ADDUCTOR CANAL6 HUNTER'S CANAL OR SUBSARTORIAL CANAL)DEFINATIONThe adductor canal is an aponeurotic point tunnelSituated in the middle 1/3rd of the thigh. ItExtends from femoral triangle to the opening in theadductor magnus.SYNONYMHunter's Canal or Subsartorial Canal.SITEIt is an intermuscular passage situated on the medialSaronius muscle.aspect of the middle 1/3 of the thigh undercover theRAYSHAPETriangular in transeverse section.BEGINNINGAbove, at the apex of femoral triangle (whereENDsartorius and adductor longus overlapped).Below, at the opening in adductor magnus(adductor hiatus)Continuous with the poplical fossaUpto the 5th Oscio- aponeurotic opening by becomingBOUNDARIESANTEROMEDIAL WALL (ROOF)Human Annuary For Exam(1) Sartorius Muscle (2) Strong sheet deep fascia (Steething betweenvastus medialis & addustor magnus)ANTEROLATERAL WALLFormed by vastus medialis Muscle.POSTERIOR WALL(1) In Upper part :- Adductor longus muscle(2)In lower part:- Adductor magnus muscle ADDUCTOR CANAL2CONTENTSHuman Anaromy For FramA2 Structures enter the upper end of the canal and leave itthrough its end -1Femoral Antery.
