Posterior tibial artery

The posterior tibial artery (latin: arteria tibialis posterior) is a continuation of the popliteal artery as one of its terminal branches.

The posterior tibial artery passes through the cruropopliteal canal, then it passes behind the medial malleolus and below the flexor retinaculum. On the plantar surface the posterior tibial artery divides into its terminal branches: the lateral and medial plantar arteries.

The posterior tibial artery gives off several side branches:

  • medial plantar artery,
  • lateral plantar artery,
  • peroneal artery,
  • circumflex fibular artery,
  • muscular branches,
  • malleolus medial arteries,
  • tibial nutrient artery,
  • calcaneal branches.

The posterior tibial artery supplies blood to the posterior compartment of the lower leg and to the plantar surface of the foot.
