case_images: One year later, the tumor recurred, and the patient underwent a second surgery after neoadjuvant therapy with chemotherapy and radiotherapy (Figure 1).
case_images: Intraoperative photographs of the patient in Case 1. (A) After extensive resection of the tumor, a large soft tissue defect, which exposed the radius, was observed. (B) While preserving the radial nerve, a 19 x 6.5 cm reverse lateral upper arm flap was raised. (C) The radius was covered with a flap, and a mesh skin graft was performed on a portion of the skin where the forearm muscle was exposed.

case_images: A 19 x 6.5 cm reverse lateral upper arm flap was implanted for extensive soft tissue defects (Figure 2).
case_images: Case 1: Range of motion in the forearm and elbow 8 years and 3 months after the operation. (A) Degree of extension. (B) Degree of flexion.

case_images: Eight years and three months postoperatively, the extension of the elbow was 0 , flexion was 140 , and International Society of Limb Salvage score was 27 points, which indicated adequate function preservation in the elbow and forearm (Figure 3).

case_images: Radiographs of the patient in Case 2. (A) Radiograph taken immediately after the injury. The arm and elbow were contaminated with several windshield pieces. (B) Radiograph taken after debridement. The white arrow indicates deficient humeral condyles, while the black arrow indicates radial head defects.

case_images: Figure 4 shows an X-ray image obtained at the time of the injury.
case_images: Intraoperative photographs of the patient in Case 2. (A) A 20 x 7 cm reverse lateral upper arm flap was designed. (B) The donor site was closed primarily. (C) One year and 5 months after flap implantation.

case_images: Two days after the injury, the extensive soft tissue defects were covered with a 20 x 7 cm reverse lateral upper arm flap (Figure 5).

case_images: Intraoperative photographs of the patient in Case 3. (A) A 17 x 7 cm reverse lateral upper arm flap was designed. (B) The forearm and the elbow at the time of primary closure of the donor site. (C) Five months after flap implantation.

case_images: A 17 x 7 cm reverse lateral upper arm flap was implanted for the extensive soft tissue defects (Figure 6(a)). The donor site was temporarily sutured (Figure 6(b)); however, after suturing, the pulsation of the radial artery disappeared, and all fingers turned pale. Five months after the surgery, the healing process was uneventful (Figure 6(c)).
