1. Wear characteristics of materials for artificial hip joints
Sammanfattning : Total hip prostheses have succeeded in significantly improving the quality of life of millions of patients worldwide. Ultra high molecular weight polyethylene (UHMWPE) has been widely and successfully used as a bearing material in orthopaedic prostheses since the 1960s. LÄS MER
2. The Uncemented Cup in Total Hip Arthroplasty : stability, Wear and Osteolysis
Sammanfattning : Background: Artificial hip joint replacement has undergone tremendous development in the past 100 years. In the beginning, complications, such as infection and early loosening, were the rule rather than the exception. Today, complications of any sort are rare during the first decade after the operation.

3. Time dependent flow of biolubricant and suspended particles behavior within total hip replacement
Sammanfattning : Total hip replacement (THR) has been one of the most successful surgeries in the 21st century. Ultra-high-molecular-weight-polyethylene (UHMWPE) shows favorable mechanical and tribological properties when used as a bearing surface material in THR. However, produced UHMWPE wear particles challenge increasing the THR lifetimes. LÄS MER
4. A clinical study of uncemented hip arthroplasty : radiological findings of host-bone reaction to the stem
Sammanfattning : In total hip arthroplasty (THA), the main reason for failure leading to revision is aseptic loosening. Both mechanical and biological effects act in the loosening process, the factors may be implant design, fixation mode or technique, as well as biological factors unique to the individual. LÄS MER
5. Investigation of Carbon Reinforced UHMWPE Nanocomposites for use in Orthopaedics
Sammanfattning : Over the lifetime of a person, the function of the natural hip joint can be altered due to trauma or disease and an artificial hip replacement may eventually be required. Ultra high molecular weight polyethylene (UHMWPE) is considered the gold standard material for the acetabular cup in hip arthroplasties. LÄS MER
