Anatomy
Course
This is the smallest branch from the lateral circumflex femoral artery. It travels laterally to pierce the vastus lateralis muscle. It then joins with the medial circumflex femoral artery contributing to the anastomosis around head of the femur.
Supply
The transverse branch of the lateral circumflex artery supplies the head and neck of the femur, as it anastomoses with the medial circumflex artery.
Clinical
The lateral circumflex artery and its branches are clinically relevant as it forms part of the cruciate anastomosis. Should a blockage arise between the internal iliac artery and the femoral artery, blood can reach the knee and lower leg via the cruciate anastomosis.
