Introduction
A plicatured nail is a common but often misunderstood nail disorder that can cause discomfort and cosmetic concerns. This condition occurs when the nail plate curves inward, pinching the nail bed and surrounding skin. If left untreated, a plicatured nail can lead to pain, inflammation, and even infection.
In this comprehensive guide, we’ll explore the causes, symptoms, and effective treatment options for it. Whether you’re experiencing this condition or simply want to learn more, this article will provide valuable insights.
What Is a Plicatured Nail?
it (also known as a “folded nail” or “involuted nail”) is a deformity where the edges of the nail curve downward, digging into the adjacent nail folds. Unlike an ingrown toenail, where the nail grows into the skin, it involves an exaggerated curvature of the nail plate itself.
This condition most commonly affects the toenails, particularly the big toe, but it can also occur in fingernails. People with naturally curved nails or those who wear tight footwear are more prone to developing it.
Causes of Plicatured Nails
Several factors contribute to the development of a plicatured nail, including:
1. Genetic Predisposition
Some individuals inherit naturally curved or thickened nails, making them more susceptible to plicatured nails.
2. Improper Nail Trimming
Cutting nails too short or rounding the edges can encourage the nail to grow into the skin, worsening the curvature over time.
3. Tight Footwear
Shoes that squeeze the toes can put pressure on the nails, forcing them to curl inward. High heels and narrow-toe boxes are common culprits.
4. Trauma or Injury
Stubbing a toe or dropping something heavy on the foot can damage the nail matrix, leading to abnormal nail growth.
5. Aging
As we age, nails tend to thicken and lose elasticity, increasing the likelihood of developing a plicatured nail.
6. Fungal Infections
Onychomycosis (nail fungus) can distort the nail structure, causing excessive curvature.
Symptoms of a Plicatured Nail
Recognizing the signs of a plicatured nail early can help prevent complications. Common symptoms include:
- Pain and tenderness along the nail edges
- Redness and swelling around the affected nail
- Difficulty wearing shoes due to pressure on the nail
- Thickened or discolored nail plate
- Bleeding or discharge if an infection develops
- Ingrown nail-like discomfort, but with a more pronounced curve
If left untreated, a plicatured nail can lead to chronic inflammation or paronychia (nail infection).
Diagnosis of Plicatured Nails
A podiatrist or dermatologist can diagnose a plicatured nail through a physical examination. In some cases, they may take a nail sample to rule out fungal infections or recommend imaging (like an X-ray) if bone involvement is suspected.
Treatment Options for Plicatured Nails
The treatment approach depends on the severity of the condition. Here are the most effective methods:
1. Conservative Treatments
For mild cases, non-surgical options may help:
- Proper Nail Trimming: Cut nails straight across (not rounded) to reduce inward pressure.
- Wearing Wider Shoes: Opt for footwear with a spacious toe box to minimize compression.
- Soaking the Nail: Warm Epsom salt soaks can reduce inflammation.
- Antibiotic Ointments: If infection is present, topical antibiotics may be prescribed.
2. Nail Bracing
A specialized brace or wire can be applied to gently lift the nail edges, correcting the curvature over time.
3. Cotton or Dental Floss Insertion
Placing a small piece of cotton or dental floss under the nail edge can help lift it slightly, reducing pressure on the skin.
4. Partial Nail Removal (Partial Avulsion)
For persistent cases, a doctor may remove the curved portion of the nail under local anesthesia. The nail typically regrows normally if the root (matrix) is preserved.
5. Permanent Correction (Matrixectomy)
In severe or recurrent cases, a minor surgical procedure called a matrixectomy may be performed. This involves removing a portion of the nail matrix to prevent the problematic section from regrowing.

Preventing Plicatured Nails
Prevention is key to avoiding the discomfort of a plicatured nail. Follow these tips:
✅ Trim nails straight across – Avoid rounding the edges.
✅ Wear properly fitted shoes – Choose footwear with enough toe space.
✅ Maintain good foot hygiene – Keep feet clean and dry to prevent infections.
✅ Address nail trauma promptly – Seek treatment for injured nails to prevent deformities.
✅ Avoid repetitive pressure – Limit activities that put excessive stress on the toes.
When to See a Doctor
If you experience severe pain, signs of infection (pus, foul odor), or if home remedies don’t improve the condition, consult a healthcare professional. Early intervention can prevent complications.
Conclusion
A plicatured nail can be a painful and persistent issue, but with proper care and treatment, it can be managed effectively. Understanding the causes, recognizing symptoms early, and following preventive measures are crucial steps in maintaining healthy nails.
If you suspect you have a plicatured nail, don’t ignore it—seek professional advice to avoid long-term problems. With the right approach, you can restore comfort and keep your nails in optimal condition.
FAQs About Plicatured Nails
Q1: Is a plicatured nail the same as an ingrown toenail?
No, an ingrown toenail occurs when the nail edge grows into the skin, while a plicatured nail involves excessive curvature of the nail plate itself.
Q2: Can plicatured nails heal on their own?
Mild cases may improve with proper nail care, but severe cases often require medical intervention.
Q3: How long does it take to recover from nail surgery?
Recovery typically takes 2-4 weeks, depending on the procedure.
Q4: Are plicatured nails contagious?
No, they are not contagious unless caused by a fungal infection.
Q5: Can I prevent plicatured nails if they run in my family?
Yes, by following proper nail care and wearing well-fitted shoes, you can reduce the risk.
