Management of laterally displaced proximal tibial physeal fractures in three dogs.

Fractures of the proximal tibial physis are uncommon in dogs, and are rarely associated with marked instability and lateral displacement of the proximal tibial epiphysis. Three dogs with proximal tibial physeal fractures demonstrating marked instability and lateral displacement were treated with two different principles of fixation. Healing of the physeal fracture was achieved with rigid internal fixation in one case, and with adaptational osteosynthesis supplemented with a temporary transarticular external skeletal fixator in two cases. Duration of surgery and technical difficulty was reduced using a modified adaptational osteosynthesis approach, suggesting that surgical treatment of these uncommon and challenging fractures may be more appropriately achieved by this technique.
