Das wird dich sicher interessieren, Monika:

In einem Artikel von Montavon und Tepic, in dem sie u.a. auf die Entwicklung der TTA eingehen, findet sich folgender Passus:

"Early complication rates of a few per cent have caused no alarm. In most cases complications were related to technical errors, such as placement of the implants and location/orientation of the osteotomy."

du bist genial :lach2: den kannte ich noch nicht, danke

so um dem thema mal ein paar neue aspekte zu geben *g*

I have found that 12 mm cages really only belong in dogs over 55 kg. If the

The entire surgery is based on the tibial tuberosity as the landmark. This means that the first hole of the tension band plate goes just behind the tuberosity. The fork appears to be placed appropriately. The cranial hole of the cage should be behind the first hole of the tension band plate, such that the cage is about 4 mm distal from the top of the tibial plateau. The screw in the caudal hole breaks when there is too much torque on it, try aiming the screw more cranially without binding the long digital extensor tendon.

Someone has been teaching the procedure and telling folks to place the cage level with the joint. I disagree with this. It leaves the cage under excessive stress at a point where it can in fact rock back and forth. Placing it more distally allows the force of weight bearing to secure the cage better. In fact, I have had no broken screws since placing the cage the aforementioned 4 mm distal from the joint surface.

erstaunlicher weise keine einzige antwort aus deutschland, zürich und niederlande, aber mehrere amerikanische spezialisten haben ehrlich! geantwortet also doch zumindest deutschland, zürich und nl "götter in weiß". das ist die best erklärteste, darum nur diese.

ich hatte doch recht das es am einbau liegt :)

Du hast verschiedene TTA-Spezialisten angeschrieben?

Neugierig, Grazi
