The study aimed to develop a computational fluid dynamics-based mobile wound irrigation education program and explore changes in irrigation pressure control, wound irrigation-related knowledge and performance confidence in syringe-based wound irrigation. This study used a single-group pre–post design. A computational fluid dynamics-based mobile wound irrigation program was developed following the Analysis, Design, Development, Implementation, and Evaluation model. The program enabled learners to manipulate irrigation variables and visualize pressure distribution in real time. Thirty-four participants were recruited. Irrigation pressure was measured using a load cell-based device, and knowledge and performance confidence were assessed pre- and post-intervention. Data were analysed using paired t-tests and content analysis. The mean irrigation pressure increased significantly, although the post-intervention mean remained below the recommended pressure range and the proportion of participants achieving the recommended range rose from 0% to 44%. Knowledge and performance confidence also improved significantly. Qualitative findings indicated enhanced understanding of performance standards, improved technical awareness and reduced uncertainty during skill execution. Participation in the computational fluid dynamics-based mobile education program was associated with improvements in irrigation pressure control, related knowledge and performance confidence in syringe-based wound irrigation. These findings should be interpreted as preliminary because of the single-group pre–post design. Numerical visualization and real-time feedback may be useful educational strategies for facilitating the transition from experience-based skill performance to data-driven practice.

To investigate whether micronized acellular dermal matrix (mADM) can be used to treat diabetes-related and traumatic foot wounds with bone defects after bone or joint resection. We retrospectively reviewed 52 patients who underwent bone or joint resection, followed by mADM-assisted reconstruction of diabetes-related or traumatic foot wounds between 2021 and 2024. mADM was applied using sheet-type, paste-type or combined formulations in one- or multi-stage procedures. Wound healing, contour preservation and radiological alignment were assessed. Among the 52 patients (43 with diabetes and 9 with trauma), complete epithelialization was achieved in 48 (mean follow-up: 14.8 months; mean time to wound closure: 5.6 weeks). Four cases showed recurrence or delayed healing and five developed mild early local infection; all were controlled with additional wound care or antibiotics, with no progressive osteomyelitis or graft loss. In 40 radiologically evaluable cases, the toe length and alignment were generally preserved (mean toe length ratio: 91.6% and no angular deformity > 10°). mADM-assisted reconstruction may be useful for treating diabetes-related and traumatic foot wounds with bone defects after bone or joint resection. Its role appears to lie in dead-space management, contour preservation and durable wound coverage, rather than bone replacement.
