1. 1. Carbon reinforced UHMWPE composites for orthopaedic applications : characterization and biological response to wear particles

   Författare :Silvia Suñer Moreno; Jeffrey Dixon; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : Joint replacements have considerably improved the quality of life of patients with joints damaged by disease or trauma. However, problems associated with wear particles generated due to the relative motion between the components of the bearing are still present and can lead to the eventual failure of the implant.

3. 2. Mechanical optimization of orthopaedic bone screw constructs

   Författare :Yijun Zhou; Cecilia Persson; Benedikt Helgason; Philip Procter; Richie Gill; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; screw implant; explicit finite element modelling; computed tomography; numerical optimization; neural network; hydrogel; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

   Sammanfattning : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. LÄS MER

4. 3. Anterior Cruciate Ligament Reconstruction - Graft failures, surgical techniques and patient-reported outcome measures

   Författare :Haukur Björnsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; knee; anterior cruciate ligament; double-bundle; single-bundle; register; hamstring tendon; patellar tendon; graft failure; patient-reported outcome measures;

   Sammanfattning : Injuries to the anterior cruciate ligament (ACL) can result in increased joint laxity, which often ends participation in competitive sports and may, in the medium to long term, lead to degeneration of the knee. The occurrence of ACL injuries has increased in recent years and, today, ACL reconstruction is one of the most common procedures in orthopaedic surgery. LÄS MER

5. 4. Aspects of bone quality and risk assessments in fracture and elective orthopaedic patients

   Författare :Camilla Bergh; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fracture; Fracture incidence; Epidemiology; Mortality; Osteoporosis; Frailty; Spinal stenosis; Bone quality; Bone mineral density;

   Sammanfattning : Background: Bone quality, bone strength, and bone remodelling are important in many orthopaedic conditions and can have an impact on fracture incidence, bone healing, implant failure, and different outcome aspects. There is relatively sparse information on fracture incidence and mortality both for all fractures compiled and for some of the individual fracture locations. LÄS MER

7. 5. Renal dysfunction in orthopaedic surgery - with special reference to drug effects in the elderly

   Författare :Görel Nergelius; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; protein HC; IgG; albumin; pharmacokinetics; diclofenac; clearance; elderly; penicillin; isoxazolyl; tubular; glomerular; arthroplasty; exercise; traumatology; Kirurgi; ortopedi; traumatologi; Anaesthesiology; intensive care; Anestesiologi; intensivvård;

   Sammanfattning : Total hip replacement (THR) is a common procedure, generally performed in elderly persons. Previous studies indicated that the use of isoxazolyl penicillins could induce a transient post-operative renal dysfunction in these patients. LÄS MER
