Risk factors for low back pain and sciatica in elderly men-the MrOS Sweden study.

Introduction: The aim of this study was to identify whether factors beyond anatomical abnormalities are associated with low back pain (LBP) and LBP with sciatica (SCI) in older men.

Material And Methods: Mister Osteoporosis Sweden includes 3,014 men aged 69–81 years. They answered questionnaires on lifestyle and whether they had experienced LBP and SCI during the preceding 12 months.

Characteristics of Prevalent Vertebral Fractures Predict New Fractures in Elderly Men.

Background: Studies have shown that specific characteristics of prevalent vertebral fractures are associated with a markedly low bone mineral density. This study evaluates if these characteristics also predict subsequent fractures.

Methods: MrOS (Mister Osteoporosis) Sweden is a population-based, prospective observational study that includes 3014 community-living men who are sixty-nine to eighty-one years of age.

Low clinical relevance of a prevalent vertebral fracture in elderly men--the MrOs Sweden study.

Background Context: The epidemiology, the fracture pattern, and the clinical relevance of prevalent vertebral fractures in old men are debated wherefore we set out to clarify these issues.

Methods: Mister Osteoporosis (MrOs) Sweden is a population-based cohort of community-living men aged 69-81 years that includes 3,014 men. Out of these, 1,453 men underwent a lateral radiograph of the thoracic and lumbar spine of which 1,427 were readable and classified by a radiologist, that is the sample size in this study.

Optimization of radiation exposure and image quality of the cone-beam O-arm intraoperative imaging system in spinal surgery.

Study Design: Retrospective study.

Objectives: To optimize the radiation doses and image quality for the cone-beam O-arm surgical imaging system in spinal surgery.

Summary Of Background: Neurovascular compromise has been reported after screw misplacement during thoracic pedicle screw insertion.
