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 tumors may be either benign (not cancer) or malignant (cancer): Benign brain and spinal cord tumors grow and press on nearby areas of the brain. They rarely spread into other tissues and may recur (come back). Malignant brain and spinal cord tumors are likely to grow quickly and spread into other brain tissue.
