Antibiotic-loaded Bone Cement Combined with Vacuum-assisted Closure Facilitating Wound Healing in Wagner 3-4 Diabetic Foot Ulcers

This study explored the clinical effectiveness of antibiotic-loaded bone cement (ALBC) combined with vacuum-assisted closure (VAC) on the treatment of Wagner 3-4 diabetic foot ulcers (DFUs). This is a retrospective study, including 32 patients with Wagner 3-4 DFUs who had undergone treatment between August 2019 and June 2021. Patient age, sex, Hemoglobin A1c (HbA1c), body mass index (BMI), ankle brachial index (ABI), white blood cells (WBC), C-reactive protein (CRP) levels, comorbidities and wound closure methods were recorded. Patients were divided into the study group and control group according to the treatment modality. Patients in the study group received the combination treatment of ALBC and VAC, while patients in the control group received single VAC treatment. Clinical endpoints were assessed and compared between the two groups, including wound complete healing time and complications after operation. All patients were followed-up 6 months postoperation. Results showed that the mean healing time of the study group (44.20 ± 16.72 days) was shorter than that of the control group (64.00 ± 29.85 days) (P < .05). The infection rate of the study group on the 10th day postoperation was lower than that of the control group (6.67%, 47.06%, P < .05). And there were no significant statistical differences between the two groups in terms of bleeding and necrosis complications postoperation (P = .603, P = .603). Based on the findings, we conclude that the application of ALBC combined with VAC can facilitate wound healing in Wagner 3-4 DFUs patients. It can help to control wound infections and shorten wound healing time.
