Accessory nail of the fifth toe is a common condition that affects the toenails of individuals. It is also known as the fifth toenail, subungual exostosis, or hypertrophied nail. This condition is characterized by the presence of an extra nail that develops either on the side of or underneath the fifth toenail. The extra nail can cause discomfort and pain to the affected individuals. In this article, we will define the term “accessory nail of the fifth toe” and discuss its types, causes, symptoms, diagnosis, and treatment options.
Definition:
An accessory nail of the fifth toe is an abnormal growth of an extra nail that develops either on the side of or underneath the fifth toenail. The extra nail can cause pain, discomfort, and inflammation to the affected individual. The accessory nail is usually smaller than the primary nail and may be partially or completely attached to the underlying bone. This condition is commonly seen in individuals who wear tight-fitting shoes or have a family history of the condition.
Types
There are two types of accessory nails of the fifth toe, which are as follows:
- Congenital: This type of accessory nail is present at birth and is caused by a genetic abnormality. Congenital accessory nails are often seen in individuals with a family history of the condition. The extra nail is usually attached to the underlying bone and can cause pain and discomfort.
- Acquired: This type of accessory nail develops over time due to trauma or injury to the toe. Acquired accessory nails are often seen in individuals who wear tight-fitting shoes or engage in sports activities that require repeated trauma to the toe. The extra nail may be partially or completely attached to the primary nail and can cause pain and inflammation.

Diagnosis
The diagnosis of accessory nails of the fifth toe typically involves a thorough physical examination of the affected foot, including a visual inspection of the toenail and surrounding skin. In some cases, additional diagnostic tests may be required to confirm the diagnosis, rule out other potential causes of toenail abnormalities, and determine the extent and severity of the condition. In this article, we will discuss 20 diagnostic tests that can be used to diagnose accessory nails of the fifth toe.
- Physical examination: The first step in diagnosing the accessory nail of the fifth toe involves a physical examination of the affected foot. The physician will inspect the toenail and surrounding skin for signs of hypertrophy, elongation, and thickening of the nail. The physician may also assess the patient’s gait and foot mechanics to determine if any underlying conditions, such as flat feet or overpronation, may be contributing to the development of the accessory nail.
- Patient history: The physician will ask the patient about their medical history, including any previous injuries or surgeries to the foot, as well as any family history of toenail abnormalities.
- X-ray: An X-ray of the foot can be used to assess the bony structures of the foot and determine if there are any underlying structural abnormalities that may be contributing to the development of the accessory nail.
- MRI: Magnetic resonance imaging (MRI) can be used to visualize the soft tissue structures of the foot and determine if there are any abnormalities in the surrounding tissues that may be contributing to the development of the accessory nail.
- CT scan: A computed tomography (CT) scan can provide a three-dimensional image of the foot and help identify any structural abnormalities that may be contributing to the development of the accessory nail.
- Blood tests: Blood tests can be used to rule out other potential causes of toenail abnormalities, such as fungal infections or systemic conditions like diabetes or thyroid disorders.
- Biopsy: A biopsy involves the removal of a small piece of tissue from the affected toenail or surrounding skin for laboratory analysis. This test can help identify the underlying cause of the accessory nail and rule out other potential causes.
- Nail clipping: Clipping a sample of the affected toenail can help identify any fungal infections or bacterial growth that may be contributing to the development of the accessory nail.
- Culture: A culture involves the collection of a sample of the affected toenail or surrounding skin and growing it in a laboratory to identify any fungal or bacterial growth that may be contributing to the development of the accessory nail.
- Histology: Histology involves the examination of a small piece of tissue from the affected toenail or surrounding skin under a microscope to identify any abnormal cells or tissue structures that may be contributing to the development of the accessory nail.
- Dermoscopy: Dermoscopy involves the use of a specialized tool to examine the surface of the toenail and surrounding skin for signs of hypertrophy, elongation, and thickening of the nail.
- Nail fold capillaroscopy: Nail fold capillaroscopy involves the use of a specialized microscope to examine the capillaries of the nail fold for signs of abnormal blood flow or structural abnormalities that may be contributing to the development of the accessory nail.
- Doppler ultrasound: Doppler ultrasound involves the use of sound waves to assess the blood
Treatment
Treatment options were available for the accessory nails of the fifth toe. These treatment options can be broadly divided into two categories: conservative measures and surgical interventions.
Conservative measures
- Observation: In some cases, the accessory nail may not cause any symptoms, and no treatment may be required. The patient may be advised to keep an eye on the condition and report any changes or discomfort to their healthcare provider.
- Nail trimming: Regular trimming of the accessory nail may help prevent ingrown nails, reduce pain, and improve the appearance of the affected toe. A healthcare provider or podiatrist can perform this procedure.
- Nail filing: Filing the accessory nail can smooth out any rough edges or irregularities and reduce pain and discomfort. A healthcare provider or podiatrist can perform this procedure.
- Soaking the affected toe in warm water: Soaking the affected toe in warm water can help reduce inflammation and pain. This can be done several times a day for 15-20 minutes at a time.
- Applying a topical ointment: Over-the-counter topical ointments containing antifungal or antibacterial agents may be applied to the affected toe to reduce the risk of infection and promote healing.
- Wearing open-toed shoes: Wearing open-toed shoes can help reduce pressure on the affected toe and promote healing.
- Wearing wider shoes: Wearing shoes with a wider toe box can help reduce pressure on the affected toe and reduce pain and discomfort.
- Wearing soft insoles or padding: Wearing soft insoles or padding can help cushion the affected toe and reduce pressure and pain.
- Oral medications: Oral medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to reduce pain and inflammation.
Surgical interventions
- Partial nail avulsion: This procedure involves removing a portion of the accessory nail or the entire nail plate. This can be done under local anesthesia in a podiatrist’s office.
- Total nail avulsion: This procedure involves removing the entire accessory nail and the nail bed. This is usually reserved for severe cases that have not responded to conservative treatment.
- Chemical cauterization: Chemical cauterization involves applying a chemical such as phenol to the nail bed to prevent the regrowth of the accessory nail. This is usually done after a partial nail avulsion procedure.
- Laser therapy: Laser therapy may be used to treat accessory nails that are thick or difficult to remove with traditional methods. The laser can vaporize the nail plate without damaging the surrounding tissue.
- Cryotherapy: Cryotherapy involves freezing the accessory nail with liquid nitrogen to destroy it. This is usually done after a partial nail avulsion procedure.
- Electrosurgery: Electrosurgery involves using an electric current to remove the accessory nail. This is usually done under local anesthesia.
- CO2 laser ablation: CO2 laser ablation involves using a CO2 laser to remove the accessory nail. This is usually done under local anesthesia.
