Background: Undermining ulcers often require invasive treatments, such as skin incision, debridement, negative pressure wound therapy, and occasionally flap surgery.Sorbact , an antimicrobial dressing, has demonstrated efficacy in wound infection control; however, its use in treating undermining ulcers has rarely been reported.This study aimed to evaluate the effectiveness of Sorbact Compress in promoting wound closure of ulcers with undermining without invasive procedures.Methods: We retrospectively reviewed the treatment outcomes and complications in patients with undermining ulcers treated with Sorbact alone between July and November 2024.Results: The mean age was 71.2 years.The ulcer locations were the head (one case), abdomen (two cases), buttock (one case), and lower leg (one case).One patient developed postoperative wound dehiscence, while the other four progressed to ulcer formation following infection.The total ulcer size was < 5 cm in all cases.Wound closure was achieved in four of the five cases.Undermining resolved within an average of 6 weeks, with three cases showing a noticeable reduction within 2-3 weeks after intervention.In one case, deep heterotopic ossification impeded healing, leading to the discontinuation of the procedure.No procedure-related complications were observed during the follow-up.Conclusions: Successful closure of undermining ulcers with Sorbact alone appears feasible under the following conditions: absence of residual foreign bodies, necrotic tissue, or infection requiring debridement; infection as the primary cause of delayed wound healing; total ulcer size 5 cm; and simple pocket morphology.Careful patient selection makes this a viable treatment option.
