  1. 1. Heterotopic Ossification : Clinical and Experimental Studies on Risk Factors, Etiology and Inhibition by Non-steroidal Anti-inflammatory Drugs

    Författare :Per-Erik Persson; Olle Nilsson; Per Aspenberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Heterotopic ossification; Hip prosthesis; NSAIDs; Prophylaxis; Prosthesis loosening; Reoperation; Animal model; Bone formation; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : In this thesis, occurrence of heterotopic ossification (HO) following total hip arthroplasty (THA) was studied. Preventive effects and complications with non-steroidal anti-inflammatory drugs (NSAIDs) were analyzed. Experimental investigations on bone formation were employed to gain insight to the mechanism of NSAIDs action on bone.(I). LÄS MER

  3. 2. Experimental studies on fracture healing. Biological and biomechanical aspects

    Författare :Hans Mark; Göteborgs universitet; []
    Nyckelord :fracture; intramembranous; endochondral; ossification; neovascularization; fracture fixation; fracture stability;

    Sammanfattning : Considerable advances have been made in the knowledge regarding fracture healing and treatment duringrecent decades. Nevertheless, in 5-10 per cent of fractures, there are healing complications leading to complextreatment conditions, discomfort for patients and considerable costs. LÄS MER

  4. 3. Displaced Femoral Neck Fractures : A prospective randomized study of clinical outcome, nutrition and costs

    Författare :Torsten Johansson; Ola Wahlström; Karl-Göran Thorngren; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arthroplasty; replacement; hip; adverse effects; economics; fracture fixation; internal; femoral neck fractures; surgery; ossification; heterotropic; etiology; nutritional support; Orthopaedics; Ortopedi;

    Sammanfattning : Displaced femoral neck fractures comprise more than a third of all hip fractures. There is controversy as to the optimal treatment. Despite attempts to improve the methods for internal fixation, complication rates have been almost unchanged: 20-40% non-union and late segmental collapse in another 10-20%. LÄS MER

  5. 4. Functions of Heparan Sulfate During Mouse Development : Studies of Mice with Genetically Altered Heparan Sulfate Biosynthesis

    Författare :Maria Ringvall; Lena Kjellén; Erik Forsberg; Ulf Lindahl; Erika Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; embryonic development; gene targeting; lung development; ossification; heparan sulfate; heparin; N-deacetylase N-sulfaotransferase; NDST; proteoglycan; morphogen; biosynthesis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : Heparan sulfate (HS) is a ubiquitous polysaccharide on the cell surface and in the extracellular matrix. HS is an important actor in the regulation of cell signaling, especially in the developing embryo. LÄS MER

  7. 5. Development and clinical significance of side bones in cold-blooded trotters

    Författare :Ulf Hedenström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Ossification of ungular cartilages (OUC) is apparent on fossil P3 bones and seems to be as old as the history of Equus. OUC has been scientifically studied at least since the 18th century. LÄS MER
