Will My Mom's Toenail Grow Back After Injury? Expert Advice Needed

Hello, Dr. Gao: I would like to ask you some questions regarding nails. Thank you?

Hello, Doctor Gao: My mother's big toe nail was stepped on, and blood is continuously oozing from under the nail.
She had a previous injury about 20 years ago, where the nail fractured approximately 2 to 3 millimeters above the nail bed.
Currently, we are rinsing it with saline solution, applying eye ointment around the nail, and protecting it with a breathable bandage.
Will the nail grow back? Is there a better way to manage this, or should we see a doctor for treatment?

Dear Roro,
Hello.
Self-treatment may lead to issues with wound healing or infection, and the management must take into account the patient's overall condition.
Please make sure to visit a general surgery outpatient clinic as soon as possible.
Wishing you safety and health.

In response to your question regarding whether your mom's toenail will grow back after injury, it is important to understand the healing process of toenails and the factors that can influence their regrowth.

When a toenail is injured, especially if there is bleeding under the nail (a condition known as a subungual hematoma), it can lead to significant pain and may affect the nail's ability to grow back properly. The toenail grows from the nail matrix, which is located under the cuticle at the base of the nail. If the nail matrix is damaged during the injury, it can result in abnormal nail growth or even permanent loss of the nail.

In your mom's case, since she has experienced bleeding from the nail and has a history of previous injury to the same toenail, there are a few considerations to keep in mind:
1. Nail Regrowth: If the nail matrix is intact and not severely damaged, the toenail will likely grow back. However, it may take several months for the nail to fully regrow, as toenails typically grow at a rate of about 1 millimeter per month. Given that your mom's injury occurred recently, it may take time before you see significant regrowth.

2. Infection Prevention: It is crucial to keep the area clean and protected to prevent infection. You mentioned using saline solution and antibiotic ointment, which is a good initial approach. However, if there are signs of infection (such as increased redness, swelling, warmth, or pus), it is essential to seek medical attention promptly.

3. Medical Evaluation: Given the nature of the injury and the history of a previous injury to the same toenail, it would be advisable for your mom to see a healthcare professional. A doctor can assess the extent of the injury, check for any damage to the nail matrix, and provide appropriate treatment. They may also need to drain any accumulated blood under the nail if it is causing significant pain.

4. Follow-Up Care: After the initial treatment, it is important to monitor the nail as it grows back. If the nail appears to be growing back abnormally or if there are ongoing issues with pain or infection, further evaluation may be necessary.

5. Home Care: In addition to keeping the area clean, you can help your mom by ensuring she avoids tight footwear that may put pressure on the injured toe. Elevating the foot can also help reduce swelling.

In summary, while there is a good chance that your mom's toenail will grow back if the nail matrix is intact, it is essential to monitor the injury closely and seek medical evaluation to ensure proper healing and prevent complications. If you have any concerns about her condition or if the injury worsens, do not hesitate to consult a healthcare professional for further advice and treatment.
