A quantitative method for measuring forces applied by nail braces.

Area of Science:

• Podiatry
• Biomechanics
• Dermatology

Background:

• Ingrown nail management often relies on conservative nail bracing.
• Objective measurement of forces applied by nail braces is lacking.
• This limits the standardization of treatment for diverse nail presentations.

Purpose of the Study:

• To objectively measure the forces exerted by double-string nail braces with metal springs.
• To investigate the relationship between nail characteristics and applied force.
• To explore the potential for standardizing ingrown nail brace treatment.

Main Methods:

• Applied double-string nail braces with metal springs to 21 ingrown nails in 12 patients.
• Measured applied force using a force gauge meter.
• Assessed treatment endpoint by patient's ability to walk pain-free without braces.

Main Results:

• All patients achieved pain relief after 6-10 months of treatment.
• Applied forces ranged from 600 to 1,000 centi Newtons.
• Increased nail width correlated with higher applied force.

Conclusions:

• Nail braces apply greater force to wider nails, potentially reducing treatment time.
• Measuring applied forces may allow for treatment standardization based on nail variables.
• Objective force measurement can guide personalized ingrown nail treatment protocols.
