[Fracture of the tibial head].

Fractures of the tibial head are severe injuries, characterized by enormous variety. Fractures can be classified into fractures of the tibial plateau, luxation fractures, and comminuted fractures. Due to the mechanism of injury luxation fractures are frequently associated with lesions of the menisci and intra- and extra-articular ligaments. Multiple factors can be etiologic for post-traumatic gonarthrosis: nonanatomic reduction of the joint surface, malalignment, and unaddressed associated injuries. Therefore in addition to diagnostic steps such as X-ray, CT scan, and MRI a sophisticated therapeutic regime is necessary. In cases with severely damaged soft tissue or unstable patients, the fracture should initially be reduced and fixed with an external fixator and the definite fixation should be performed in a second setting. Arthroscopically assisted treatment is reserved for fractures of the tibial eminence, crack fractures, and impression fractures. Comminuted and bilateral fractures can be addressed via different incisions. New locking plates with angular stability allow avoidance of bilateral plating in most situations. In specific cases such as compound fractures and for patients with low compliance, a hybrid fixator may be a well-chosen alternative.
