Lower limb
Adductor canal, adductor hiatus, and femoral canal
Canalis adductorius, hiatus adductorius et canalis femoralis
- Origin
- Adductor canal (Hunter's canal: fascial tunnel in the middle third of thigh bounded by vastus medialis, adductors, and sartorius); Femoral canal (medial compartment of femoral sheath)
- Insertion
- Terminates at the adductor hiatus within the adductor magnus tendon leading into the popliteal fossa
- Function
- Provides safe conduit for femoral vessels and saphenous nerve transitioning from anterior thigh to popliteal fossa
- Innervation
- Perivascular and saphenous nerve fibers
- Movement & chain
- Dynamically adapted to adductor and quadriceps muscular contractions
- Palpation
- Deep anatomical space beneath sartorius muscle
- Clinical
- Adductor canal syndrome (arterial/nerve compression in young athletes); Femoral hernia (strangulation risk through femoral ring in elderly females)
- Segmental innervation
- L2–L4 spinal segments
- In clinical practice
- Ultrasound-guided Adductor Canal Block (ACB) for knee arthroplasty analgesia; emergency surgical repair for incarcerated femoral hernia
