[Rupture of the tibialis anterior tendon--a rare sports injury].

Rupture of the anterior tibial tendon is a very rare injury in sports. The rupture is based on degeneration of the tendon and caused by a forced plantarflexion. Main symptoms of this often "missed injury" are impossibility of dorsal extension of the foot and a palpable gap. The diagnosis can be confirmed by sonography or MRI. A complete healing can only be reached by operation. The reconstruction is done by tendon suture or distal refixation. Postoperative the ankle is immobilized in a cast for 6 weeks.
