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.
基于穿支的桨形皮瓣可旋转 180°。这种将皮肤从一个纵轴转移到另一个纵轴的能力，导致基于穿支的桨形皮瓣在手外重建，特别是下肢重建中的应用越来越多。然而，基于穿支的桨形皮瓣在手外重建中的应用仍然有限。本文报告了两例成功应用桡侧副动脉穿支（RCAP）为蒂桨形皮瓣修复肘部区域缺损的病例。肘部有多种穿支可供穿支桨形皮瓣重建。其中，RCAP 似乎是最可靠的选择之一。这是因为在外侧上臂，穿支位置的解剖变异比在内侧上臂要少。通过使用 RCAP 穿支作为皮瓣蒂，可直接闭合肘部周围小至中等大小的缺损（<6cm 直径），而无需植皮。
