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.
A primary brain or spinal cord tumor is a tumor that starts in the brain or spinal cord. This year, an estimated 23,800 adults (13,450 men and 10,350 women) in the United States will be diagnosed with primary cancerous tumors of the brain and spinal cord this year.
