Objective: Chronic subdural hematomas (cSDH) represent a common neurosurgical pathology with an incidence of 1.7-20.6 per 100,000 persons per year. Surgical evacuation shows a significant recurrence rate with the need of reevacuation in up to 10-20%. Endovascular middle meningeal artery embolization[for full text, please go to the a.m. URL], 72.

Objective: Primary bone tumours (PBTs) of the spine are considered to be a rare disease. They represent less than 0.2% of all newly diagnosed tumours. The aim of this study was to report a large contemporary single-center series of PBTs of the spine and review the concepts of management. Methods:[for full text, please go to the a.m. URL], 71.

Objective: We aimed to optimize the postoperative pain management following spine surgery. Methods: A quasi-experimental study was performed from January till June 2018. Patients were postoperatively classified into three numeric rated scale (NRS) score groups: slight (NRS 0-4), moderate (NRS [for full text, please go to the a.m. URL], 70.

Objective: Median survival after diagnosis of glioblastoma remains 15 months among all patients with aggressive surgical resection, chemotherapy, and radiation. Treatment of patients with poor preoperative Karnofsky performance status (KPS) is still controversial. We therefore assessed retrospectively[for full text, please go to the a.m. URL], 69.

Objective: Glioblastoma (GB) is the most common and aggressive primary brain tumor in adults. Almost all tumors show early recurrence and fatal outcome, despite aggressive therapy regimes. Several prognostic factors have been established, including age, Karnofsky Performance Score (KPS), extent of resection,[for full text, please go to the a.m. URL], 69.

Objective: Ischemic complications during aneurysm surgery are a frequent cause of postoperative neurological deficits. Motor-evoked potentials (MEPs) are used in order to minimize the risk of such deficits.

Objective: Postoperative ischemia is a frequent phenomenon in patients with brain tumors and is also responsible for many cases of postoperative neurological deficits. Particularly in the field of cardiac surgery, but also in other fields, it has been shown that the application of a brief ischemic stimulus[for full text, please go to the a.m. URL], 68.

Objective: Unstable osteoporotic fractures require often 360 degrees Fusion with posterior pedicle Fixation and a vertebral body replacement with a distractible cage. We analyzed the thoracolumbar geometry before and after both procedures. Methods: Twenty-six consecutive patients (20 female, 6 male)[for full text, please go to the a.m. URL], 68.

Objective: Cognitive deficits are widely described in patients with aneurysmal subarachnoid haemorrhage. However, only few series report on neuropsychological outcome after elective treatment of unruptured aneurysms. In this context, several authors have suggested that surgical clipping may lead to [for full text, please go to the a.m. URL], 66. Jahrestagung der Deutschen Gesellschaft für Neurochirurgie (DGNC)

Objective: GBM is almost always recurring despite aggressive therapy. Complete removal of contrast enhancing tumor mass is a strong prognostic factor but adjuvant therapies such as radiochemotherapy are a decisive part of the treatment strategy to prolong the time to recurrence.
