The tibialis posterior has a major role in supporting the medial arch of the foot. Dysfunction of the tibialis posterior, including rupture of the tibialis posterior tendon, can lead to flat feet in adults, as well as a valgus deformity due to unopposed eversion when inversion is lost. [4] [5]
Posterior tibial tendon dysfunction is the dysfunction of the posterior tibial tendon. It is a progressive disease that has four stages [ 1 ] and is the most common cause of adult flatfoot . [ 2 ]
Accessory navicular bone may cause a continuous stretch and stress on the tibialis posterior tendon which can progress to chronic disabling pain and may cause tendon rupture or secondary flat foot deformity; when this occurs this condition is commonly known as accessory navicular syndrome. [4]
If non-invasive treatment measures fail, tarsal tunnel release surgery may be recommended. Tarsal tunnel release is a form of a nerve decompression to relieve pressure on the tibial nerve. The incision is made behind the ankle bone and then down towards but not as far as the bottom of foot. The posterior tibial nerve is identified above the ankle.
McCormick later learned what was nagging him: two screws put in to fix the previous fracture were rubbing on his posterior tibial tendon, and it resulted in a complete tear of the tendon. Debra ...
The flexor hallucis longus is situated on the fibular side of the leg. It arises from the inferior two-thirds of the posterior surface of the body of the fibula, with the exception of 2.5 cm at its lowest part; from the lower part of the interosseous membrane; from an intermuscular septum between it and the peroneus muscles, laterally, and from the fascia covering the tibialis posterior, medially.
It is composed of a thin muscle belly and a long thin tendon. While not as thick as the achilles tendon, the plantaris tendon (which tends to be between 30–45 centimetres (12–18 in) in length) is the longest tendon in the human body. Not including the tendon, the plantaris muscle is approximately 5–10 centimetres (2.0–3.9 in) long and ...
The tibial nerve, posterior tibial artery, posterior tibial vein, and flexor tendons travel in a bundle along this pathway through the tarsal tunnel, in the following order from anteromedial to posterolateral: Tibialis posterior tendon. [2] Flexor digitorum longus tendon. [2] Posterior tibial artery. [2] Posterior tibial vein. [1] Tibial nerve. [2]
