  1. 1. 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

  3. 2. Matrix resorption in endochondral bone growth : ultrastructural studies, with special attention to the chondroclast

    Författare :Joakim Nordahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :chondroclast; osteoclast; cartilage resorption; TRAP; cathepsin K; fibronectin; bone sialoprotein; osteopontin;

    Sammanfattning : A substantial amount of the calcified cartilage in the distal parts of the epiphyseal plate is resorbed during endochondral growth of long bones. However, the mechanisms involved in this process are still largely unknown. On the other hand, bone-resorption in the lower metaphysis has been thoroughly investigated. LÄS MER

  4. 3. Insulin-like growth factor-I from a perspective of bone regeneration

    Författare :Per Prisell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :insulin-like growth factor-I; fracture healing; endochondral bone formation; slow release; indomethacin; corticosteroids; hyaluronan; von Kossa;

    Sammanfattning : The insulin-like growth factor I (IGF-I) is produced by osteoblasts and many other cell types. IGF-I is abundant in bone matrix and mediates some of the effects of growth hormone (GH). The present investigations have focused on IGF-I actions during bone regeneration. LÄS MER

  5. 4. The distribution and concentration of zinc and the effects of zinc deficiency in the mammalian body : some experiments in mice and rats with special reference to mandibular condyle and some other skeletal tissues

    Författare :Bo Bergman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This thesis constitutes a summary of the following series of studies:I Autoradiographic studies on the distribution of zinc-65 in mice. In collaboration with Rune Söremark. The Journal of Nutrition 94,6, 1968. LÄS MER

  7. 5. Modelling loading and growth of long bones Modelling loading and growth of long bones

    Författare :Priti Yadav; Elena Gutierrez-Farewik; Anders Eriksson; Eva Pontén; Hanna Isaksson; KTH; []
    Nyckelord :Growth Plate; Finite element analysis; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : The long bones grow by the process of endochondral ossification, which occurs at the growth plate. This process is regulated by biological factors and mechanical factors. The biological factors which contribute to endochondral ossification process are genes, hormones, nutrients etc. The mechanical factor is the load acting on the bone. LÄS MER
