- 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;
