Ascending Cervical Branches to the Hip

- Discussion:
    - ascending cervical branches arise from extracapsular arterial ring;
    - anteriorly, they penetrate capsule of hip joint at intertrochanteric line;
    - posteriorly, they pass beneath the orbicular fibers of capsule;
    - ascending cervical branches may be divided into 4 br;
         - anterial, medial, lateral, posterior;
         - of these lateral provides most of blood supply to femoral head;
         - at margin of of articular cartilage on surface of the neck of femur, these vessels form second ring;
              - subsynovial intra articlar ring
