2. 1. Legg-Calvé-Perthes´ disease. Synovitis, cartilage, remodeling

   Author : Göran Eckerwall; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stromelysin; Sonography; Remodeling; Proteoglycan; Pressure; Osteotomy; MRI; MR imaging; Metaphysis; Legg-Calvé-Perthes; Histology; Hip; Arthrography; Child; Synovitis; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Abstract : This thesis evaluates and correlates the findings in a series of children with Legg-Calvé-Perthes´ Disease at the Departments of Orthopedics, University Hospitals in Lund, Sweden and Odense, Denmark during 1984-1993. It focuses on the importance of synovitis and its effect on the cartilage, on the shape of the femoral head in the early phases of LCPD and on femoral head remodeling after proximal femoral varus derotation osteotomy.

4. 2. Magnetic Resonance Imaging in Legg-Calvé-Perthes Disease

   Author : Peter Hochbergs; Lund Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; Histology; Metaphysis; Synovitis; Necrosis; Osteotomy; Arthrography; Magnetic Resonance Imaging; Legg-Calvé-Perthes Disease; Pediatrics; Hip; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology;

   Abstract : The aims of this study were: to compare the cartilaginous outline of the femoral head obtained on arthrograms with those on MR images and to correlate it to the bony head outlines on conventional radiograps; to study early, postoperative cartilaginous and bony remodeling of the femoral head, after proximal femoral varus derotation extension osteotomy, with MR imaging and conventional radiography; to describe signal abnormalities on MR images in the femoral epiphysis, their location, extent and restitution over time; to evaluate the degree and persistence of synovitis in the hip joint by MR imaging; to analyze the metaphyseal histology and to correlate it to the signal intensity on the MR images in the corresponding biopsy region. Results and conclusions: MR imaging and arthrography define the shape of the femoral head cartilage equally well. READ MORE

5. 3. Improved titanium and steel implants : Studies on bisphosphonate, strontium and surface treatments

   Author : Paula Linderbäck; Pentti Tengvall; Per Aspenberg; Håkan Engqvist; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : Purpose: The general aim of this thesis was to increase the understanding of biomaterial surface modifications and local delivery of osteoporosis drugs for bone integration. We therefore (i) characterised and investigated model surface coatings for controlled drug delivery in a rat tibia screw model (ii) elucidated the effect of surface treatment for activation of complement system in vitro.

6. 4. Long bone growth and evolution revealed by three-dimensional imaging

   Author : Jordi Estefa; Sophie Sanchez; Per Ahlberg; Holly Woodward; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D histology; hematopoiesis; humerus; tetrapods; Biologi; Biology;

   Abstract : Propagation phase-contrast synchrotron radiation microtomography is a non-destructive method used for studying histology in three dimensions (3D). Using it, the 3D organization of the diaphyseal cortical vascularization in the humerus of two seymouriamorphs was analyzed in this thesis. READ MORE

7. 5. Functional aspects of prothrombin in bone

   Author : Erik Karlström; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Prothrombin (PT) is the inactive zymogen to the serine protease alpha-thrombin which in the coagulation cascade is responsible for clot formation through converting fibrinogen to fibrin. PT has been shown to be present in calcified bone matrix, and alpha-thrombin has been implicated in various bone resorbing disorders of inflammatory origin, such as rheumatoid arthritis and periodontitis.
