  7. 20. The acute osteoporotic vertebral compression fracture. Its natural course and characteristics

    Author : Nobuyuki Suzuki; Göteborgs universitet; []
    Keywords : Vertebral body fracture; Osteoporosis; Pain; Quality of life; Disability; Compression fracture; Prognosis; Treatment; Prevalent fracture; Epidemiology;

    Abstract : Aim: The overall aim of this thesis was to investigate the natural course and the characteristics of the acute osteoporotic vertebral compression fracture in order to better understand and improve treatment for this type of fracture. Patients and methods: Eligible patients were all patients over 40 years of age who sought medical care at the emergency unit at Sahlgrenska University Hospital (studies I-III) or referred to the X-ray Department at Capio Diagnostic Center (study IV) because of back pain with a radiographically-confirmed acute vertebral body fracture which resulted from a low energy trauma.
