==Introduction==

==Introduction==

The tibial crest is the insertion point for the '''straight patellar tendon''' and it forms as a '''separate centre of ossification'''. Hyperflexion of the stifle joint can cause avulsion of the growth plate of the tibial crest in '''immature animals''', less than about 10 months of age.

It can occur in cats and dogs, and the Greyhound and Terrier breeds are overrepresented.

'''Radiography''' provides a definitive diagnosis. Lateral and craniocaudal views are usually all that is necessary.

There is a normal radiolucent line between the tubercle and the tibit prior to fusion of the tubercle, and this should not be mistaken for a fracture.

The tibial tubercle will be displaced proximally if it is avulsed.

In unilateral cases it may be helpful to '''compare with radiographs of the contralateral side'''.
