D deficiency, primary hyperparathyroidism, thyroid dysfunction, hypogonadism in men, celiac disease, and chronic kidney or liver disease. Laboratory testing for calcium, vitamin D, parathyroid hormone, and thyroid function is standard practice alongside DEXA imaging. Addressing a secondary driver is often a prerequisite to effective bone health management — overlooking it can result in persistent bone loss despite otherwise appropriate care.
Prevention Strategies: A Multifaceted Approach
CHI St. Alexius supports a prevention framework that combines nutrition, physical activity, fall risk reduction, and — when the clinical picture warrants it — pharmacological treatment. Each component plays a distinct role, and the most effective programs address all of them in a coordinated way.
Nutrition: Calcium and Vitamin D
Calcium and vitamin D form the nutritional foundation of bone health. Calcium is the primary mineral constituent of bone; vitamin D regulates its absorption and is essential for proper bone mineralization. Most adults need between 1,000 and 1,200 mg of calcium daily, ideally from food sources including dairy products, leafy greens, fortified plant-based milks, and canned fish with soft edible bones. Supplements can fill gaps when dietary intake falls short, with dosing spread throughout the day in amounts no greater than 500 mg at a time to support absorption. Vitamin D status is best confirmed by blood testing, with many adults requiring 1,000 to 2,000 IU of vitamin D3 daily, particularly in northern climates with limited winter sunlight.
Exercise: Building Strength and Preventing Falls
Physical activity serves a dual purpose: it stimulates bone formation through mechanical loading and reduces fall risk through improved strength and balance. The exercise types most protective for bone health include the following:
- Weight-bearing aerobic activity — walking, hiking, dancing, and stair climbing, most days of the week
- Resistance and strength training — weights, resistance bands, or bodyweight exercises targeting major muscle groups, two to three times weekly
- Balance and coordination training — tai chi, yoga, and single-leg exercises that measurably reduce fall frequency in older adults
- Postural strengthening — back extensor exercises to reduce kyphosis associated with vertebral fractures
For individuals already diagnosed with osteoporosis, exercise programming requires careful customization to avoid movements that place excessive load on compromised vertebrae or increase fall risk. Physical therapists at St. Alexius Medical Center develop individualized activity plans that balance bone-building benefit against injury risk at every stage of care.
Pharmacological Treatment When Needed
When lifestyle modification alone is insufficient — as determined by T-score, FRAX probability, or fracture history — medication becomes part of the clinical conversation. Several drug classes have demonstrated meaningful fracture risk reduction in clinical trials and are routinely considered within the St. Alexius Medical Center care setting:
| Drug Class | Representative Agents | Primary Mechanism | Typical Clinical Use |
|---|---|---|---|
| Bisphosphonates | Alendronate, risedronate, zoledronic acid | Reduces bone resorption by inhibiting osteoclast activity | First-line treatment for most patients |
| RANKL Inhibitors | Denosumab (Prolia) | Blocks osteoclast formation, slowing bone breakdown | Alternative for those unable to tolerate bisphosphonates |
| SERMs | Raloxifene | Mimics protective estrogen effects on bone tissue | Postmenopausal women, especially with spinal osteoporosis |
| Anabolic Agents | Teriparatide, romosozumab | Stimulates new bone formation | Severe osteoporosis or very high fracture risk |
Drug selection depends on fracture history, T-score severity, comorbidities, and patient preference. Treatment response is assessed through repeat DEXA scanning after one to two years, with laboratory monitoring tailored to the chosen agent.
The Multidisciplinary Care Model and Fall Prevention
Osteoporosis seldom exists in isolation. It frequently co-occurs with conditions such as rheumatoid arthritis, chronic kidney disease, and type 2 diabetes, and the medications used to manage those conditions can independently affect bone health. St. Alexius Medical Center addresses this complexity through a multidisciplinary care model involving endocrinologists, rheumatologists, orthopedic surgeons, physical therapists, registered dietitians, and primary care physicians — each contributing expertise to a coordinated plan. When one specialist identifies a new clinical concern, that information flows efficiently to the broader team.
Fall prevention is treated as an equally important pillar of fracture risk reduction. For a person with osteoporosis, a fall that causes nothing more than bruising in a healthy adult may produce a hip fracture requiring surgery. Strategies evaluated within the CHI St. Alexius program include home safety modifications, vision correction, medication reviews targeting sedating agents, and supervised balance training. For older adults with documented fall history or functional decline, a formal fall risk assessment is integrated into the bone health evaluation from the outset.
Conclusion: Starting the Conversation Early
Osteoporosis is preventable, detectable, and treatable — but it responds best to deliberate, early action. Waiting for a fracture to prompt evaluation is a missed opportunity to intervene at a far less damaging stage. Through DEXA-based screening, validated fracture risk tools like FRAX, and individualized prevention strategies spanning nutrition, exercise, and targeted medication, meaningful protection against fracture is achievable for most patients across a wide range of risk profiles.
St. Alexius Medical Center has built its osteoporosis program around this proactive philosophy, placing early identification and sustained prevention at the center of clinical practice. The CHI St. Alexius approach treats bone health not as a narrow specialty concern but as an integrated dimension of overall well-being — one that deserves the same systematic attention given to cardiovascular disease, diabetes management, or cancer screening. For anyone who may be at risk or has never been screened despite meeting standard criteria, connecting with a provider affiliated with St. Alexius Medical Center is the right first step — and one that is always worth taking early.
