STUDY DESIGN: Retrospective administrative database study. OBJECTIVE: To assess temporal and regional trends, and length of hospital stay, in lumbar spinal stenosis (LSS) surgery in Norwegian public hospitals from 1999 to 2013. SUMMARY OF BACKGROUND DATA: Studies from several countries have reported increasing rates of LSS surgery over the last decades. No such data have been presented from Norway. METHODS: A database consisting of discharges from all Norwegian public hospitals was established...

STUDY DESIGN: Multi-center, retrospective cohort study. OBJECTIVE: To determine the epidemiology, identify predictors of early mortality, and develop predictive models for traumatic spinal cord injury (SCI). SUMMARY OF BACKGROUND DATA: Despite improved initial care and management strategies, traumatic SCI remains a devastating event. Knowledge of the epidemiological state and predictive factors for mortality is important for developing strategies and counseling; however, they have not been adequately investigated, and predictive modeling regarding outcomes remains an underused modality for patients with traumatic SCI...

STUDY DESIGN: An Internet-based assessment of websites using recognized score systems. OBJECTIVE: To assess the quality, content, and readability of online information for failed back spinal surgery (FBSS). SUMMARY OF BACKGROUND DATA: A significant amount of patients still suffer from chronic or recurrent back pain with or without radicular symptoms after spinal surgery. More and more patients use the Internet to find health-related information...

STUDY DESIGN: In vitro experimental study. OBJECTIVES: To investigate the impact of increased osteoblastic activity on the proliferation and survival of MM plasma cells in vitro SUMMARY OF BACKGROUND DATA.: Multiple myeloma (MM) is one of representative hematologic malignancies that cause skeletal-related events (SREs) and dysregulation of bone remodeling is known as a key pathomechanism of disease progression and skeletal-related events. However, decreased proliferation of MM at fracture sites is frequently noted in clinical situations regardless of systemic disease activity METHODS...
