The Lacuna Method
(Nail Fenestration)
An effective, minimally invasive treatment for fungal nails

Fungal nails can be persistent, unsightly, and difficult to treat using standard topical treatments. At AA Podiatry, we offer The Lacuna Method, an advanced technique that involves creating tiny, painless holes in the nail plate. This approach allows antifungal medication to reach the source of the infection more effectively by delivering it directly to the nail bed, where the fungus lives and spreads.
What causes the problem?
Fungal nail infections are typically caused by dermatophyte fungi, which thrive in warm and moist environments like the inside of shoes. The infection often starts as a white or yellow spot under the nail and can gradually spread, causing the nail to become thickened, brittle, crumbly, and discoloured.
Is it serious?
While fungal nails are usually not dangerous, they can be stubborn and unsightly. If left untreated, the infection may spread to other nails or the skin (athlete’s foot), and in some cases, cause pain or discomfort when walking. For people with diabetes or circulation issues, fungal nails can increase the risk of secondary infections, making early treatment important.
How does the treatment work?
The Lacuna Method, also known as nail fenestration, is a painless and innovative technique that involves creating multiple micro-holes in the affected nail plate. These holes:
​
-
Allow anti-fungal solution to reach the nail bed directly .
-
Help break down the fungal environment and stop the infection from spreading.
-
Enable better penetration and redistribution of medication with the pressure of footwear.
Over time, the healthy nail grows out naturally, along with the holes. Review appointments are typically recommended every 6 weeks, though your podiatrist will tailor this to your needs.
When should I see a podiatrist about it?
Consider booking an appointment if you notice any of the following:
​
-
Discolouration (white, yellow, brown, or black spots) on the nail
-
Thickening, flaking, or crumbling nails
-
Nails separating from the nail bed
-
Discomfort when wearing shoes or walking
-
Previous treatments (e.g., creams or oral medication) haven’t worked
​
Early intervention can prevent the infection from worsening or spreading. The Lacuna Method offers a non-invasive alternative for patients seeking a more effective approach to fungal nail treatment.
