title: Reconstruction of elbow region defects using radial collateral artery perforator (RCAP)-based propeller flaps.
abstract: Perforator-based propeller flaps permit flap rotation up to 180°. This ability to transfer skin from one longitudinal axis to another has led to the increasing use of perforator-based propeller flaps in extremity reconstruction, especially lower-extremity reconstruction. However, the application of perforator-based propeller flaps to upper-extremity reconstruction is still limited. This article reports two cases of successful reconstruction of elbow region defects with radial collateral artery perforator (RCAP)-based propeller flaps. The elbow region has a variety of perforators available for perforator-based propeller flap reconstruction. Among them, the RCAP seems to be one of the most reliable options. This is because there are less anatomical variations of perforators' location on the lateral upper arm than on the medial upper arm. By using an RCAP perforator as a flap pedicle, the small-to-medium sized defects (<6 cm in diameter) around elbow regions can be closed primarily without skin grafts.
