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.
The spine is the third most common site for cancer cells to metastasis, following the lung and the liver. Approximately 5-30% of patients with systemic cancer will have spinal metastasis; some studies have estimated over 30-70% of patients with a primary tumor have spinal metastatic disease at autopsy.Spinal metastases are slightly more common in men than in women and in adults aged 40-65 years than in others.ntradural extramedullary and intramedullary seeding of systemic cancer is unusual; they account for 5-6% and 0.5-1% of spinal metastases, respectively. Metastatic disease to the neuraxis other than the brain parenchyma and the spinal column is uncommon.
