Introduction The scope of examination of patients with closed intraarticular fractures of the calcaneus against the background of concomitant pathology has been discussed up to date. The aim of the study was to improve the accuracy of predicting the nature of postoperative wound healing after osteosynthesis of intra-articular fractures of the calcaneus from the extended lateral approach on the background of chronic obliterating diseases of the lower limb arteries of different etiology, smoking and a combination of these factors. Material and methods Sixty-nine patients who were smokers and/or suffered from chronic obliterating diseases with a total of 74 closed intra-articular fractures of the heel bones were analyzed. All patients received a comprehensive clinical and instrumental examination consisting of radiography and computed tomography of the calcaneus to determine the proximal-distal gradient (PDG), ankle-brachial index (ABI) and transcutaneous oximetry (TrOc). A single-factor analysis of variance was performed, after which an expert evaluation of the features was performed, as well as testing of models with different sets of signs. Results The disperse analysis of variance in respect of 74 cases for the relevant group of patients allowed us to obtain two models: the first with a level of statistical significance p0 < 0,001 (χ2 – 82,63; df = 7) and the predictive efficiency of 97.3 % in regard to possible complications after open reduction with internal fixation; the second level of statistical significance p0 < 0,001 (χ2 – 34,76; df = 7) and prognostic effectiveness of 93,24 % related to the risk of repeated surgical interventions. Conclusions The proposed method of predicting the development of complications in the immediate postoperative period after internal osteosynthesis of the calcaneus allows estimation of the risks of complications by calculating PDG, ABI and TrOc with high efficiency (97.3 %). The proposed discriminant model predicts the need for repeated surgical interventions with an efficiency of 93.24 %, and feasibility of surgical treatment with an extended lateral approach.

We investigated the safety and efficacy of debulking infrainguinal lesions in patients with peripheral artery disease (PAD) undergoing endovascular revascularization (EVR) as part of the RECording Courses of vascular Diseases (RECCORD) registry. Patient and lesion specific characteristics, including the lesion complexity score (LCS) were analyzed. The primary endpoint encompassed: (i) clinical improvement in Rutherford categories, (ii) index limb re-interventions, and (iii) major amputations during follow-up. The secondary endpoint included the need for bail-out stenting. Overall, 2910 patients were analyzed; 2552 without and 358 with debulking-assisted EVR. Patients were 72 (interquartile range (IQR) = 15) years old and 1027 (35.3%) had diabetes. Overall complication rates were similarly low in the debulking vs the non-debulking group (4.7 vs 3.2%, P = .18). However, peripheral embolizations rates were low but more frequent with debulking vs. non-debulking procedures (3.9 vs 1.1%, P < .001). After adjustment for clinical and lesion-specific parameters, including LCS, no differences were noted for the primary endpoint (odds ration (OR) = 0.99, 95%CI = 0.69–1.41, P = .94). Bail-out stenting was less frequently performed in patients with debulking-assisted EVR (OR = 0.5, 95%CI = 0.38–0.65, P < .0001). Debulking-assisted EVR is currently used in ∼12% of EVR with infrainguinal lesions and is associated with lower bail-out stent rates but higher peripheral embolization rates; no differences were found regarding index limb re-intervention and amputation rates.
