2. 1. Survival of onlay bone grafts. A study in the adult rat

   Author : Monica Gordh; Lunds universitet; []
   Keywords : 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;

   Abstract : 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. 2. Revision Hip Arthroplasty : Impaction Bone Grafting and Low-Dose CT-Based Measurements of Bone Density and Migration

   Author : Hampus Stigbrand; Gösta Ullmark; Nils Hailer; Per Wretenberg; Uppsala universitet; []
   Keywords : Revision Hip Arthroplasty; Bone Grafting; Computed Tomography; Bone Mineral Density; CTMA; Orthopaedics; Ortopedi;

   Abstract : Aseptic loosening of total hip replacements is always associated with bone defects, either due to removal of the existing implant or osteolysis. Bone defects can be handled during revision surgery with impaction bone grafting (IBG). READ MORE

5. 3. Aspects of maxillary sinus reconstruction with endosseous implants

   Author : John Eric Blomqvist; Lunds universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Odontologi; Odontology; stomatology; sinus inlay bone augmentation.; osteomorphometry; osteometry; maxillary sinus reconstruction; maxilla; bone graft; Alveolar bone loss; dental implants; implant position; bone;

   Abstract : This study of maxillary sinus reconstruction in conjunction with insertion of endosseous implants included 99 patients. Two separate surgical methods were applied; a one-staged strategy (n=49) and a two-staged strategy (n=50). The aims were to compare two different strategies concerning implant and prosthetic construction survival. READ MORE

6. 4. Bone Regeneration with Cell-free Injectable Scaffolds

   Author : Gry Hulsart Billström; Sune Larsson; Kenneth B Jonsson; Jöns Hilborn; Håkan Engqvist; Olle Svensson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone tissue engineering; hydrogel; computed tomography; positron emission tomography; large femoral bone defect; rat model; hydrogel; in vivo; osteogenesis; bone regeneration; 3R; single-photon emission computed tomography; bone morphogenetic protein 2; calcium phosphates; injectable; bisphosphonate;

   Abstract : Bone is a remarkable multifunctional tissue with the ability to regenerate and remodel without generating any scar tissue. However, bone loss due to injury or diseases can be a great challenge and affect the patient significantly. Autologous bone grafting is commonly used throughout the world. READ MORE

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

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

   Abstract : 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. READ MORE
