Diabetic Foot Exam: What to Expect 2026 | DPM

Exam Component	Tool / Method	What It Detects	Clinical Significance
Monofilament test (10g)	Semmes-Weinstein 10g monofilament; 10 sites per foot	Loss of protective sensation (LOPS)	LOPS = highest ulceration risk; triggers diabetic shoe referral
Vibration threshold (128Hz tuning fork)	Tuning fork at hallux and medial malleolus	Large fiber sensory neuropathy	Absent vibration sense = advanced neuropathy + fall risk
Ankle-brachial index (ABI)	Handheld Doppler; brachial vs ankle systolic pressure	Peripheral arterial disease (PAD)	ABI below 0.9 = PAD; below 0.6 = critical limb ischemia requiring vascular consult
Skin and nail inspection	Visual + magnification; interdigital spaces	Fissures, maceration, fungal infection, pre-ulcerative lesions	Early intervention prevents ulceration; especially interdigital fungal disease
Structural deformity assessment	Weight-bearing visual inspection; plantar pressure mapping	Hammertoes, Charcot foot, prominent metatarsal heads	High-pressure areas predict future ulcer sites; guides orthotic prescription
Footwear inspection	Inspect shoes for wear pattern, foreign objects, proper fit	Inappropriate footwear; internal wear causing pressure	Improper footwear is a leading cause of diabetic foot ulcers
Wound / callus debridement	Scalpel; performed at same visit	Pre-ulcerative lesions; subkeratotic hemorrhage	Callus debridement removes 30% of plantar pressure; critical ulcer prevention

Risk Category	Criteria	Exam Frequency	Key Interventions
Category 0 (Low risk)	No neuropathy; normal sensation; no deformity; no PAD	Annually	Foot education; proper footwear counseling
Category 1 (Moderate risk)	LOPS or PAD, but no deformity	Every 6 months	Therapeutic footwear; offloading; vascular referral if PAD
Category 2 (High risk)	LOPS + deformity (hammertoe, Charcot, prominent MT heads)	Every 3-4 months	Custom diabetic shoes + orthotics (Medicare-covered); regular debridement
Category 3 (Very high risk)	Prior ulcer or amputation history	Every 1-3 months	Intensive monitoring; wound surveillance; multidisciplinary team

Diabetes is the leading cause of non-traumatic lower limb amputations in the United States. The vast majority of these amputations are preventable with proper foot care and regular podiatric monitoring. The annual diabetic foot exam is a cornerstone of diabetes management — detecting early warning signs before they become catastrophic complications.

Why Diabetics Are at High Risk

Peripheral neuropathy destroys protective sensation — patients cannot feel injuries, pressure sores, or infections. Peripheral artery disease (PAD) reduces blood flow, impairing wound healing. Together, they create conditions for ulceration, infection, and amputation.

Components of a Comprehensive Diabetic Foot Exam

Neurological assessment: 10-g monofilament testing at 10 sites on the sole. Vibration sense testing. Ankle reflex evaluation. Vascular assessment: Palpation of pedal pulses. Ankle-brachial index if pulses are diminished. Dermatological examination: Skin integrity, callus locations, interdigital maceration, nail thickness and fungus. Musculoskeletal assessment: Foot deformities, range of motion, calf muscle tightness. Footwear evaluation: Adequacy of current shoes and socks.

Risk Stratification

Low risk (normal sensation and pulses, no deformity) — annual exam. Moderate risk (neuropathy or PAD but no deformity) — every 3-6 months. High risk (neuropathy + deformity or PAD) — every 1-3 months. Very high risk (prior ulcer or amputation) — every 1-3 months with enhanced surveillance.
