161 Schmidt, Meic H.Is vertebral augmentation the right choice for cancer patients with painful vertebral compression fractures?Cancer-related fractures of the spine are different from osteoporotic ones, not only in pathogenesis but also in natural history and treatment.

162 Schmidt, Meic H.Isolated intramedullary neurosarcoidosis of the thoracic spine: case report and review of the literatureSarcoidosis can involve the central nervous system in approximately 5-15% of cases. Any part of the nervous system can be involved, so presentation can be quite varied. Isolated disease of the spinal cord is even less common and reports are limited to single cases and small series. Although in the s...2012-01-01
