1. Implant Movement Analysis in theroutine diagnosis of aseptic looseningafter hip arthroplasty, a two year followup
Kandidat-uppsats, Örebro universitet/Institutionen för medicinska vetenskaperSammanfattning : Introduction: A major long-term complication after hip arthroplasty is aseptic loosening.Conventional planar radiographs cannot always provide a certain diagnosis, which makesdecisions regarding revision surgery difficult.

2. Evaluation of the role of ImplantMovement Analysis in diagnosing asepticloosening of total hip arthroplasty
Master-uppsats, Örebro universitet/Institutionen för medicinska vetenskaperSammanfattning : Introduction: Aseptic loosening is the most common indication for revision surgery of hipimplants. However, sometimes diagnosis from planar radiography is uncertain, makingdecision regarding revision surgery problematic. Implant Movement Analysis (IMA) is anewly introduced method of analysing uncertain aseptic loosening of hip prostheses. LÄS MER
3. Radiostereometry Using NURBS Implant Models
Master-uppsats, Umeå universitet/Institutionen för datavetenskapSammanfattning : Radiostereometric analysis (RSA) is a method used for determining migration and wear of orthopaedic implants through measurements performed in radiographs. There are two approaches of RSA: marker-based and model-based (MBRSA). Marker-based RSA is the conventional and most accurate method. LÄS MER
4. Model test for fabrication and separation of wear particles in hip implants
Uppsats för yrkesexamina på avancerad nivå, Tillämpad materialvetenskapSammanfattning : Total hip replacement is a common orthopedic surgery today with a population with an increasing life expectancy and a more active lifestyle. Most implants have a life expectancy of 10 years or longer, however after 25 years one out of four implants has been revised. This means that the risk of a secondary surgery is high for young patients. LÄS MER
5. Optimizing and method development for clinical MR imaging near metallic implants
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Metallic hip prosthesis is an implant that gets more common and comes with problems like metallosis (inflammation due to metallic debris). Magnetic resonance imaging (MRI) which is a superior method when imaging soft tissue (compared to other medical imaging techniques) is affected by metal implants and will result in a distorted image.
