The functionalization and cross-linking of polyethylene is synthetically challenging, commonly relying on highly optimized radical based postpolymerization strategies. To address these difficulties, a norbornene monomer containing Meldrum's acid is shown to be effectively copolymerized with polyethylene using a nickel α-iminocarbaxamidato complex, providing high-melting, semicrystalline polymer...
A 39-year-old woman underwent bilateral total hip arthroplasty with conventional, ethylene oxide-sterilised liners when she was a subject in a radiostereometric analysis study. Within 2 years she had rapid polyethylene wear with aggressive, asymptomatic, and periprosthetic osteolysis on both sides. Oral alendronate therapy halted the progression of osteolysis over a year and revision to cross-l...
Retrieval studies of total hip replacements with highly cross-linked ultra-high-molecular-weight polyethylene liners have shown much less surface damage than with conventional ultra-high-molecular-weight polyethylene liners. A recent revision hip replacement for recurrent dislocation undertaken after only five months revealed a highly cross-linked polyethylene liner with a large area of visible...
