An eight-year-old male Australian cattle dog cross was presented with
complete urethral obstruction secondary to fracture of the os penis wh
ich had occurred two years earlier. Obstruction was associated with ca
llus and fibrous tissue proliferation compressing the urethra at the f
racture site. The problem was satisfactorily resolved by removing exce
ss bone and fibrous tissue and stabilising the fracture with a stainle
ss steel finger plate.
