Description[edit | edit source]
The Tibialis Posterior is located deep in the posterior compartment of the lower leg and situated between the Flexor Digitorium Longus and the Flexor Hallucis Longus. It is a key stabilising muscle supporting the medial arch of the foot.
Origin[edit | edit source]
The origin of the muscle is[1]:
Proximal postero-lateral aspect of the tibia.
Proximal postero-medial aspect of the fibula and the interosseous membrane
Mid portion: Situated in the deep posterior compartment of the lower leg and runs proximal to the medial malleoli where it is secured by the flexor retinaculum.
Insertion[edit | edit source]
The major insertion is onto the navicular and the plantar slip attaches to the medial cuneiform bone[1].
Nerve[edit | edit source]
Artery[edit | edit source]
Function[edit | edit source]
To plantarflex and invert the ankle. It also plays an important role in stabilising the medial longitudinal arch. Tibialis posterior dysfunction can lead to flat feet in adults.
Clinical relevance[edit | edit source]
- Tibialis Posterior Tendon Dysfunction (TPTD) is thought to be the likely cause in most cases of adult acquired flatfoot[3]
- In foot drop (High steppage gait) as a result of deep peroneal nerve palsy, transferring the posterior tibialis tendon to the dorsum of the foot is a surgical tendon transfer procedure carried out to compensate for the loss of dorsiflexion due to tibialis anterior paralysis.[4]
