Pie charts demonstrating the distribution of minor and major wound complications for lower extremities, as well as the proportion of patients where no treatment regarding wound complications was needed (either no complication or patients with clinical or imaging finding where no treatment was needed). Most of the patients had either no complications or only imaging finding where no treatment was needed. Wound healing disorder was observed in 15 patients (38.5%). Conservative treatment was applied in 5/39 patients (12.8%), surgical treatment was needed in 10/39 patients (25.6%). In total, 7/39 patients had postoperative seroma (17.9%). A drainage or seroma aspiration was needed in 3/39 (7.7%) patients. Surgical intervention was needed in 4/39 (10.3%) patients (classified as major wound complication). Postoperative hematoma was documented in 2/39 patients (5.1%). Surgical treatment was performed in all patients with hematoma requiring intervention
