Study Details

Brief summary:

The goal of this clinical trial is to compare the efficacy of non-contact low frequency ultrasound in populations sustaining fingertip amputations. The main question it aims to answer is:

• Does non-contact low frequency ultrasound significantly improve patient outcomes in patients sustaining acute fingertip amputations?

Researchers will compare non-contact low frequency ultrasound to a standard Lalonde protocol to answer this questions.

Participants will be randomized one of the two study arms and evaluated by wound care therapy. They will receive cohort appropriate therapy sessions 2-3 times per week with measurement of wound size once per week.

Interventions and Outcome Measures

Arms

experimental: Non-Contact Low Frequency Ultrasound

Lalonde therapy and non-contact low-frequency (UltraMIST) therapy - NCLF-US therapy involves delivering low-frequency (40 kHz), low-intensity (0.1-0.8 W/cm2) ultrasound energy via sterile water mist.

active comparator: Lalonde Protocol

Standard of care local wound therapy using the Lalonde protocol - rinsing the site with clean water, applying a grease layer, wrapping with a one-inch gauze wrap, and securing with Coban tape.

Interventions

Lalonde Protocol (standard of care)

Standard of care local wound therapy using the Lalonde protocol - rinsing the site with clean water, applying a grease layer, wrapping with a one-inch gauze wrap, and securing with Coban tape.

Primary outcome measure

  • Wound Dimensions (mm2) [ Time Frame: Assessed weekly. From date of randomization through study completion (an average of 8 weeks) ]
  • Time to Healing (days) [ Time Frame: From randomization through study completion (an average of 8 weeks) ]
