Nonviable nonunions of radius and ulna were treated with the cortical bone allograft, cancellous bone autograft and the topical application of fibroblast growth factor-2 (FGF-2) in two toy Poodles. After the debridement of the noviable segments, cortical bone allografts were transplanted into the bone defects and were fixed with the reconstruction plate. In addition, cancellous bone autografts and FGF-2 were applied in these cases to stimulate bone healing. After confirmation of bone union with radiographs, some of the bone screws were removed to increase the axial load on the grafts. Finally all bone screws and bone plates were removed without any complications. The results obtained in these cases suggest that the combination of cortical bone allograft, cancellous bone autograft and topical application of FGF-2 is effective for the treatment of the nonviable nonunion.

Non-union or delayed-union is common complication in small animal orthopedics. Recent studies shows bone marrow contains mesenchymal stem cells, which enhance bone regeneration to differentiate into osteoblasts. In this study, auto-transplantation of bone marrow-derived mesenchymal stromal cells (BMSCs) was performed for delayed-union cases of a cat (Japanese cat, 4 months) and a dog (toy poodle, 8 months) and evaluated radiologically. BMSCs were aspirated from femur, expanded and transplanted around the fracture at 1, 2, 3 weeks after the re-operation. In each case, callus union was observed until 2 months. These results suggested that BMSCs transplantation might be effective for delayed-union cases.

A 9-month old 3.2 kg of body weight, male Chihuahua was presented with a history of the intermittent vomiting for two days. Abdominal radiograph showed a foreign body in abdominal cavity which was suggested to be a micro battery in small intestine. Although the dog was treated symptomatically for two days, physical condition of the patient worsened, therefore exploratory laparotomy was performed. A large adhesive lesion involved the perforated ileum and large intestines, was found. A micro battery was stuck in the ileum resulting in a intestinal perforation. A whole of the small intestine was resected because of the cranial mesenteric artery damage during separating the adhesion. The dog lost body weight gradually and died 158 days after first admission of short bowel syndrome.
