1. 26. Wear and Loosening in Cemented Hip Arthroplasty

   Författare :Uldis Kesteris; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ortopedi; Kirurgi; traumatology; orthopaedics; Surgery; traumatologi;

   Sammanfattning : The mechanisms of loosening in total hip arthroplasty (THA) and the role of polyethylene (PE) wear debris in this process is unclear. Radiographic measurements showed that THA with 32 mm heads have about 3 times greater volumetric wear than those with 22 mm heads. LÄS MER

3. 27. Clavicle Fractures : Epidemiology, classification, treatment and outcome, with emphasis on displaced lateral clavicle fractures

   Författare :Caroline Kihlström; Olof Wolf; Hanna Björnsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clavicle fractures; Displaced lateral clavicle fractures; Epidemiology; Classification; Treatment; Outcome; The Swedish Fracture Register; Validation; Orthopaedics; Ortopedi;

   Sammanfattning : The rate of surgical treatment for clavicle fractures has increased dramatically in the past 20 years, but the necessity for this remains obscure, particularly for displaced lateral clavicle fractures. The overall aim of the thesis is to acquire knowledge that may help guide treatment decisions for clavicle fractures, with an emphasis on displaced lateral fractures. LÄS MER

4. 28. Bone Enhancement with BMP-2 for Safe Clinical Translation

   Författare :Marta Kisiel; Jöns Hilborn; Monica Wiig; Richard Oreffo; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone repair; Bone healing; Bone morhogenetic protein-2; Osteogenesis; Extracelular matrix; Hyaluronan; Animal model; Orthopaedics; Ortopedi; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot materialvetenskap;

   Sammanfattning : Bone morphogenetic protein-2 (BMP-2) is considered a promising adjuvant for the treatment of bone regeneration. However, BMP-2 delivery in a conventional collagen scaffold needs a high dose to achieve an effective outcome. Moreover, such dosage may lead to serious side effects. LÄS MER

5. 29. Non-ionic contrast media in acrylic bone cement

   Författare :Fred Kjellson; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; Material technology; Materiallära; materialteknik; PMMA; Bone cement; particle size; contrast media; radiopacity; iohexol; iodixanol; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; orthopaedics; Surgery; medicinsk instrumentering;

   Sammanfattning : Non-ionic, water-soluble, contrast media, iohexol and/or iodixanol, have been investigated for use in acrylic bone cement aimed for arthroplasty. Bone cement, containing the new particulate contrast media , was investigated for: quasi-static mechanical properties, water uptake properties, release of contrast media from the bone cement, biological responses from particulate bone cement, polymerisation reaction, polymerisation temperature, glass transition temperature, injectability and penetration into human cancellous bone, and radiopacity.

7. 30. Lumbar spinal stenosis : Body mass index and the patient's perspective

   Författare :Björn Knutsson; Karl Michaëlsson; Bengt Sandén; Göran Sjödén; Paul Gerdhem; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antonovsky; back pain; BMI; body mass index; Bygghalsan; cohort study; coping; EQ-5D; excess weight; leg pain; LSS; lumbar spinal stenosis; obesity; ODI Oswestry disability index; overweight; patient-centered; patient-physician relationship; patient-perspective; patient-related-outcome-measure; PROMs; qualitative study; spinal stenosis; salutogenesis; salutogenic; sciatica; spine surgery; suffering; Swedish spine register; Swespine; VAS; weight loss; weight change; Orthopaedics; Ortopedi;

   Sammanfattning : During recent decades, lumbar spinal stenosis (LSS) has become the most common indication for spine surgery, a change that coincides with a higher worldwide prevalence of overweight and obesity. Thus, surgical treatment of LSS in the overweight and obese population is common and increasing in scope. LÄS MER
