Three immature cats with growth abnormalities of the distal radius secondary to trauma were presented between July 2001 and July 2003. Initial injuries included a Salter-Harris type II fracture of the distal radial physis in one cat, fractures of the styloid process of the ulna in two cats, and metacarpal fractures in one cat. The cats were between 3.5 and 4.5 months of age at the time of injury. Damage to the distal radial physis resulted in a variable degree of shortening of the radius in all cats. Asymmetrical closure caused widening of the lateral aspect of the radiocarpal joint space in two cats. Elbow incongruity was not observed. One cat was treated with osteotomies of the radius and ulna and realignment of the radius, stabilised with external skeletal fixation. Another was treated by ulnar ostectomy alone. Radius and ulna osteotomies and distraction osteogenesis of the radius were performed in the third cat. Clinical outcome was satisfactory in all three cases.
