[Tendinitis of the foot].

Tendinitis in the ankle and foot is frequent. It is due to overwork, relative senescence or rheumatoid inflammation. Damages are graded from isolated lesions of the sheath to rupture of the tendon. The diagnosis, at least anatomical, is facilitated by the superficiality of the tendons and by good anatomico-functional knowledge. Treatment rules cannot really be established. Surgery should remain wide open. The foot should always be the best static and dynamic conditions, and this can be achieved by possible plantar ortheses and by the quality of footwear.
