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.
Fewer than 10 percent of spine tumors begin in the spine. The ones that do are called primary tumors. They can be benign (noncancerous), low-grade malignant (cancerous) tumors that grow slowly, or high-grade tumors that grow aggressively. Most spine tumors are metastatic â they spread from cancer in a different part of the body. Some spine tumors, such as astrocytomas, happen more commonly in children and teenagers. Spine Tumor Symptoms. As a spine tumor grows, it can replace your bones or compress your nerves, resulting in compression fractures or reduced blood supply to the spinal cord. Often, the first symptom of a spine tumor is the pain you feel from these changes.
