Non-Contact Low-Frequency Ultrasound Vs Standard LaLonde Protocol for Fingertip Injury Wound Healing

Enhancing Healing With Non-Contact Low-Frequency Ultrasound in Fingertip Amputation Treatment: A Prospective Comparative Cohort Study

Who can join

Ages 18 and older · All sexes

Inclusion Criteria:

* Individuals aged 18 years or older with an acute traumatic fingertip amputation without exposed bone or tendons (Allen 1, Tamai level 1; ICD-10 codes S68.5 and S68.6).

Exclusion Criteria:

* Patients less than 18 years old,
* Injuries involving exposed bone
* Those with diagnosis of vascular disease
* Individuals with clinical suspicion or diagnosis of infection
* Unable to comply with prescribed therapy sessions
* Patients undergoing primary closure or surgical intervention
* Patients experiencing subsequent trauma following treatment initiation

About the study

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.
