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.
Spinal tumors may be primary which start in the spinal cord or secondary which result from metastasis (transmission of cancerous cells) from other cancers in the body. Primary spinal tumors are sometimes benign, but more commonly they are malignant.pinal malignancies are most often secondary tumors resulting from metastasis. Spinal cancer can occur in the form of lymphoma and accounts for 1% of the central nervous system lymphomas. The incidence of spinal cancer increases with age and can occur in both males and females.
