The sacroiliac joint is supplied primarily by the iliolumbar artery, which arises from the internal iliac artery. Additional blood supply comes from the lateral sacral and superior gluteal arteries, which also branch from the internal iliac artery. The inferior gluteal artery, a branch of the internal iliac artery, supplies blood to several structures, including the gluteus maximus muscle, parts of the hip joint, and nearby muscles like the piriformis, obturator internus, and superior hamstrings. It also contributes to the arterial supply of the sciatic nerve.
