Foot and ankle pain affects 24–35% of older adults and is a leading cause of functional limitation, reduced walking speed, and falls in the elderly population. The aging foot undergoes predictable structural changes — fat pad atrophy, ligamentous laxity, reduced sensory perception, skin fragility, and cumulative joint degeneration — that create a specific pattern of conditions disproportionately prevalent in patients over 65. Understanding these age-related changes guides both preventive foot care and targeted treatment of the most common geriatric podiatric conditions.

Age-Related Structural Changes in the Foot

The plantar fat pad — the natural shock-absorbing cushion beneath the heel and metatarsal heads — loses 30–50% of its thickness and elasticity by age 70 through fibroseptal rupture, decreased fat cell size, and reduced proteoglycan content. This atrophy directly increases plantar pressure under bony prominences and is a major driver of metatarsalgia, heel fat pad syndrome, and ulceration risk in neuropathic patients. Ligamentous laxity increases with age, contributing to flatfoot progression, MTP joint instability, and hallux valgus advancement. Peripheral sensory loss — even without formal diabetes or neuropathy — occurs in 30% of adults over 65 from normal aging of the peripheral nervous system, increasing fall risk and delaying injury recognition.

Most Common Geriatric Foot Conditions

Hallux valgus (bunion) progresses with age and is more symptomatic in older women due to cumulative shoe pressure and ligamentous laxity. Acquired flatfoot from posterior tibial tendon insufficiency is most prevalent in women in their 50s–70s. Hammer toe deformity from intrinsic muscle atrophy accumulates with age. Ankle and first MTP joint osteoarthritis produces progressive stiffness and pain with ambulation. Peripheral artery disease prevalence increases dramatically after age 65, requiring regular ABI screening. Onychomycosis affects 30% of adults over 70. Skin fragility with impaired wound healing makes seemingly minor injuries (blisters, fissures, nail injuries) medically significant in elderly patients with diabetes or PAD.

Falls and Foot Pathology

Foot conditions are independently associated with falls in older adults — reduced ankle dorsiflexion, plantar foot pain, hallux valgus, and peripheral sensory loss each increase falls risk by 30–60% in prospective studies. Custom orthotics with metatarsal pad and deep heel cup improve balance and reduce falls risk in older adults with foot pain. Extra-depth shoes with slip-resistant soles, firm heel counters, and adequate toe box depth improve stability. Assessment for ankle equinus (reduced dorsiflexion) — common from years of heel shoe wear and calf shortening — is a modifiable falls risk factor treatable with gastrocnemius stretching, serial casting, or surgical gastrocnemius recession.

Medicare-Covered Preventive Foot Care

Medicare Part B covers specific preventive foot care services for high-risk patients: diabetic foot care visits (nail trimming, callus debridement, examination) every 6 months for patients with peripheral neuropathy or PAD; therapeutic shoes and insoles annually for patients with diabetes and additional qualifying foot conditions; and custom orthotics when medically documented biomechanical pathology is present. Understanding these coverage provisions ensures elderly patients access the preventive care that reduces ulceration and amputation risk.
