Branch Circumflexus Fibulae of the Posterior Tibial Artery (Ramus Circumflexus Fibulae, Pna)

The circumflex fibula branch of the posterior tibial artery (Ramus Circumflexus Fibulae, Pna) is one of the branches of the tibial artery located in the lower part of the leg. It is a small artery that starts from the tibial artery and bends around the fibula in the back of the leg.

This branch of the artery is usually quite small and has a fairly limited distribution in the human body. However, it plays an important role in providing blood supply to the muscles and bones in the back of the leg.

The circumflex fibular branch of the posterior tibial artery is one of the key arteries that supplies blood to the muscles and bones in the lower leg and foot. It supplies blood to the muscles that control movement of the foot and toes, as well as to the skin on the foot and lower leg.

In addition, the circumfibular branch of the posterior tibial artery is an important artery for foot and ankle surgery. Surgeons often use this artery to graft bone and tissue into the area.

Thus, the circumfibular branch of the posterior tibial artery plays an important role in providing blood supply to the muscles and bones in the leg and foot, and is also an important artery for surgical interventions in this area.
