Definition
The fovea for ligament of head of femur is a roughened pit-like depression located below and lateral to the central region of the femoral head. It serves as the attachment point for the ligament of the head of the femur (a.k.a. ligamentum teres). The basal end of this ligament is affixed to the margins of the acetabular notch.
The ligament of the head of the femur acts as a conduit for arterial branches originating from the posterior division of the obturator artery and the ascending cervical branch of the medial circumflex femoral artery. These arterial branches (a.k.a. medial epiphyseal arteries) traverse through the acetabular notch and accompany the ligamentum teres in order to supply the medial portion of the femoral head.
