Avulsion of the tibial tuberosity with separation of the proximal tibial physis in seven dogs.

Seven dogs developed avulsions of the tibial tuberosity apophysis in combination with a fracture of the proximal tibial physis. Six of them were small terrier breeds, treated by internal fixation using two Kirschner wires and a tension band in five cases, and crossed Kirschner wires alone in the other. The seventh case was managed conservatively. The tension band repair was simple, provided adeqate fixation and avoided the placement of implants across the proximal tibial physis.
