Objective: Indications for surgical treatment of hydrocephalus (HC) can vary across centers. The authors sought to investigate the frequencies of surgically treated HC disorders and to study variations in the practice of shunt surgery in Norway, a country with universal and free healthcare.
Methods: This is a nationwide registry-based study using data from the Norwegian Patient Registry.
Objective: The primary aim of this study was to evaluate the global outcome longitudinally over 5 years in children and adolescents surviving moderate to severe traumatic brain injury (msTBI) to investigate changes in outcome over time. The secondary aim was to explore how age at the time of injury affected outcome.
Methods: All children and adolescents (aged 0-17 years; subdivided into children aged 0-10 years and adolescents aged 11-17 years) with moderate (Glasgow Coma Scale [GCS] score 9-13) or severe (GCS score ≤ 8) TBI who were admitted to a level I trauma center in Norway over a 10-year period (2004-2014) were prospectively included.
Introduction: Shunt surgery in children is associated with high revision and complication rates. We investigated revision rates and postoperative complications to specify current challenges associated with pediatric shunt surgery.
Methods: All patients aged < 18 years admitted to St.
Importance: Surgical treatment for cervical radiculopathy is increasing. Treatment with motion preserving anterior cervical disc arthroplasty was introduced to prevent symptomatic adjacent segment disease, and there is need to evaluate results of this treatment compared with standard anterior cervical discectomy and fusion.
Objective: To investigate clinical outcomes at 5 years for arthroplasty vs fusion in patients who underwent surgical treatment for cervical radiculopathy.
Revision and complication rates in adult shunt surgery: a single-institution study.

Background: CSF diversion with shunt placement is frequently associated with need for later revisions as well as surgical complications. We sought to review revision and complication rates following ventriculoperitoneal, ventriculoatrial and cystoperitoneal shunt placement in adult patients, and to identify potential risk factors for revision surgery and postoperative complications.
Method: Included patients were adults (≥ 18 years) who underwent primary shunt insertion at St.
Background: An external ventricular drain (EVD) is typically indicated in the presence of hydrocephalus and increased intracranial pressure (ICP). Procedural challenges have prompted the development of different methods to improve accuracy, safety, and logistics.
Objectives: EVD placement and complications rates were compared using two surgical techniques; the standard method (using a 14-mm trephine burrhole with the EVD tunnelated through the skin) was compared to a less invasive method (EVD placed through a 2.
Objective: In this study we wanted to estimate population-based rates of incidence and mortality of moderate and severe traumatic brain injury (TBI) in children in one specific region in Norway.
Methods: In the region there are seven acute care hospitals (ACHs) in addition to a Level 1 trauma centre. Of 702 869 inhabitants (2014), 145 395 were children aged 0-16 years.
Purpose: Standard surgical treatment for symptomatic cervical disc disease has been discectomy and fusion, but the use of arthroplasty, designed to preserve motion, has increased, and most studies report clinical outcome in its favor. Few of these trials, however, blinded the patients. We, therefore, conducted the Norwegian Cervical Arthroplasty Trial, and present 2-year clinical outcome after arthroplasty or fusion.

Previous reports have mainly focused on various semiconstrained devices and only a few publications have focused on ossification around devices that are nonconstrained. The purpose of this study was to assess the occurrence of heterotopic ossification around a nonconstrained cervical device and how it affects clinical outcome 2 years after surgery.

Case Presentation: We present a rare case of post-traumatic epidural tension pneumocephalus in a 30-year-old white man who deteriorated rapidly after a blunt head trauma.
Object: It has recently been suggested that the degree of intracranial pressure (ICP) above the treatment goal can be estimated by the area under the curve (AUC) of ICP versus time in patients with severe traumatic brain injury (TBI). The objective of this study was to determine whether the calculated "ICP dose"-the ICP AUC-is related to mortality rate, outcome, and Marshall CT classification.
Methods: Of 135 patients (age range 1-82 years) with severe TBI treated during a 5-year period at the authors' institution, 113 patients underwent ICP monitoring (84%).
Objective: This study compares injury severity and outcome of patients with severe head injury admitted directly to a neurosurgical department with those initially transferred to a local hospital.
Methods: A retrospective analysis of all patients with severe head injury admitted to the Department of Neurosurgery at St Olav University Hospital, Norway, was carried out from 1998 throughout 2002.
Results: The study included 146 patients with a median age of 34 (1-88) years.
Objective: To assess long-term outcome in survivors after severe head injury and relate outcome to injury severity.
Design: Follow-up 3-8 years post injury in a retrospectively collected sample.
Setting: A neurosurgical department in a regional trauma centre.
