  1. 16. Idiopathic scoliosis : aspects on surgical and non-surgical treatment

    Författare :Anastasios Charalampidis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The term scoliosis has been used to describe conditions that lead to deformation of the spine. It derives from the ancient Greek ‘σκολίωσις’ and the root word ‘σκολιός’ which means ‘bent or crooked’. In its most common form, scoliosis is of unknown - idiopathic - cause and origin. LÄS MER

  3. 17. Early onset spine deformity : outcome of surgical treatment and 3D movement analysis of sitting

    Författare :Girts Murans; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Early onset, non-idiopathic spine deformities are progressive and associated with increased respiratory and cardiovascular morbidity and mortality as well as neurological and functional deteriorations. If untreated, the deformity progression can continue throughout the adult life and conclude with early mortality mostly due to cardio-pulmonary reason. LÄS MER

  4. 18. Whiplash injury : a clinical, radiographic and psychological investigation

    Författare :Kurt Pettersson; Seppo Santavirta; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cervical spine; whiplash injury; MRI; personality traits; steroid therapy; sagittal canal diameter; chronic symptoms;

    Sammanfattning : Whiplash injury is a common and troublesome disorder and approximately 10-40 per cent of its victims develop chronic symptoms. The annual incidence is estimated at 1/1000 inhabitants and the prevalence at 1%. The cause of chronic symptoms after whiplash injury is still unknown and no effective treatment has been presented so far. LÄS MER

  5. 19. Robust Image Registration for Improved Clinical Efficiency : Using Local Structure Analysis and Model-Based Processing

    Författare :Daniel Forsberg; Hans Knutsson; Mats Andersson; Claes Lundström; Wiro Niessen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image registration; deformable models; scoliosis; visualization; volume rendering; adaptive regularization; GPGPU; CUDA;

    Sammanfattning : Medical imaging plays an increasingly important role in modern healthcare. In medical imaging, it is often relevant to relate different images to each other, something which can prove challenging, since there rarely exists a pre-defined mapping between the pixels in different images.

  7. 20. Spark plasma sintered ZrO2-SiO2 glass ceramics and Si3N4 bioceramics

    Författare :Le Fu; Wei Xia; Håkan Engqvist; Jérôme Chevalier; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZrO2-SiO2 glass ceramic; high-strength; translucency; 3D nano-architecture; Si3N4 bioceramic; biodegradable; spark plasma sintering; Materialvetenskap; Materials Science;

    Sammanfattning : This thesis focuses on elaboration and characterization of two types of bioceramics: one is ZrO2-SiO2 nanocrystalline glass ceramic (NCGC) for dental application. The goal is to develop new ZrO2-SiO2 NCGCs with a combination of high strength and high translucency; the other is biodegradable Si3N4 ceramics for spinal fusion. LÄS MER
