1. 6. Pharmacological manipulation of fracture healing and bone remodeling

   Författare :Anna Kajsa Harding; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pin-fixation; fracture healing; bone remodeling; bone graft; Bisphosphonate; BMP;

   Sammanfattning : Drug treatment has been and will continue to be a successful method in modern medicine that can change the course of a disease. However, it is surprisingly seldom used in the more technically oriented orthopedic surgery. LÄS MER

3. 7. Survival of onlay bone grafts. A study in the adult rat

   Författare :Monica Gordh; Lunds universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

   Sammanfattning : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

4. 8. On the semitendinosus tendon in anterior cruciate ligament reconstructive surgery

   Författare :Karl O Eriksson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Semitendinosus; anterior cruciate ligament; tendon regeneration; MRI; muscle morphology; muscle biopsy; tendon-to-bone healing; donor site morbidity; functional outcome;

   Sammanfattning : The aim of this thesis was to address issues concerning the use of the semitendinosus tendon as an autologous transplant in anterior cruciate ligament reconstructive surgery. The specific objectives of the study concern the regenerative capability of the semitendinosus tendon following its harvest, the morphology and function of the semitendinosus muscle following harvesting of its tendon, the potential for ingrowth of the semitendinosus tendon graft into the bone tunnels, the early postoperative morbidity after anterior cruciate ligament reconstruction with a quadruple sernitendinosus graft as compared to the commonly used bone-patellar tendon-bone graft and, finally, the outcome at a minimum 2-year follow-up on comparing the sernitendinosus tendon graft with the bone-patellar tendon-bone graft.

5. 9. Allograft bone in hip revision: the effect of locally applied pharmacological treatment

   Författare :Ola Belfrage; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allograft bone; bone transplantation; bisphosphonate; bone morphogenetic proteins; hip revision; radiostereometric analysis;

   Sammanfattning : The clinical success of primary hip replacement is paramount but the need for revisions will continue to increase due to the increasing number of operated individuals. In Sweden, the number of hip revisions in 2012 exceeded 2,300. During implant loosening, some of the bone in the femur is lost, which can make the revision more difficult. LÄS MER

7. 10. On tissue reactions to dentin as a bone substitute material

   Författare :Payam Farzad; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grafted dentin; tissue reaction; bone blocks; dental implants; experimental study;

   Sammanfattning : Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ability equivalent to autogenous bone but without the limitations of allogenic, xenogenic and synthetic bone are constantly ongoing.
