Image de :Torn Toenail: What to Do After Trauma?

A torn toenail can be painful and distressing after a blow or crushing injury to the foot. Fortunately, certain actions can help limit complications and promote good healing. This relatively common injury can occur in many situations and is sometimes not serious, but since the toenail’s main function is to protect the toe, if it tears off, it is possible that the toe itself has also suffered an injury or fracture. Fortunately, there are solutions to care for a torn nail and ensure proper regrowth. To avoid infections and further complications, here are the steps to take to provide first aid to a toenail that is partially or completely torn off.

How Does Losing a Toenail Happen?

Following a blow, for example if you stub your toe or it is crushed by a heavy object, the toenail can be totally or partially torn off. Playing sports, working in construction, or simply walking barefoot can expose you to this risk. 

In some cases, the most painful ones, the nail tears off immediately. The severity of the impact may indicate a significant trauma to the toe bone; it is therefore advisable to consult promptly for X-rays.  

In other situations, the nail may discolor (turn blue), then fall off a few days later. In fact, the loss of the nail in this case is related to the formation of a hematoma (the bruise). The blood that accumulates pushes the nail, which gradually lifts off its bed. To relieve your nail, you can consult a healthcare professional to drain the blood. 

In all cases, when a nail is torn off, first wash the toe with water and soap. Then, ideally, apply an antiseptic product. After disinfecting, check if its base, also called the matrix, is damaged. It is a small white piece visible under the skin. If it is intact, the damage is likely superficial. If the matrix is also injured, you should quickly consult a healthcare professional to receive appropriate care. Otherwise, you may experience complications with nail regrowth. 

Can a Torn Toenail Be Saved?

You can avoid losing a torn nail if it still remains partially attached after the impact. It is usually recommended to monitor the injury’s progress and disinfect the wound daily.

How to Promote the Regrowth of a Toenail?

To ensure a traumatic nail grows back well, first disinfect the wound. If there is debris lodged in the wound, it should be removed. For a mild trauma, if a part of the nail is still attached and the matrix is not damaged, the nail can regrow without complications. 

If the nail is completely torn off, seeing a healthcare professional is essential if you want to restore your nail’s appearance. Without treatment, the nail may grow back with an unattractive shape or cause pain. 

Above all: be patient! A nail can take between 6 and 18 months to regain its appearance after trauma or tearing off.

Can the Appearance of a Fallen Nail Be Improved?

After losing a nail, the new nail may grow with a different appearance for several months. Depending on the trauma, the nail may become thicker, irregular, or deformed.

During regrowth, certain measures can help protect the toe and improve the nail’s appearance. However, it is best to avoid cosmetic products or fake nails until healing is complete to reduce the risk of irritation or infection.

If the nail remains painful or shows abnormal regrowth, a podiatrist can assess the situation and recommend appropriate treatments.

Yes. In many cases, the nail can regrow normally if the nail matrix was not damaged during the trauma. However, regrowth is slow. A toenail can take between 6 and 18 months to regain its usual appearance.

Frequently Asked Questions About a Torn Toenail

Can a Torn Toenail Regrow Normally?

Yes. In many cases, the nail can regrow normally if the nail matrix was not damaged during the trauma. However, regrowth is slow. A toenail can take between 6 and 18 months to regain its usual appearance.

Why Does the Nail Turn Black After a Blow?

After trauma, bleeding can occur under the nail. This phenomenon, called subungual hematoma, creates pressure that can cause pain and progressive detachment of the nail. In some cases, the nail eventually falls off a few days later.

Should a Partially Torn-Off Nail Be Removed?

Not necessarily. If part of the nail remains firmly attached and the injury seems superficial, sometimes it is better to leave the nail in place to protect the toe during healing. However, evaluation by a podiatrist can be helpful to avoid complications or infections.

Can Fake Nails Be Applied After Losing a Toenail?

It is preferable to wait until the toe has fully healed before applying a fake nail. Applying it too soon can increase the risk of irritation or infection, especially after a recent trauma.

What Signs May Indicate an Infection?

Significant redness, swelling, warmth around the toe, discharge, or increasing pain may indicate an infection. If these symptoms appear after nail trauma, it is recommended to consult a healthcare professional promptly.

Can You Continue Walking or Doing Sports After Losing a Nail?

It depends on the severity of the injury. A mild trauma sometimes allows fast resumption of activities. However, if the toe remains painful or sensitive to pressure, it may be better to limit some activities to promote healing and avoid worsening the injury.

When to Consult for a Torn Toenail?

Monitor your injury’s healing. A nail with edges that become painful, red, swollen, or warm indicates infection. In this case, to avoid spreading the infection, do not wait: make an appointment with a podiatry clinic that is part of PiedRéseau to receive personalized treatments promptly.
