Injury to Toenail: Treatment Options for Pain and Discoloration - Dermatology

Nail injury due to compression by a heavy object?


Hello Dr.
Liao: A couple of days ago, my toenail (big toe) was crushed by a motorcycle.
The nail is not broken, but there is an internal wound, and the pus is trapped underneath the nail.
Additionally, there is a dent in the middle of the nail, with the front part appearing purple and the back half being red (darker than a normal nail).
What treatment should I pursue (do I need to have the nail removed)? Thank you!

Dr. Liao Wenyu reply Dermatology


These colors are likely indicative of subungual hemorrhage, which will gradually improve.
There should be no need to remove the nail.
If you have any concerns, please visit an outpatient clinic for evaluation.

More Info


Injuries to the toenail, particularly from trauma such as being crushed by a motorcycle, can lead to various complications, including pain, discoloration, and potential infection. Based on your description, it seems that you are experiencing a subungual hematoma (blood accumulation under the nail) and possibly an infection due to the presence of pus. Here’s a comprehensive approach to managing your condition:

Immediate Treatment Options
1. Assessment of Injury: First, it’s essential to evaluate the extent of the injury. Since you mentioned that the toenail is not completely severed but has a dent and discoloration, this indicates that there may be damage to the nail bed underneath. The purple discoloration suggests bruising, while the red area may indicate inflammation or infection.

2. Pain Management: Over-the-counter pain relievers such as acetaminophen or ibuprofen can help manage pain and reduce inflammation. Make sure to follow the recommended dosages.

3. Drainage of Accumulated Fluid: If there is significant pressure from blood or pus under the nail, it may need to be drained. This can often be done in a clinical setting. A healthcare professional can create a small hole in the nail to relieve pressure, which can provide immediate pain relief. This procedure is typically quick and can be done with local anesthesia.

4. Antibiotics: If there is a concern about infection (e.g., if there is pus), your doctor may prescribe antibiotics. It’s crucial to address any signs of infection promptly to prevent further complications.

5. Nail Care: Keep the area clean and dry. You can gently wash the toe with soap and water, then apply an antiseptic. Avoid soaking the toe in water, as this can exacerbate the risk of infection.


When to Consider Nail Removal
- Severe Damage: If the nail is severely damaged or if the nail bed is exposed, your doctor may recommend partial or complete nail removal. This is typically done under local anesthesia to minimize discomfort.


- Persistent Symptoms: If you continue to experience significant pain, swelling, or signs of infection despite conservative treatment, nail removal may be necessary to allow for proper healing and to prevent complications.


Follow-Up Care
- Monitor for Infection: Keep an eye on the injury for signs of infection, such as increased redness, swelling, warmth, or discharge. If these symptoms occur, seek medical attention promptly.

- Nail Growth: After the injury, it may take several months for the nail to grow back completely. The new nail may appear different in texture or color initially, but it should gradually return to normal.

- Avoiding Further Injury: Protect the toe from further trauma while it heals. Wearing open-toed shoes or sandals may help prevent additional pressure on the injured toe.


Conclusion
In summary, your injury requires careful monitoring and possibly intervention to relieve pressure and prevent infection. It’s advisable to consult with a healthcare professional for a thorough examination and to discuss the best course of action based on the severity of your injury. If drainage is necessary, it’s best performed by a qualified medical provider to ensure proper technique and minimize the risk of complications. Remember, timely intervention can significantly improve your recovery and reduce the risk of long-term issues with the toenail.
