Toenail avulsion is the removal of part or all of a toenail from its nail bed, either by a clinician in a controlled procedure or as the result of an injury that tears the nail away. It is one of the most common minor surgeries performed in primary care and podiatry, typically used to treat severe ingrown toenails, nail infections, or trauma. The procedure itself is straightforward and done under local anesthesia, but the recovery period and what happens to the nail matrix afterward matter more to long-term outcomes than the removal itself.
Why Toenail Avulsion Is Performed
The most frequent reason for planned toenail avulsion is a stubbornly ingrown toenail, known clinically as onychocryptosis. When the edge of a nail digs into the surrounding skin fold, the area becomes painful, swollen, and prone to infection. Conservative measures like proper trimming, cotton wedges, or gutter splints can help in early stages, but surgical removal is reserved for severe or repeatedly recurring cases where gentler approaches have failed.
Trauma is the other major cause. A heavy object dropped on a toe, a stubbing injury, or a sports collision can crack, fragment, or partially rip a toenail from its bed. When the nail plate is damaged or a fracture underneath involves the growth center of the nail, exploration and repair of the nail bed are typically needed, which means removing the damaged nail first.
Less commonly, avulsion is used to treat fungal nail infections that have not responded to oral or topical medications, or to access the nail bed for biopsy when a suspicious lesion sits beneath the nail plate. In each scenario the goal is the same: get the nail out of the way so the underlying tissue can be treated, repaired, or allowed to heal.
Partial Versus Total Avulsion
Not every avulsion means losing the entire toenail. In fact, partial avulsion is far more common. When only one side of the nail is ingrown, a clinician removes just the offending lateral strip of nail, leaving the rest of the nail plate intact. This approach preserves the nail’s appearance and function while eliminating the source of pain.
Total avulsion removes the entire nail plate. It tends to be reserved for cases where the whole nail is damaged by trauma, where a fungal infection has destroyed the nail beyond saving, or where the problem affects both sides of the nail. Because the nail matrix (the tissue at the base that produces new nail) is left intact in a simple avulsion, the toenail will regrow in either case. That regrowth takes roughly six to twelve months for a big toenail, and the new nail does not always come back perfectly shaped.
The distinction between partial and total avulsion matters most when you factor in recurrence. Removing just the problematic strip of an ingrown nail provides relief, but if the nail edge grows back into the same curved pattern, the problem returns. That is why avulsion is frequently combined with a procedure called matrixectomy, which destroys a portion of the nail’s growth center so the offending strip never regrows.
How the Procedure Is Done
Toenail avulsion is an office procedure, not an operating-room surgery. You sit or lie back, the toe is cleaned, and a local anesthetic is injected to numb the area completely. The most traditional approach is a digital nerve block at the base of the toe, sometimes called an H-block, which numbs the entire toe by targeting the nerves running along each side. A newer alternative, the V-block, places injections in a V-shaped pattern closer to the nail itself. A randomized trial found that the V-block achieved effective anesthesia in most patients within ten to twenty minutes and was a safe alternative to the traditional block, though some patients needed a small supplemental injection.
A comparative study found that the V-block offers rapid onset and effective pain relief suited to routine procedures, while the traditional H-block provides more sustained and comprehensive numbness, making it preferable for more complex operations.
Once the toe is numb, the clinician uses a flat instrument to separate the nail plate from the nail bed, working from the free edge back toward the cuticle. For a partial avulsion, the nail is split lengthwise with scissors or a nail splitter, and only the freed strip is pulled away. For a total avulsion, the entire plate is lifted and removed. The whole process usually takes just a few minutes. There is little to no pain during the procedure because of the anesthesia, though you will feel pressure and tugging.
Matrixectomy and Preventing Regrowth
If the goal is simply to access the nail bed for treatment or biopsy, the nail is removed and nothing else is done to the matrix. But for chronic ingrown toenails, avulsion alone has a high recurrence rate. One study found recurrence as high as 20% when partial nail avulsion was performed without any additional treatment to the matrix.
Matrixectomy destroys the cells responsible for producing the nail, either chemically or surgically. When done after a partial avulsion, it permanently narrows the nail by preventing the problematic edge from regrowing. After a total avulsion, it stops the nail from coming back entirely.
Chemical Matrixectomy
The most widely used method involves applying a chemical agent to the exposed nail matrix after the nail or nail strip has been removed. Phenol has been the traditional choice for decades. A study comparing three chemical agents found meaningful differences in recovery: trichloroacetic acid (TCA) at 90% concentration was associated with the least postoperative pain (about one day on average), the shortest period of wound drainage (roughly six days), and the fastest healing (around 27 days for the skin to fully close over). Sodium hydroxide fell in the middle, while phenol caused the most pain (about nine days), the longest drainage (two weeks), and the slowest healing (around 40 days).
That slower healing with phenol matters practically. A separate trial comparing chemical matrixectomy with phenol against a surgical reconstruction technique found that the phenol group took an average of 21 days to heal, compared to about eight days for the reconstruction group. Both had very low recurrence rates, under 3%, but the phenol group had a higher infection rate of roughly 6% versus 1.5%.
Despite those drawbacks, chemical matrixectomy with phenol remains popular because it is simple, requires no sutures, and has a long track record. The newer data on TCA suggest it may offer a gentler recovery with comparable effectiveness, though it has not yet displaced phenol in most clinical settings.
Surgical Matrixectomy
Rather than using chemicals, some surgeons physically cut out the nail matrix tissue. The Winograd technique is one of the most established methods: after removing the offending nail strip, the surgeon excises a wedge of matrix tissue and the overlying nail fold, then closes the wound with sutures. A retrospective study of 68 patients who underwent the Winograd technique found a recurrence rate of about 13%, and noted that narrowing of the remaining nail plate was a cosmetic disadvantage.
A more recent study comparing the modified Winograd method to partial resection with electrocoagulation concluded that the modified Winograd technique remains effective, with high patient satisfaction and low recurrence rates. Numerous other surgical approaches exist, including radiofrequency ablation, laser ablation, and various flap procedures, with the choice depending on how severe the problem is and whether it keeps coming back.
What Recovery Looks Like
Recovery after toenail avulsion is not complicated, but it is slower than most people expect. The nail bed is essentially an open wound once the nail plate is gone, and it needs to be kept clean and protected while new tissue forms.
Right after the procedure, the toe is bandaged. You can usually walk out of the office, though the toe will be sore once the anesthesia wears off. Most clinicians recommend keeping the foot elevated for the first day or two, taking over-the-counter pain relievers, and soaking the toe in warm salt water once or twice daily after the first 24 to 48 hours. You will need to change the dressing regularly, often daily, for the first week or two.
Healing times depend heavily on whether the avulsion was partial or total. A study looking at wound care after toenail surgery found that partial avulsion wounds healed in roughly 20 days on average, while total avulsion wounds took closer to 45 to 52 days. That is a significant difference, and it underscores why partial avulsion is preferred when the clinical situation allows it.
If a chemical matrixectomy was performed alongside the avulsion, expect some wound drainage during the first couple of weeks. The chemical burn to the matrix tissue produces a weeping wound that gradually dries and re-epithelializes. With phenol, this drainage phase can last about two weeks. With TCA, it is considerably shorter.
Pain at the First Dressing Change
One aspect of recovery that does not get discussed enough is the discomfort of the first postoperative dressing change. A study examining the experience of patients, nurses, and observers found that removing the initial gauze dressing from the raw nail bed caused significant pain. This led to calls for reconsidering what type of dressing is applied immediately after surgery, since the gauze can adhere to the wound bed and pulling it away essentially reopens the wound surface.
Some clinicians use non-adherent dressings or petroleum-based gauze to reduce this problem. The evidence on dressing type is mixed. One trial comparing honey-based dressings to paraffin-impregnated gauze after toenail avulsion found that for partial avulsions, the paraffin gauze group actually healed faster (about 20 days versus 32 days with the honey dressing). For total avulsions, neither dressing showed a clear advantage. The practical takeaway is to ask your clinician what dressing they plan to use and whether they have a strategy for minimizing pain at that first change. Soaking the dressing before removal can help loosen it and reduce tearing at the wound surface.
Complications Worth Knowing About
Toenail avulsion is a minor procedure, but it is not complication-free. The most common issues are:
- Recurrence: For ingrown toenails, the nail edge can grow back into the skin fold if the matrix was not adequately destroyed. Recurrence rates vary widely depending on whether matrixectomy was performed and which technique was used. Without matrixectomy, recurrence can reach 20%. With phenol matrixectomy, recurrence drops to low single digits in most studies.
- Infection: The open wound is vulnerable to bacterial infection, especially in the first week. Signs include increasing redness, swelling, warmth, and pus. Infection rates in studies of chemical matrixectomy hover around 2% to 6%, depending on the agent used.
- Nail dystrophy: When the nail does regrow after a simple avulsion (without matrixectomy), it may come back thickened, ridged, or discolored. Damage to the matrix during the procedure can cause permanent changes to the nail’s appearance.
- Bleeding: The nail bed is well-supplied with blood, and some oozing is normal in the first day or two. Significant bleeding is uncommon but can occur, particularly in patients on blood-thinning medications.
People with diabetes, peripheral vascular disease, or compromised immune systems face higher risks of poor healing and infection. If you fall into one of those categories, your clinician will likely take extra precautions and monitor recovery more closely.
When You Might Not Need Surgery
Avulsion is not always the first step for an ingrown toenail. Several conservative and semi-invasive approaches exist that can resolve milder cases without removing any nail at all. A gutter splint, a small tube placed along the ingrown nail edge to lift it away from the skin fold, can provide immediate pain relief. A cotton nail cast made with cotton fibers and cyanoacrylate adhesive (essentially medical-grade superglue) can redirect the nail’s growth. Taping the lateral skin fold away from the nail edge is another simple technique. Orthonyxia, the use of wire or composite braces glued to the nail surface to gradually correct its curvature, is increasingly popular in Europe and Asia.
These approaches work best for mild to moderate cases. If the ingrown nail is infected, deeply embedded, or has recurred multiple times despite conservative management, avulsion with matrixectomy is the more definitive solution. The evidence consistently shows that conservative treatments handle early-stage symptoms well, while surgical options are needed for severe or recurring problems.
Quality of Life After the Procedure
Chronic toenail problems are easy to dismiss as trivial, but they meaningfully affect daily life. Pain with every step, difficulty wearing closed shoes, and recurring infections take a toll that builds over months or years. This is especially true in older adults, for whom foot pain limits mobility and independence.
A study examining quality of life in older patients after toenail surgery found measurable improvement in foot-related quality of life scores following the procedure. The gains were not just about pain relief. Patients reported better function and less self-consciousness about the appearance of their feet. For people who had been limping or avoiding walking, getting the problem definitively fixed changed how they moved through their day.
This quality-of-life dimension is worth considering if you have been putting off treatment because the problem seems minor. A chronically ingrown or damaged toenail is not dangerous in most cases, but the cumulative effect of ongoing discomfort, repeated infections, and limited footwear choices adds up. The procedure itself is quick, the recovery is manageable, and for the majority of patients, the problem does not come back once the matrix has been appropriately treated.
Trauma-Related Avulsion Versus Planned Avulsion
The experience is quite different depending on whether your toenail was removed on purpose or ripped off by accident. In a traumatic avulsion, the nail bed underneath may be lacerated, crushed, or associated with a fracture of the underlying bone. Treatment priorities shift from simply managing the nail to assessing and repairing the deeper structures. Nail bed lacerations often require sutures under magnification to ensure the nail grows back as normally as possible. If the bone beneath is fractured and the break extends into the nail’s growth zone, that fracture needs to be stabilized, sometimes with the nail plate itself acting as a natural splint after it is cleaned and replaced into position.
Traumatic nail injuries are common in children, who tend to catch fingers and toes in doors and heavy objects. In these cases, the concern is not just about the current wound but about long-term nail growth. The germinal matrix in a child is still developing, and damage to it can cause lifelong nail deformity. That is why the threshold for surgical exploration and repair tends to be lower in traumatic cases, particularly when the nail plate is visibly disrupted or when imaging shows a fracture involving the growth area.
If you lose a toenail in an accident, the general advice is to save the nail if possible (wrap it in moist gauze), control bleeding with gentle pressure, and seek medical attention the same day. Even if the nail bed looks intact, a clinician can assess whether there is hidden damage that warrants repair. Left unrepaired, a significantly injured nail bed can produce a nail that splits, ridges, or fails to adhere to the bed properly, problems that are much harder to fix after the tissue has healed in a disorganized pattern.
