Abstract

Introduction: Traumatic spinal cord injuries are damage to the spinal cord tissue caused by traffic accidents, falls (local trauma), and violent trauma, specifically from firearms, cutting, or blunt force trauma. Regenerative therapy with mesenchymal stem cells and the use of exosomes have shown promising results, with functional recovery. Objective: To describe the clinical, functional, and neurological course of a patient with a partial cervical spinal cord injury treated with combined regenerative therapy. Methods and results: This is a descriptive case report study. We present the case of a 42-year-old patient with trauma and spinal cord injury from C4 to C7 who, after treatment in two doses with stem cells, exosomes, platelet-rich plasma, and ozone, showed neurological and functional improvement, as well as improvement in his pressure ulcers. Conclusion: Improvement in functional status and ulcer healing was observed following treatment with stem cells and exosomes. These findings support the need for clinical trials and objective clinical characterization of patients in order to strengthen the scientific foundation for the development of these therapies.
