Freestyle perforator-based propeller flap of medial arm for medial elbow reconstruction

Elbow reconstruction is challenging for reconstructive surgeons. The purpose of this report is to present the results of the use of freestyle perforator-based propeller flap designed from the medial arm region for elbow reconstruction. The defects following soft tissue sarcoma resection at the medial and posterior elbow were repaired in two patients. The dimensions of the defects were 11 × 7 cm(2) and 10 × 7 cm(2). Two perforators were identified in each case using Doppler ultrasound probe in the medial arm, adjacent to the defect. The perforator with visible pulsation was chosen as the pedicle vessel, which was 12-cm and 7-cm proximal to the medial epicondyle. An elliptical flap, extending almost the full length of arm, was raised and rotated 180° to repair medial elbow defects. The sizes of the flaps were 17 × 8 cm(2) and 11 × 7 cm(2). The donor sites were closed directly. Both flaps survived; temporary venous congestion occurred in one case. There were no other postoperative complications. These cases illustrated that the medial arm flap might be used for reconstruction of medial elbow defects with this freestyle perforator-based propeller flap design.
