Popis: This is a purely observational study with a literature comparison to assess the effectiveness of radial and ulnar arteries propeller perforator-based flaps in post-traumatic soft tissue reconstruction and identify the risk factors for complications. Sixteen patients were involved with post-traumatic wrist and hand soft tissue defects not exceeding 5 × 20 cm. Defects were covered with propeller radial and ulnar arteries perforator-based flaps. Patient demographics, soft tissue defects, complications and clinical outcomes were recorded. Assessment of patients’ satisfaction for donor site morbidity and aesthetic outcome of the flap were performed. Radial artery propeller perforator flap was performed in seven cases, and ulnar artery propeller perforator flap was done in nine cases. The size of the skin paddle ranged from 2.5 × 5 cm to 4.5 × 10.5 cm. Primary closure of the donor site was performed in all cases. One flap was lost, while superficial epidermolysis occurred in seven cases (45%). Edge necrosis ranging between 3 and 7 mm occurred in nine cases (60%). Patients’ factors, mode of injury, associated injuries and interval between trauma and coverage were all correlated with complication incidence. The patients’ satisfaction for donor site morbidity was very good and good in 80% of patients, while satisfaction for aesthetic outcome of the flap was very good and good in only 40%. Radial and ulnar arteries have reliable perforators for flap elevation, which produce reliable outcome for small- and medium-sized soft tissue reconstruction. Effectiveness decreases in post-traumatic reconstructions. Complications are more frequent in crushing injuries especially if associated with bony fractures. Most complications in trauma cases were attributed to venous congestion, for which supercharging with a vein if accessible to the surgeon is recommended.
