Ascending Branch of Lateral Circumflex Femoral Artery (Left)

Origin

An ascending branch arises from the lateral circumflex femoral artery, close to the lesser trochanter.

Course

The ascending branch of the lateral circumflex femoral artery travels posterior to the tensor fasciae latae muscle, then travels upward along the intertrochanteric line.

Branches

The ascending branch of the lateral circumflex femoral artery gives retinacular branches that supply the head of the femur.

It contributes to the anastomoses with the superior gluteal artery, the deep circumflex iliac artery, and thus, contributes to the vascularization of the greater trochanter of the femur.

It also anastomoses with the medial circumflex femoral artery to complete an anastomotic ring around the femoral neck, contributing to the vascularization of the head and neck of the femur.

Supplied Structures

The ascending branch of the lateral circumflex femoral artery contributes to the supply of the proximal femur, including the head and the neck, and the vascularization of the hip joint.
