42-A3   Simple transverse tibial fracture

42-A3 fractures

42-A3 are simple transverse fractures of the tibial diaphysis. (Fracture angle >60° relative to the long axis of the bone).

definition

General considerations

The tibia has an S-shape in the frontal plane. In the sagittal plane, cat tibias are straighter than in dogs. Even though this will not influence the fracture fixation method, it is important to bear it in mind when reconstructing the fracture and restoring the normal anatomy.

definition

The fibula at the level of the tibia midshaft is very thin. For this reason, fractures of the fibula are generally not addressed.

definition

Etiology

42-A type fractures generally result from low energy trauma.

Clinical signs

Clinical signs observed in 42-A fractures are:

  • Swelling of the region
  • Abnormal movement in the tibia shaft
  • Pain

Cats with A1 type fractures may present with mild to severe non-weight bearing lameness. Cats with incomplete fractures may still be able to use the limb.

Imaging

Craniocaudal and lateral radiographic views are needed.
