Blood supply to femoral head:

-major contributor is medial femoral circumflex (lateral epiphyseal artery)

-some contribution to anterior and inferior head from lateral femoral circumflex

-some contribution from inferior gluteal artery

-small and insignificant supply from artery of ligamentum teres

-displacement of femoral neck fracture will disrupt the blood supply and cause an intracapsular hematoma (effect is controversial)
