[The rupture of the tibial anterior tendon in a world class veteran fencer].

The rupture of the tendon of the M. tibialis ant. is a rare sport injury and has not been yet described in fencing. The lunge, the most common offensive movement in fencing, displays a high stress on the spanned tendons and ligaments over the ankle joint and led to the rupture of the pre-damaged tendon of our patient. Pain over the inner side of the foot should be assessed as knells of this tendon injury. The exact patient's history and the precise clinical investigation are adequate for diagnosing the rupture. Hereby, an absence of the tendon shape over the ankle joint and a distinct active deficit of the extension are presented in comparison to the other side where a gap in the tendon course is palpable. An x-ray is obligate, a sonography and a MRI are helpful for the operative planning. The surgical treatment is necessary for athletes. If possible, a primary tendon suture should be aimed, in case of a distal torn an osseous reinsertion should occur. An early functional, postoperative treatment with an orthesis should be rather preferred for athletes than an immobilization.
