Description
This is an inflammation of the posterior tibial tendon. Physical
examination usually reveals tenderness at the navicular insertion
or just behind the medial malleous along the tendon. In younger
patients this is caused by an overuse of the posterior tibialis or
relative weakness of this muscle. The posterior tibial tendon is
the primary inverter of the foot. It is one of the primary supports
of the medial longitudinal arch. By pointing the sole of your foot
towards the midline of your body you are using the posterior tibial
tendon.
This being said, when the foot pronates excessively the post. Tib.
Tendon is stressed and placed on a stretch. Excessive pronation must
be controlled. Post. Tib. Tednonitis can lead to PTTD (Posterior
Tibial Tendon dysfunction) and in advanced cases a Posterior
Tibial Tendon Rupture. In these advanced cases foot orthotic
therapy is much more aggressive. In the most severe cases an
Arizona A.F.O. (Ankle Foot Orthosis) may be used. An A.F.O. uses
the lower leg as leverage to stabilize the mid foot, taking the
place of the Posterior Tibial Tendon. In older patients, posterior
tibial tendonitis is caused by degeneration of the tendon and is
less responsive to conservative treatment. A custom calf stretching
and strengthening of the posterior tibialis are often prescribed
with tendonitis. Physical therapy may be beneficial. Surgery is often
used as a last resort.
