Adductor hiatus

Last revised by Andrew Murphy on 27 Oct 2022

The adductor hiatus is an opening between the adductor magnus muscle and the femur. It is also known as the hiatus magnus.

Gross Anatomy

  • adductor hiatus represents the distal end of the adductor canal

  • it is the anatomical landmark where the femoral artery and vein transition to become the popliteal artery and vein, respectively

Clinical Significance

Supracondylar femoral fractures can result in femoral and/or popliteal artery damage and subsequent impairment of lower limb blood supply 1.

The majority of femoropopliteal occlusions occur at the adductor hiatus 2. One uncommon example of this is popliteal artery entrapment syndrome, which causes lower limb claudication and ischemia secondary to popliteal artery compression 3.
