Morton’s neuroma is a painful nerve condition that develops in the ball of the foot, typically between the third and fourth toes. For patients who have tried conservative treatment without lasting relief, cryosurgery—also called cryoablation or cryoneurolysis—offers a minimally invasive alternative to open neuroma surgery. Michigan Avenue Podiatry performs cryosurgery for Morton’s neuroma at our Chicago office at 30 North Michigan Avenue, Suite 1220, serving patients from the greater Chicagoland area.

What Is Cryosurgery / Cryoablation for Morton’s Neuroma?

Cryosurgery for Morton’s neuroma is an image-guided procedure in which a slender probe is inserted through a small puncture in the skin under ultrasound guidance. The probe tip is cooled to approximately −50°C (−58°F), creating a small “ice ball” that envelops the irritated nerve. At that temperature, the cell membranes within the nerve sheath rupture, disrupting the fibers that transmit pain—without removing the nerve itself.

The approach is known as cryoneurolysis when applied to peripheral nerves. Because the nerve is disrupted rather than excised, the risk of stump neuroma formation (a complication seen after surgical neurectomy) is substantially reduced. The surrounding ligamentous and soft tissue structures are preserved, which allows for rapid functional recovery.

A 2024 study published in CardioVascular and Interventional Radiology found a 98.1% technical success rate for ultrasound-guided cryoneurolysis in Morton’s neuroma patients. (Source: pubmed.ncbi.nlm.nih.gov/38438685/)

Cryosurgery vs. Traditional Neuroma Surgery

Traditional neuroma surgery—neurectomy—involves making a small incision on the top or bottom of the foot, isolating the affected nerve, and surgically removing the enlarged segment. The procedure requires stitches, a period of restricted weight-bearing, and a recovery of four to six weeks before return to normal footwear and activity. Published data cite success rates of 50–85% for surgical neurectomy and adverse event rates of 14–21%, including the risk of stump neuroma formation at the cut nerve end.

Cryosurgery for Morton’s neuroma is performed entirely through a skin puncture—no incision, no stitches, and no surgical wound. The 15-minute in-office procedure allows patients to walk out the same day and return to normal shoes within approximately three days. Cryosurgery is performed as a cash-pay procedure at Michigan Avenue Podiatry. Our team will review costs during your consultation.

What to Expect During the Cryosurgery Procedure

The procedure follows a straightforward, well-established protocol at our Chicago office:

1. Local anesthetic injection: A small amount of local anesthetic is injected around the treatment area to numb the foot before the probe is placed.
2. Ultrasound-guided probe placement: Using real-time ultrasound imaging, the physician guides the cryoprobe precisely to the neuroma site through a skin puncture approximately 3–5 mm in diameter.
3. 15-minute freeze cycle: The probe tip cools to −50°C, creating an ice ball around the neuroma. The freeze cycle typically takes 10–15 minutes.
4. Dressing applied: A small adhesive dressing covers the puncture site. No sutures are required.
5. Walk out same day: Patients leave the office on their own feet and may drive home. Most wear comfortable footwear immediately after the procedure.

Recovery After Cryosurgery for Morton’s Neuroma

Cryosurgery recovery is significantly shorter than recovery from open neuroma surgery. Most patients can expect the following timeline:

• Day of procedure: Walk out of the office. Mild soreness and swelling around the puncture site is normal. Avoid pools, hot tubs, and submerging the foot for 48 hours.
• Days 1–3: Return to normal shoes. Soft, comfortable footwear recommended. No stitches to protect or remove.
• Weeks 1–2: Return to full daily activity and light exercise. Avoid high-impact sports until weeks 3–4.
• 6-week follow-up: A follow-up appointment assesses the neuroma’s response to treatment. Most patients notice continued pain improvement over 4–8 weeks as the disrupted nerve tissue resolves.

Is Cryosurgery Right for You?

Cryosurgery is best suited for patients who meet the following criteria:

• Failed conservative treatment—including custom orthotics, cortisone injections, and metatarsal padding—for three or more months
• Morton’s neuroma confirmed on diagnostic ultrasound or MRI
• No prior neuroma surgery at the same site
• Preference for a minimally invasive approach with rapid return to activity

Patients who have already undergone open neurectomy at the same location may require individualized evaluation to determine whether cryosurgery is appropriate. Our physicians will review your imaging and treatment history at your consultation to provide a personalized recommendation.
