Outpatient surgery is becoming more common and is more cost-effective than inpatient surgery. Nonetheless, many surgeons and health care administrators are still hesitant to accept outpatient surgery for cervical degenerative spinal disease (C-DSD). This study assesses the types and rates of complications, hospital admissions, and reoperations after outpatient surgery of C-DSD.

Background: To date, the traditional approach to intraspinal tumors has been open laminectomy or laminoplasty followed by microsurgical tumor resection. Recently, however, minimally invasive approaches have been attempted by some.

Objective: To investigate the feasibility and safety of minimally invasive surgery (MIS) for primary intradural spinal tumors.

Background: Patient selection for surgical treatment of subaxial cervical spine fractures (S-CS-fx) may be challenging and is dependent on fracture morphology, the integrity of the discoligamentous complex, neurological status, comorbidity, risks of surgery and the expected long-term outcomes. The purpose of this study is to evaluate complications and long-term outcomes in a consecutive series of 303 patients with S-CS-fx treated with open surgical fixation.

Methods: Medical charts were retrospectively reviewed.

Background: The incidence rate of surgical treatment of cervical degenerative diseases (CDD) has increased in the USA and a large geographic variation has been shown. Little is known about such rates in Scandinavia and Europe. The aim of this population-based study was to (1) investigate annual incidence rates of operations performed in Norway, (2) to compare trends and variations in rates for surgical indications with and without myelopathy, and (3) to compare variations in the use of surgery between residential areas.

Background: The existing literature on recurrence rates and long-term clinical outcome after resection of intraspinal nerve sheath tumors is limited.

Objective: To evaluate progression-free survival, overall survival, and long-term clinical outcome in a consecutive series of 131 patients with symptomatic intraspinal nerve sheath tumors.

Methods: Medical charts were retrospectively reviewed.

Background: There is an increasing demand for surgery of degenerative spinal disease. Limited healthcare resources draw attention to the need for cost-effective treatments. Outpatient surgery, when safe and feasible, is more cost effective than inpatient surgery.

Background: The incidence of cervical spine fractures (CS-fx) in the general population is sparingly assessed. The aim of the current study was to estimate the incidence of traumatic CS-fx and of open surgery of cervical spine injuries in the Norwegian population.

Methods: The Norwegian Patient Register (NPR) is an administrative database that contains activity data from all Norwegian government-owned hospitals and outpatient clinics.

Aim: The aim of this study was to estimate the incidence of traumatic cervical spine fractures (CS-fx) in a general population.

Background: The incidence of CS-fx in the general population is largely unknown.

Methods: All CS-fx (C0/C1 to C7/Th1) patients diagnosed with cervical-CT in Southeast Norway (2.

Background: The purpose of this study was to determine the incidence of surgery for odontoid fractures and to study surgical mortality, surgical morbidity, and long-term outcome in a large, contemporary, consecutive, single-institution, surgical series of odontoid fractures.

Methods: This is a retrospective study of all odontoid fractures treated by open surgery at our hospital during 2002 to 2009. The fractures were classified according to Grauer.

Study Design: This is a retrospective review of prospectively collected data.

Background: Primary, intradural spinal tumours have traditionally been microsurgically resected following macrosurgical laminectomy or laminoplasty. We hypothesize that approach-related morbidity can be reduced with less-invasive approaches; we have therefore implemented a minimally invasive approach, with the assistance of a tubular retraction system, for microsurgical resection of primary intradural spinal tumours.

Objective: To evaluate progression-free survival, overall survival (OS) and long-term clinical outcome in a consecutive series of 86 patients with intraspinal ependymomas.

Methods: Medical charts were retrospectively reviewed. Surviving patients voluntarily participated in a clinical history and physical examination that focused on neurological function and current tumor status.

Background: Anterior cervical discectomy with fusion (ACDF) is challenging with respect to both patient selection and choice of surgical procedure. The aim of this study was to evaluate the clinical outcome of ACDF, with respect to both patient selection and choice of surgical procedure: fusion with an autologous iliac crest graft (AICG) versus fusion with an artificial cage made of polyetheretherketone (PEEK).

Methods: This was a non-randomized prospective single-center outcome study of 258 patients who underwent ACDF for cervical disc degeneration (CDD).

Throughout many years, a large number of publications have focused on structural changes in soft tissues in the cervical spine in patients with whiplash associated disorders I-II. In recent years the development in MRI techniques have made it possible to visualize the small ligaments in the craniocervical junction; a small number of publications have investigated the association between signal changes in these ligaments and whiplash associated disorders I-II. The results are, however, not conclusive, and no prospective studies have demonstrated any causal connection between type of whiplash injury and signal changes in these ligaments.
