Digital Block Anesthesia: Great Toe and Lesser Toe Block Technique for Podiatric Procedures

Medically reviewed by Dr. Tom Biernacki, DPM — Board-Certified Podiatric Surgeon — Balance Foot & Ankle, Howell & Bloomfield Township, MI. Last updated April 2026.

Digital block anesthesia — local anesthetic injection blocking the digital nerves at the base of a toe — provides complete anesthesia for all in-office podiatric procedures of the toe: ingrown toenail removal, nail avulsion, subungual exostosis excision, flexor tenotomy, and incision and drainage of paronychia. Mastery of digital block technique produces reliable, rapid, and comfortable anesthesia with minimal complications.

Anatomy

Each toe is supplied by four digital nerves: two dorsal digital nerves (branches of the superficial peroneal nerve for the lesser toes, deep peroneal nerve for the first web space) and two plantar digital nerves (branches of the medial and lateral plantar nerves). The digital nerves run along the medial and lateral borders of the proximal phalanx in the plantar-lateral position. A complete digital block requires deposition of local anesthetic around all four nerves at the base of the toe.

Technique: Great Toe Block

Two-injection technique for the great toe: First injection — dorsomedial approach: insert a 27-gauge needle at the dorsomedial base of the proximal phalanx and advance slightly plantarward while injecting 1.5mL to block the medial plantar and medial dorsal digital nerves; redirect the needle dorsally and inject 0.5mL subcutaneously to block the dorsomedial branch. Second injection — dorsolateral approach: same technique on the lateral side (1.5mL plantar + 0.5mL dorsal). Total volume: 4–5mL per great toe. Wait 3–5 minutes for onset before proceeding. Lesser toe block: single injection at the base of the proximal phalanx with a field block — insert a 27-gauge needle dorsomedially and inject 1mL while advancing plantarward; repeat dorsally and on the lateral side with 1mL each — total 2–3mL per lesser toe. Local anesthetic selection: 1% or 2% lidocaine (onset 2–3 minutes, duration 1–2 hours) or 0.5% bupivacaine (onset 5–10 minutes, duration 4–8 hours) — do NOT use epinephrine-containing anesthetic for digital blocks (risk of digital ischemia). Dr. Biernacki at Balance Foot & Ankle performs in-office nail and toe procedures under digital block anesthesia for same-day pain relief.

Frequently Asked Questions

When should I see a podiatrist?

See a podiatrist for any foot or ankle pain that persists more than 2 weeks, doesn’t improve with rest, limits your daily activities, or is accompanied by swelling, numbness, or skin changes. People with diabetes or circulation problems should see a podiatrist regularly even without symptoms.

What does a podiatrist treat?

Podiatrists diagnose and treat all conditions of the foot, ankle, and lower leg including plantar fasciitis, bunions, hammertoes, toenail problems, heel pain, nerve pain, diabetic foot care, sports injuries, fractures, and foot deformities — both surgically and non-surgically.

What can I expect at my first podiatry visit?

Your first visit includes a full medical history, physical examination of your feet and gait, and in-office diagnostic imaging if needed (X-rays, ultrasound). We’ll discuss your diagnosis and create a plan tailored to your foot type. Most visits take 30–45 minutes.

Most Common Mistake We See

The most common mistake we see is: Waiting too long before seeking care. Fix: any foot pain lasting more than 4 weeks, or any sudden severe symptom, deserves a professional evaluation rather than more rest.
