Abstract

Background: Managing complex soft tissue defects remains a major challenge in orthopedic trauma and reconstructive surgery. Negative Pressure Wound Therapy (NPWT), or Vacuum-Assisted Closure (VAC), has significantly improved wound care by reducing edema, stimulating granulation tissue, and controlling infection. However, conventional NPWT systems have limitations in large tissue defects or when external fixation is required. The CNP Easy-dress system, a controlled 3D negative pressure dressing, was developed to overcome these shortcomings. Thi study evaluates the clinical efficacy, safety, and applicability of the CNP 3D Easy-dress system in managing complex soft tissue defects.

Methods: This case series includes four patients with extensive soft tissue defects, three of whom required external fixation. All patients were treated with NPWT using the CNP 3D Easy-dress system at the Center for Orthopedic Trauma and Plastic Surgery, Hue Central Hospital, starting from September 2024.

Results: All patients showed rapid improvement of soft tissue and robust granulation tissue formation after an average of 2–4 dressing changes. Subsequent wound coverage was successfully achieved with skin grafts or free flaps, with no complications such as infection or flap failure.

Conclusion: The application of the CNP 3D Easy-dress system enhances the effectiveness of NPWT in the management of complex soft tissue defects, particularly in cases requiring external fixation. This method shortens treatment duration, minimizes complications, and improves postoperative functional recovery.
