Regional nerve block anesthesia has transformed the foot and ankle surgery experience over the past two decades. Rather than requiring general anesthesia (with its associated risks, nausea, and prolonged recovery) for many foot procedures, regional blocks allow patients to remain comfortable during surgery and — crucially — to return home pain-free while the block is still active. Understanding how nerve blocks work and what to expect when they wear off helps patients prepare for a smoother recovery.
What Is a Regional Nerve Block?
A regional nerve block involves injecting local anesthetic (typically ropivacaine or bupivacaine, often combined with dexamethasone for extended duration) near specific nerve bundles that supply sensation and motor function to the surgical area. The anesthetic temporarily interrupts nerve conduction — producing numbness, tingling, and weakness in the blocked area for a period lasting hours to days depending on the agent and technique used.
For foot and ankle surgery, two main types of nerve blocks are used:
- Ankle block: Local anesthetic is injected at five points around the ankle, targeting each of the five nerves that supply the foot. Provides complete anesthesia of the foot for routine forefoot, midfoot, and hindfoot procedures. Takes 15–20 minutes to perform; onset of complete numbness within 20–30 minutes.
- Popliteal sciatic nerve block: Ultrasound-guided injection near the sciatic nerve as it divides above the knee. Provides anesthesia from the knee down, including the entire foot and ankle. Preferred for more extensive or painful procedures (Achilles surgery, complex hindfoot reconstruction). Combined with a saphenous nerve block for medial ankle coverage.
Duration: How Long Will the Block Last?
Block duration depends on the anesthetic agent used:
- Lidocaine alone: 2–4 hours (rarely used for surgical blocks due to short duration)
- Bupivacaine (0.5%): 8–12 hours typical for ankle block
- Ropivacaine (0.5%): 8–14 hours
- Ropivacaine or bupivacaine + dexamethasone: 18–36 hours; significantly extended duration
- Liposomal bupivacaine (Exparel): 48–72 hours of extended analgesia
Most patients having standard foot surgery with ropivacaine + dexamethasone can expect 18–30 hours of numbness after the block. Many patients sleep through the first night comfortably without needing pain medication.
Preparing for Your Surgery With a Nerve Block
Key preparation instructions:
- Take oral pain medications before the block wears off: This is the most important instruction. Begin scheduled oral analgesics (ibuprofen, acetaminophen, and/or prescribed medications) 4–6 hours before the expected block resolution, while you are still comfortable. Do not wait until pain develops — catching up to pain is much harder than preventing it.
- Protect the blocked extremity: You cannot feel the blocked foot or leg — protect it from burns, pressure, and injury during the numbness period
- Weight bearing restrictions still apply: A blocked foot is pain-free but not healed — strictly follow your surgical weight-bearing instructions regardless of comfort
- Have pain medications filled before surgery day
When the Block Wears Off
Block resolution typically begins gradually — first with tingling, then progressive return of sensation. The return of sensation may be accompanied by significant discomfort as post-surgical pain fully emerges. Managing this transition with scheduled oral medications is critical for comfort. Contact Dr. Biernacki’s office if pain is uncontrolled despite oral medications.

When to See a Podiatrist
Foot and ankle surgery in 2026 is dramatically different than a decade ago — most procedures are now minimally-invasive, outpatient, and allow weight-bearing within days. Balance Foot & Ankle surgeons have performed 3,000+ foot/ankle surgeries with modern techniques. If another surgeon has recommended a traditional open procedure, a second opinion may reveal a faster, less-invasive option.
