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 cord tumors can cause weakness, paralysis, or numbness. The spinal cord is a narrow structure, so tumors within it usually cause symptoms on both sides of the body (for example, weakness or numbness of both legs). This is different from most brain tumors, which often affect only one side of the body.
