Enlarged and hypertrophic nails, classified under ICD-10 code Q84.5, refer to conditions where the nails become abnormally thickened or enlarged, often leading to discomfort and functional issues. The management of this condition typically involves a combination of medical, surgical, and supportive treatment approaches. Below is a detailed overview of standard treatment strategies for this condition.

Understanding Q84.5: Enlarged and Hypertrophic Nails

Definition and Causes

Enlarged and hypertrophic nails can result from various factors, including:
- Genetic predisposition: Conditions like nail dystrophies can be hereditary.
- Trauma: Repeated injury to the nails can lead to thickening.
- Infections: Fungal infections are a common cause of nail thickening.
- Systemic diseases: Conditions such as psoriasis or eczema can also affect nail health.

Standard Treatment Approaches

1. Medical Management

Medical treatment often focuses on addressing underlying causes and alleviating symptoms.

a. Topical Treatments

• Antifungal agents: If a fungal infection is present, topical antifungals (e.g., ciclopirox, efinaconazole) may be prescribed to reduce nail thickness and treat the infection[1].
• Keratolytics: Agents like urea or salicylic acid can help soften and thin the nail plate, making it easier to manage[2].

b. Systemic Treatments

• Oral antifungals: In cases of severe fungal infections, systemic antifungal medications (e.g., terbinafine) may be necessary[3].
• Corticosteroids: For inflammatory conditions like psoriasis, systemic or intralesional corticosteroids can reduce inflammation and improve nail appearance[4].

2. Surgical Interventions

When conservative treatments fail or if the condition is severe, surgical options may be considered.

a. Nail Avulsion

• Partial or total nail avulsion: This procedure involves the removal of part or all of the affected nail. It is often performed under local anesthesia and can provide significant relief from pain and discomfort associated with hypertrophic nails[5].

b. Matrixectomy

• Nail matrix excision: In cases where the nail growth is severely abnormal, excising the nail matrix (the tissue under the nail that produces the nail) may be performed to prevent the regrowth of the abnormal nail[6].

3. Supportive Care

Supportive measures can enhance treatment outcomes and improve patient comfort.

a. Footwear Modifications

• Proper footwear: Wearing shoes that provide adequate space for the toes can help alleviate pressure on the nails, reducing pain and discomfort associated with hypertrophic nails[7].

b. Regular Nail Care

• Trimming and filing: Regularly trimming and filing the nails can help manage thickness and prevent further complications. Patients may be advised to seek professional pedicure services if self-care is challenging[8].

4. Follow-Up and Monitoring

Regular follow-up appointments are essential to monitor the condition and adjust treatment as necessary. This is particularly important for patients with underlying systemic conditions that may affect nail health.

Conclusion

The management of enlarged and hypertrophic nails (ICD-10 code Q84.5) involves a multifaceted approach tailored to the underlying cause and severity of the condition. Medical treatments, surgical interventions, and supportive care play crucial roles in alleviating symptoms and improving nail health. Patients experiencing this condition should consult with a healthcare provider for a comprehensive evaluation and personalized treatment plan to ensure optimal outcomes.
