Background <p>Diabetic foot ulcers (DFUs) represent a common and serious complication of diabetes mellitus, often progressing to infection, necrosis, and possible limb amputation. Conventional management strategies, including systemic antibiotics and corticosteroids, frequently fail to achieve full wound resolution.</p> Case presentation <p>We report a case involving a patient with a necrotic DFU. The patient underwent surgical debridement followed by application of ovine forestomach matrix (OFM) as a regenerative treatment. OFM was chosen for its ability to promote tissue regeneration and support wound healing in chronic, non-healing wounds.</p> Intervention <p>Post-debridement, the wound site was treated with OFM in a controlled clinical setting. No additional systemic antimicrobial or steroidal interventions were applied after the initiation of OFM therapy.</p> Outcome <p>The application of OFM led to marked tissue regeneration, significant pain reduction, and progressive wound closure. Notably, complete wound healing was achieved without the need for limb amputation.</p> Conclusion <p>OFM appears to be an effective regenerative therapy in the management of necrotic DFUs, offering a viable alternative to traditional treatments and reducing the risk of amputation.</p>
