title: [Ligamentous injuries to the ankle joint].
abstract: Injuries to the lateral ankle ligaments are the most common sports injuries. Determination of their severity and exclusion of relevant accompanying injuries requires a subtle clinical and a focussed radiological assessment. Treatment is non-operative and functional in the majority of cases. Consequent application of orthoses limiting supination and proprioceptive training are essential to avoid chronic instability. With recurrent ankle sprains one has to distinguish between functional and mechanical instability. The latter can be treated successfully with anatomic reconstruction and ligamentoplasty in more than 80 % of cases. Extraanatomic tenodeses should be reserved for cases of combined ankle and subtalar instability. Isolated injuries to the medial collateral ligaments are rare. Therefore, osseous injuries or underlying deformities have to be excluded. Isolated deltoid ligament ruptures may be treated non-operatively. Unstable injuries to the distal tibiofibular syndesmosis resulting in a manifest or latent diastasis are treated with open reduction and fixation with two tibiofibular set screws. Anatomic reduction of the distal fibula into the tibial groove is of utmost prognostic relevance and therefore should be reliably proved with either intraoperative 3D fluoroscopy or postoperative CT scanning. For chronic syndesmotic instability an anatomic ligamentoplasty using half the peroneus longus tendon is recommended.
