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 and weak arch control 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]
Assessment[edit | edit source]
Assessment of Muscle strength[5]:
Treatment[edit | edit source]
Strengthening:[edit | edit source]
Strengthening will also improve the arch control of the foot.
