Case Study: Application of Class 4 Laser Therapy in Treating Tail Crushing Injury in a Dog

Introduction

Tail crushing injuries are common traumatic soft tissue injuries in canine clinical practice, often caused by heavy objects, door pinches, or accidental compression. These injuries typically result in severe tissue contusion, subcutaneous hematoma, inflammatory edema, and intense pain. Without timely intervention, they can lead to wound infection, delayed healing, or even necrosis requiring amputation.

Class 4 laser therapy serves as an advanced, non-invasive physical therapy in veterinary medicine, offering significant anti-inflammatory and healing-promotion effects. This report documents the complete recovery of a dog with a severe tail contusion caused by a falling object using VETMEDIX (FotonMedix) equipment, providing a clinical reference for managing similar traumatic injuries.

05 Case Summary

Short-term Recovery: The veterinary team at Hangzhou Songzi Pet Hospital implemented a targeted Class 4 laser therapy protocol. During the treatment cycle, localized swelling and subcutaneous congestion gradually dissipated. Symptoms of acute pain and inflammatory redness were effectively relieved. The wound surface dried and began to scab, significantly reducing the patient’s discomfort during daily activities.

Long-term Follow-up: Regular follow-up visits confirmed that the tail injury had completely healed. The scabs shed naturally, and the skin returned to its smooth, original state. No complications such as skin adhesion, excessive scar hyperplasia, secondary infection, or tissue contracture were observed. The dog has returned to a healthy and comfortable lifestyle.

Conclusion: This case proves the significant clinical value of VETMEDIX small animal high-power laser therapy in treating blunt force tail injuries. Utilizing Photobiomodulation (PBM) technology, deep tissue laser therapy acts non-invasively on the injured site to improve local blood circulation, alleviate edema, and accelerate tissue repair, offering a superior clinical advantage for trauma management.
