Preventing Falls and Fractures in Older Adults

Falls represent the leading cause of injury-related death among adults aged 65 and older in the United States, according to the Centers for Disease Control and Prevention (CDC). Each year, approximately 3 million older adults are treated in emergency departments for fall injuries, and more than 800,000 are hospitalized — most often for hip fractures or head trauma. This page covers the clinical and structural framework for fall and fracture prevention, including how risk factors interact, the environments and circumstances where falls are most likely, and how clinical and community-level interventions are classified.

Definition and Scope

Fall prevention in older adults is a defined public health and orthopedic care domain concerned with reducing the incidence of unintentional falls and the fractures that frequently follow. The CDC's STEADI (Stopping Elderly Accidents, Deaths & Injuries) initiative provides a structured clinical framework used by healthcare providers to screen, assess, and intervene based on measurable fall risk.

The scope extends beyond accidental slips. It encompasses bone fragility, neuromuscular decline, medication side effects, and environmental hazards — all of which interact to raise fracture risk. Osteoporosis and bone health are central to this scope because low bone mineral density significantly increases the likelihood that a fall will result in a fracture rather than a bruise. The National Osteoporosis Foundation (NOF) estimates that osteoporosis is responsible for approximately 2 million fractures annually in the United States.

For regulatory and clinical program purposes, fall prevention intersects with orthopedic care standards, geriatric medicine protocols, and the regulatory context for orthopedics that governs facility-level safety metrics and quality reporting requirements under CMS (Centers for Medicare & Medicaid Services).

How It Works

Fall and fracture prevention operates through a layered, multi-domain risk reduction model. The STEADI framework organizes this into three phases:

1. Screen — Identify patients at elevated risk using validated tools such as the Timed Up and Go (TUG) test, a 30-Second Chair Stand test, and a 4-Stage Balance Test.
2. Assess — Evaluate modifiable risk factors including gait abnormalities, orthostatic hypotension, vision impairment, polypharmacy (defined as concurrent use of 5 or more medications), and home hazards.
3. Intervene — Apply targeted strategies drawn from evidence-based programs, which may include exercise, medication review, vitamin D supplementation, or referral for bone density testing.

Bone density testing via dual-energy X-ray absorptiometry (DEXA) is the standard method for quantifying fracture risk. A T-score of −2.5 or below at the hip or lumbar spine meets the diagnostic threshold for osteoporosis under World Health Organization (WHO) criteria, placing individuals in a high-fracture-risk category.

Exercise interventions follow two distinct classifications:

• Balance and gait training — Programs such as the Otago Exercise Programme, developed by the University of Otago and validated in randomized controlled trials, target lower-limb strength and postural stability.
• Resistance and weight-bearing exercise — Designed to maintain or improve bone mineral density, these protocols reduce the skeletal vulnerability that converts a fall into a fracture.

Vitamin D deficiency measurably increases fall risk by impairing neuromuscular function. The U.S. Preventive Services Task Force (USPSTF) has evaluated supplementation specifically in fall prevention contexts, with guidance focused on community-dwelling adults aged 65 and older.

Common Scenarios

Fall-related fractures do not occur uniformly across settings or activities. The most clinically significant scenarios fall into three categories:

Indoor falls in the home environment account for the majority of fall events in older adults. Bathroom surfaces, stairs, and low-contrast lighting are the most frequently documented hazard clusters. Hip fractures resulting from lateral falls onto hard flooring carry a 20–30% one-year mortality rate in adults over 65, according to data published by the American Academy of Orthopaedic Surgeons (AAOS).

Post-surgical and post-hospitalization falls represent a distinct high-risk window. Individuals recovering from total knee replacement, total hip replacement, or fracture fixation face compounded risk from deconditioning, altered proprioception, and temporary medication regimens that may include sedating agents.

Community and outdoor falls are more common in adults with higher baseline mobility. Uneven terrain, curb transitions, and icy surfaces are primary hazard sources. This population is also more likely to sustain wrist and forearm fractures from outstretched-hand impact (Colles' fractures), rather than hip fractures.

Across all scenarios, polypharmacy is a consistent amplifier. Medications in four drug classes — benzodiazepines, antihypertensives, antidepressants (particularly SSRIs), and anticholinergics — are specifically identified in the American Geriatrics Society Beers Criteria as increasing fall risk in older adults.

Decision Boundaries

Not all fall risk profiles require the same intervention intensity. Clinical decision-making in fall prevention draws clear categorical boundaries:

Low risk — Adults with no reported falls in the prior 12 months, normal TUG scores (under 12 seconds), and no gait abnormalities are typically managed with general counseling and home safety education.

Moderate risk — One fall in the prior year without injury, or balance assessment scores in the borderline range, warrants structured exercise referral and medication reconciliation.

High risk — Two or more falls in the prior year, a single injurious fall, or confirmed osteoporosis on DEXA scan elevates the patient to intensive intervention, including physical therapy and rehabilitation, pharmacological bone protection (bisphosphonates or other agents per prescribing guidelines), and possible referral to a specialist through pathways described across the orthopedicsauthority.com resource index.

The distinction between fall prevention and fracture prevention reflects two parallel intervention targets. Preventing the fall requires neuromuscular and environmental strategies. Preventing a fracture given a fall requires skeletal resilience — primarily addressed through bone density management, adequate calcium and vitamin D intake, and reduction of corticosteroid use where clinically possible.

Hip protectors — padded garments worn over the greater trochanter — represent a passive structural intervention. Evidence from the Cochrane Collaboration indicates they reduce hip fracture incidence in nursing home residents, though adherence rates in community settings are consistently low.
