Ultrasound Therapy for Finger Amputation

This trial tests a new method to heal fingertip amputations using non-contact low-frequency ultrasound therapy. Researchers aim to determine if this method improves recovery compared to the standard treatment of cleaning and bandaging the wound. Participants will be randomly assigned to receive either ultrasound therapy or the standard treatment, with therapy sessions occurring a few times a week. The trial seeks individuals who have recently experienced a fingertip amputation without exposed bone or tendons. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could enhance healing methods for future patients.

The trial information does not specify whether you need to stop taking your current medications.

Earlier studies have shown promising results with non-contact low frequency ultrasound. Participants reported fewer issues, such as disruptions in daily activities and sensitivity to cold, compared to those using other methods. However, limited information exists about potential side effects or negative reactions, so further research is needed to understand its safety in humans. The treatment applies a gentle ultrasound mist to the wound, a method safely used in other wound care types. Since this study does not focus on in-depth safety testing, monitoring for new information or findings is important.¹²³⁴⁵

Unlike the standard of care for finger amputation, which usually involves basic wound management techniques like rinsing and wrapping, the non-contact low-frequency ultrasound (NCLF-US) therapy introduces a new approach using ultrasound energy delivered through a sterile water mist. This method is unique because it potentially enhances healing by stimulating tissue repair and reducing inflammation without direct contact with the wound. Researchers are excited about this treatment because it could speed up recovery and improve healing outcomes compared to traditional methods.

This trial will compare non-contact low-frequency ultrasound therapy with the Lalonde protocol for treating fingertip amputations. Studies have shown that non-contact low-frequency ultrasound can speed up healing in fingertip amputations compared to traditional methods. Specifically, one study found that a treatment called UltraMIST helped fingertip injuries heal nine times faster than the usual Lalonde method. This ultrasound therapy uses sound waves and a mist to aid healing without touching the wound. It likely works by improving blood flow and reducing swelling and irritation. These early findings suggest that non-contact low-frequency ultrasound could be a promising new option for people with fingertip amputations.¹⁶⁷⁸⁹
