Use of Local Flaps for Soft-Tissue Closure in Diabetic Foot Wounds: A Systematic Review

"A systematic review was undertaken to assess the outcomes of local random flaps in diabetic foot wound closure. The review was conducted using the following databases: Cumulative Index of Nursing and Allied Health Literature, Cochrane Library, Excerpta Medica dataBASE, Google Scholar, MEDLINE, Ovid, and PubMed. Search terms were local random flap, diabetes, foot, wound, ulceration, neuropathy, tissue transfer, V-Y, bilobed, monolobed, rotational, advancement, transpositional, rhomboid, and Limberg. English language studies, studies published from 1997 to 2017, patients with diabetes mellitus treated for foot wounds, use of local random flaps, follow-up period of 6 months or more postoperatively, documentation of healing rates, complications, and need for revisional surgery were included. Isolated literature reviews and descriptions of only surgical technique and/or cadaveric studies were excluded. The initial search identified 53 eligible studies with 28 being excluded. The remaining 25 studies used for data extraction had a total of 512 patients in which 199 of these underwent 204 local random flap procedures. Average follow-up for the flaps was approximately >2 years, and successful wound closure at last follow-up was demonstrated in 75.5% of the studied population. Studies were found to be of generally low quality, with the majority composed of retrospective case series. Based on current available evidence found in this systematic review, local random flaps demonstrated a relatively high success rate when utilized for the definitive closure of diabetic foot wounds. However, because of a lack of high-quality evidence and substantial heterogeneity among the studies, the results should be interpreted with caution. Levels of Evidence: Level III: Systematic review.
