| Block Type | Nerves Blocked | Area Anesthetized | Technique | Common Use |
|---|---|---|---|---|
| Digital Block (Web Space) | Proper digital nerves (medial and lateral of target toe) | Entire toe distal to MTPJ | 1–2 mL lidocaine each side of web space base; bilateral approach | Ingrown toenail, nail avulsion, toe surgery, exostosis |
| Digital Block (Dorsal-Plantar) | Dorsal and plantar proper digital nerves | Entire toe | 1 mL dorsal + 1 mL plantar injection at base of proximal phalanx bilaterally | Big toe procedures (hallux); subungual exostosis |
| Posterior Tibial Nerve Block | Posterior tibial nerve → medial/lateral plantar nerves | Entire plantar foot; heel | 2–5 mL at medial ankle posterior to tibial artery; posterior to medial malleolus | Plantar fascia release; plantar foot surgery; heel procedures |
| Sural Nerve Block | Sural nerve | Lateral ankle; 5th toe; lateral midfoot | 2–3 mL lateral ankle between Achilles and fibula | Lateral ankle procedures; 5th metatarsal surgery; combined with PT block |
| Ankle Block (Complete) | 5 nerves: posterior tibial, sural, saphenous, superficial peroneal, deep peroneal | Entire foot | Sequential injection at 5 anatomic landmarks around ankle | Forefoot/midfoot surgery; combined with sedation; avoids spinal |
| Agent | Onset | Duration | Concentration Used | Notes |
|---|---|---|---|---|
| Lidocaine 1% (plain) | 2–5 minutes | 1–2 hours | 1% without epinephrine for digits | Fastest onset; preferred for in-office nail procedures; NO epinephrine in digits |
| Lidocaine 2% | 2–5 minutes | 1–2 hours | 2% for denser block | Faster onset with higher concentration; same duration |
| Bupivacaine 0.25–0.5% | 10–20 minutes | 4–8 hours | 0.25% for nerve block; 0.5% for longer procedures | Long-acting; excellent for post-op pain control; slower onset |
| Lidocaine + Bupivacaine (combo) | 2–5 minutes (lido onset) | 4–8 hours (bupivacaine duration) | 1:1 mix 1% lido + 0.25% bupivacaine | Best of both — fast onset with long duration; most common surgical combination |
| Mepivacaine 1–2% | 3–5 minutes | 2–3 hours | 1–2% | Intermediate duration; less vasodilation than lidocaine; good for moderate procedures |

Quick Answer:
Quick Answer: Digital nerve blocks are local anesthetic injections that temporarily numb an entire toe — allowing painless in-office procedures including permanent ingrown toenail correction, nail removal, wart debridement, and digital lesion excision without sedation or hospital visits. Buffered lidocaine (mixed with sodium bicarbonate) significantly reduces injection discomfort. The block takes effect within 5 minutes and provides 1-3 hours of complete anesthesia. Most patients are surprised by how comfortable in-office podiatric procedures are with appropriate local anesthesia.
Many patients delay necessary foot procedures out of fear — fear of pain, fear of hospitals, and fear of anesthesia. At Balance Foot & Ankle PLLC, the vast majority of common foot procedures are performed in the office under local anesthesia — no hospital, no sedation, no IV, no overnight stay. Digital nerve blocks provide complete, reliable anesthesia for any toe procedure, making in-office podiatric procedures significantly more comfortable than most patients anticipate.
What is a Digital Nerve Block?
A digital nerve block is an injection of local anesthetic (buffered lidocaine) at the base of the toe — anesthetizing the digital nerves that provide sensation to the entire toe. Two small injections at the medial and lateral base of the digit provide complete anesthesia within 5 minutes. Buffered lidocaine (lidocaine mixed with sodium bicarbonate to neutralize acidity) significantly reduces the brief stinging sensation of injection compared to plain lidocaine. Most patients rate the injections as a 2-3/10 on the pain scale. Once blocked, the toe is completely numb — no pain during the procedure itself.
In-Office Procedures Performed Under Digital Block
Permanent Ingrown Toenail Correction (Partial Matrixectomy): The most common in-office procedure — removal of the offending nail border and chemical ablation of the matrix under digital block. 15-minute procedure, 95%+ success rate. Complete Nail Avulsion: For fungal or destroyed nail plates — removal of the entire nail plate under block for nail bed treatment. Subungual Exostosis Excision: Removal of bone spurs under the nail under digital block with fluoroscopy guidance. Plantar Wart Debridement and Treatment: Aggressive surgical debridement of plantar warts under metatarsal block. Digital Cyst or Lesion Excision: Mucous cysts, fibromata, and other digital lesions excised under block.
Ankle Block for Forefoot Procedures
For more extensive forefoot procedures, a Mayo or sinus tarsi ankle block anesthetizes all five toes simultaneously — allowing forefoot surgery without sedation. Particularly useful for patients undergoing multiple hammertoe corrections or bunion procedures under local-only anesthesia. Dr. Biernacki performs select forefoot surgical procedures under ankle block with monitored local anesthesia only — no general anesthesia required for many outpatient forefoot cases.

✅ Pros / Benefits
- Digital nerve blocks provide complete toe anesthesia for painless in-office procedures
- Buffered lidocaine significantly reduces injection discomfort
- In-office procedures eliminate hospital costs, sedation risks, and scheduling delays
- Most patients are considerably more comfortable than anticipated
❌ Cons / Risks
- Digital block wears off in 1-3 hours — post-procedure soreness managed with OTC pain medication
- Epinephrine-containing anesthetics avoided in digital blocks due to digital artery vasospasm risk
- Complex procedures (ankle reconstruction, Achilles repair) still require surgical center with full anesthesia
Dr. Tom Biernacki’s Recommendation
I spend a meaningful amount of time with first-time patients explaining what the digital block will feel like — because their anticipatory anxiety often exceeds the actual experience considerably. I use buffered lidocaine exclusively, inject slowly, and after the first minute, the toe is numb. The most common reaction after an ingrown toenail procedure is ‘that was it?’ I would rather take two extra minutes to block the toe properly than rush an anesthetic and have a patient experience discomfort during the procedure.

Frequently Asked Questions
Does a digital nerve block hurt?
The digital nerve block involves two small injections at the base of the toe — typically rated 2-3 out of 10 in discomfort by most patients. Dr. Biernacki uses buffered lidocaine (mixed with sodium bicarbonate to reduce acidity) which significantly reduces the stinging sensation compared to plain lidocaine. The injection discomfort lasts approximately 10-15 seconds per site. Once the block is in effect (5 minutes), the toe is completely numb and the procedure is painless.
What procedures can be done in the office without going to the hospital?
Common in-office podiatric procedures: permanent ingrown toenail correction (matrixectomy), complete toenail removal, cortisone injections, plantar wart treatment, skin lesion excision, mucous cyst excision, small exostosis removal, nail biopsy, and wound debridement. Selected forefoot surgeries (hammertoe correction, exostectomy) can be performed at an outpatient surgical center under ankle block without general anesthesia. Major reconstructive surgery (ankle arthrodesis, total ankle replacement, Lapidus fusion, Achilles repair) requires a surgical center.
How long does a digital nerve block last?
A digital nerve block with plain lidocaine lasts 1–3 hours — sufficient for all in-office procedures. Bupivacaine (longer-acting local anesthetic) can be mixed with lidocaine to extend the duration to 4–6 hours for procedures requiring prolonged anesthesia or for postoperative comfort. After the block wears off, the toe may be sore from the procedure — most patients manage this with over-the-counter ibuprofen or acetaminophen. Prescription pain medication is available if needed.
Can I drive after a digital nerve block?
Yes — digital nerve blocks anesthetize only the toe, not the foot or ankle. Normal foot sensation and motor function are maintained. Driving after an in-office digital block procedure is safe. If the procedure involves the right great toe with extensive dressing, comfort behind the pedal should be confirmed before driving. Patients who receive sedation for procedures at surgical centers cannot drive and need a designated driver.
