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 compression by degenerative spine disease is one of the more common causes of myelopathy, however tumors or other masses can also cause myleopathies. Intraspinal tumors may originate in the substance of the spinal cord (intramedullary tumors) or compress it from the outside (extramedullary tumors).
