Radiological anatomy of the perforators of the gluteal region: The "radiosome" based anatomy.

The gluteal region is vascularized by perforators of multiple source arteries. Septocutaneous perforators of SGA and IGA were planned along a curve drawn from the posterior-superior border of the iliac crest to the greater trochanter. The lumbar artery perforators are clustered over the apex of the iliac crest; the internal pudendal artery perforators are clustered medially to the ischiatic tuberosity. Contributions can also come from the sacral and superficial circumflex iliac arteries.
