The tibialis posterior muscle originates from the interosseous membrane and adjacent tibial posterior surface in the proximal third of the leg.The tendon forms in the dis-tal third of the leg and lies closely apposed to the tibia posteromedially.Distally, the posterior tibialis tendon sits in a medial or posterior concavity on the medial edge of the posterior tibia.Just lateral to the posterior tibialis tendon lies the flexor digitorum tendon.The posterior tibialis tendon curves distally around the medial malleolus.It is at this level that the tendon lies beneath the flexor retinaculum, which prevents the flexor tendons from bowstringing as they curve around the malleolus [9].
