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.
These numbers are for some of the more common types of brain and spinal cord tumors. Numbers are not readily available for all types of tumors, often because they are rare or are hard to classify. Type of Tumor. 5-Year Relative Survival Rate. Age. 20-44. 45-54. 55-64.
