Orthotic Devices and Nail Bracing Flashcards

The Onyfix nail correction system works by:

Answer: Applying a composite compound along the nail surface that hardens and uses the nail's own growth to correct curvature

Onyfix uses a UV-cured composite applied across the nail; as the nail grows, the brace's spring tension progressively flattens the nail curvature without invasive procedures.

How often are most nail braces replaced or adjusted?

Answer: Every 4–8 weeks, coinciding with nail growth

Nail brace treatment cycles of 4–8 weeks align with toenail growth; regular re-assessment allows the clinician to evaluate correction progress and adjust tension.

A custom-molded silicone orthosis for a clawed toe is designed to:

Answer: Provide cushioning for the tip of the toe and/or dorsal surface, preventing pressure ulceration

Clawed toes develop high-pressure points at the tip and dorsum; custom silicone orthoses protect these vulnerable areas from shoe friction and pressure.

When applying a wire brace (e.g., VHO Goldstadt), the wire is anchored by:

Answer: Hooking into small notches or holes filed/drilled at the lateral nail edges

Wire braces anchor at the lateral nail edges via notches or holes; tension in the wire creates an outward spring force that corrects nail curvature.

Patient education after nail brace placement should include:

Answer: Keeping the brace dry, avoiding swimming and prolonged water immersion, and returning if brace loosens

Water immersion weakens adhesive bonding; patients should be instructed to keep braces dry and report early loosening to prevent loss of corrective tension.

Plantar fascitis management with orthotics primarily aims to:

Answer: Provide medial arch support and heel cushioning to reduce tension on the plantar fascia insertion

Orthotics for plantar fasciitis support the medial arch to prevent excessive pronation and provide heel cushioning, reducing the mechanical strain at the calcaneal fascia attachment.
