This paper aims to describe a new type of proximal antebrachial fracture-dislocation lesion. A cli- ent-owned, 5-year-old male, intact, 28kg Golden retriever is the case of this paper. The fracture was repaired with a 4-holed standard 3.5 reconstruction plate and screws. However, this fixation caused an iatrogenic lengthening of the radius and secondary elbow incongruity and prevented the reduction of the ulna into its place. Therefore, a dynamic ulnar osteotomy and ulnar IM pining were performed to release plate-caused tension on the elbow joint. After the splinted bandage removal the dog had weight-bearing lameness, but gradually improved over time. The owner report- ed that the dog had intermittent lameness for a few minutes right after waking up on some days. A slight soft tissue thickening and the periosteal reaction were determined on the 4th and 6th-week evaluations. The joint range of motion values (extension and flexion) was slightly lower than the healthy side. Monteggia fracture describes a specific lesion of the proximal antebrachium, no other specific fracture-sub/luxation lesion of the proximal antebrachium has been described in humans and animals. Therefore, the patient with a proximal radial fracture and ulnar luxation/subluxation can be considered a new type of proximal antebrachial lesion.
