A fascial canal extending from the apex of the femoral triangle to the adductor hiatus. Its other names include Hunter’s canal, or the subsartorial canal. The adductor canal is approximately 15cm long.
Anterolateral = vastus medialis
Posteromedial = adductor longus and adductor magnus
Anteromedial (roof) = subsartorial fascia
Nerve to vastus medialis
Aperture in the lower end of adductor magnus muscle
As the femoral artery exits the adductor canal via the adductor hiatus, it becomes the popliteal artery, which runs through the popliteal fossa.
Adductor canal block
Use of local anaesthetic to block the saphenous nerve only using its location in the adductor canal.
For procedures to the distal thigh, knee and medial side of leg
A pure sensory block
Can be combined with a sciatic block to provide a complete sensory block to the distal thigh, knee, leg and foot.
Adductor canal compression syndrome
Rare, but most common in young men
Compression of the neurovascular bundle within the adductor canal
Causes = hypertrophy of adjacent muscles, abnormal musculotendinous band
Symptoms and signs often appear during exercise and include: calf claudication, paraesthesia, oedema, absent pedal/popliteal pulses, pain
