Anatomy of LOWER Limb Adductor Canal (Sub-sartorial Canal) (Hunter Canal) By Dr. Hassan Mohammed Rizk (Ph.D.) Associate Professor of Human Anatomy and Embryology  Case Study LOWER LIMB Sub-sartorial saphenous nerve block (SSNB) Adductor canal By Dr. Hassan Rezk October 5, 2024 2  Objectives: by the end of this lecture the student must understand the following knowledge: LOWER LIMB ▪ Identify and demonstrate the adductor canal, regarding: o Definition, Site & Shape. o Walls. o Roof. o Floor. o Contents and their arrangement. Adductor canal By Dr. Hassan Rezk October 5, 2024 3  Objective # ( 1 ) Adductor Canal – Definition, Site & Shape (Sub-sartorial Canal) (Hunter Canal) ▪ Definition & Site: is a long (approximately 15 cm), LOWER LIMB intermuscular passageway in the middle third of the thigh. ▪ Shape: Triangular in cross section. ▪ Extensions: ✓ from the apex of the femoral triangle. ✓ to the adductor hiatus in the tendon of the adductor magnus Adductor canal By Dr. Hassan Rezk October 5, 2024 4  Objective # ( 2 ) Adductor Canal – Boundaries (Sub-sartorial Canal) (Hunter Canal) LOWER LIMB Anteriorly and laterally: vastus medialis. Posteriorly (Floor): a) Adductors longus. b) Adductor magnus. Medially (Roof): a) sartorius. b) Fibrous membrane (vaso-adductor membrane).

Adductor 5) Descending genicular Longus artery (not present in this section) Adductor canal By Dr. Hassan Rezk October 5, 2024 8  Objective # ( 3 ) Adductor Canal – Contents & Arrangement (Sub-sartorial Canal) (Hunter Canal) Content Site LOWER LIMB Femoral artery Passes from upper end of the canal to lower end. Lower end of the canal: it lies posterolateral to the artery. Femoral vein Upper end of the canal: it lies posterior to the artery Enters through the upper end. Has a triple relation with femoral artery: -In upper 1/3 of canal: the nerve lies lateral to the artery. Saphenous nerve -In middle 1/3: Crosses in front of the femoral artery. -In lower 1/3: the nerve lies medial to the artery. ▪ Pierces the fibrous sheath in lower part to be superficial. ▪ Lateral to saphenous nerve in the upper part of the canal. Nerve to vastus medialis ▪ Leaves the canal by entering vastus medialis Originate from femoral artery at the lower part of the canal to supply the Descending genicular artery knee joint.

Adductor canal By Dr. Hassan Rezk October 5, 2024 12  Case Scenario A 25-year-old male presents with a history of sudden onset of severe pain in his right LOWER LIMB leg. On examination, there is a palpable pulsatile mass in the popliteal fossa. Doppler ultrasound confirms a popliteal artery aneurysm. Which of the following structures is more at risk to be compressed by the aneurysm in this case? A. Tibial nerve B. Common peroneal nerve C. Popliteal vein D. Sural nerve Adductor canal By Dr. Hassan Rezk October 5, 2024 13 LOWER LIMB Reference ISBN: 978-0-7020-5131-9 ISBN: 978-07817-7525-0 ISBN: 978-1-60913-446-4 Copyright© 2015, 2010, 2005 by Copyright© 2010, by Lippincott Copyright© 2012, by Lippincott Churchill Livingstone, an imprint of Williams & Wilkins, a Wolters Williams & Wilkins, a Wolters Elsevier Inc.
