Fractures of the proximal fifth metatarsal that are distal to the tuberosity require more aggressive treatment. This includes fractures of the metaphyseal-diaphyseal junction (Figure 5) and fractures of the diaphysis (Figure 6). Complications such as delayed union and nonunion are common.
Extramedullary spinal tumors are far more common than intramedullary tumors. The most common extramedullary spinal tumors are meningiomas and schwannomas and they are both generally benign tumors. Meningiomas arise from arachnoid cells within the tissues of the spinal cord.
Mast Cell Tumors: Mast cell tumors are the most common malignant tumors for dogs, and are usually solitary lumps found on the body or legs. Breeds which are at risk include Beagles, Boston Terriers, Boxers, Labrador Retrievers, Pugs, and Schnauzers.
