Q

Where does the Posterior Tibial Artery bifurcate? and What does it bifurcate into?

A
  1. Bifurcation occur in the tarsal tunnel2. The Posterior tibial artery splits into the Lateral and Medial Plantar Arteries- The tibial nerve also follows this pattern (Splits into the Medial and Lateral Plantar Nerves)

Q

What is the name of the condition characterized by an enlarged common plantar nerve? And what causes this?

A
  1. Morton’s Neuroma2. As the patient enters the “push off” phase of walking the interdigital nerve is sandwhiched between the ground and the transverse metatarsal ligament which compresses the common plantar nerve.
