Presentation
Presents with chronic fracture and shoulder luxation after being stuck in a baby gate 8 weeks previously. The leg has been splinted.
Patient Data
There are transverse fractures of the proximal diaphysis of the right radius and ulna. There is mild lateral and moderate caudal displacement of the distal fracture segments. The fracture margins are rounded and there is mild periosteal proliferation associated with the fractures indicative of chronicity. There is marked osteopenia with thinned cortices and radiolucency of the antebrachium, distal humerus and manus.
Delayed union fracture and osteopenia.
Case Discussion
Delayed union often occurs in fractures with excessive motion, infection, or in animals with reduced capacity to form callus including older animals. Although toy breeds are affected, a recent large study did not find them to be at increased risk of delayed union or non-union.
