Background.Diabetic foot ulcers (DFUs) represent one of the most severe late-stage complications of diabetes.Tibial cortex transverse transport (TTT) surgery stands as the prevailing method for addressing DFUs.This surgical intervention holds the promise of expediting DFU wound healing and diminishing the rate of amputations, with the mitigation of inflammatory responses playing a pivotal role.In this study, we aim to explore the correlation between inflammation and TTT surgery, with the overarching goal of facilitating swift prognostic assessments in clinical practice. Objectives. The correlation between the severity of DFUs and clinical test results remains ambiguous.A clinical prediction model was devised to explore the connection between DFU severity and the efficacy of TTT surgery, utilizing straightforward and efficient clinical indicators. Materials and methods.Clinical data and examination results were gathered by tracking hospitalized DFU patients who underwent TTT surgery at the First Affiliated Hospital of Guangxi Medical University (Nanning, China).Indicators associated with DFU severity and wound healing time post-surgery were identified through logistic regression and least absolute shrinkage and selection operator (LASSO) regression analyses.Subsequently, a clinical prediction model was constructed.Finally, the intersection of these 2 sets of indicators revealed factors correlated with wound severity and post-operative healing duration. Results.Our study was comprised of 202 patients who were categorized into 2 groups based on Wagner's grading classifications.Utilizing Student's t-tests, LASSO regression and logistic regression analyses, we identified 3 factors indicative of DFU severity: platelet-to-lymphocyte ratio (PLR), mixed lymphocyte reaction (MLR) and hemoglobin (HGB).Univariate COX regression analysis revealed 12 factors such as: white blood cells (WBC), neutrophils (NEUT), monocytes (MO), PLR, MLR, neutrophil-to-lymphocyte ratio (NLR), erythrocyte sedimentation rate (ESR), age, lymphocytes (LY), monocyte-to-neutrophil ratio (MNR), uric acid (UA), and albumin (ALB) associated with the postoperative healing duration.Ultimately, we identified 2 factors, PLR and MNR, at the intersection of these 2 datasets.Conclusions.Platelet-to-lymphocyte ratio and MNR were identified as factors associated with both the severity of DFUs and the prognosis following TTT surgery.
