Surgical repair of fracture of the os penis in a dog.

An eight-year-old male Australian cattle dog cross was presented with complete urethral obstruction secondary to fracture of the os penis which had occurred two years earlier. Obstruction was associated with callus and fibrous tissue proliferation compressing the urethra at the fracture site. The problem was satisfactorily resolved by removing excess bone and fibrous tissue and stabilising the fracture with a stainless steel finger plate.
