In Vivo Wear and Migration of High Cross Linked Poly Cups: a Rsa Study
ثبت نشده
چکیده
Aseptic loosening attributed to wear debris mediated osteolyses is the major concern in hip arthroplasty. Modern highly cross linked polyethylene reduces wear by > 90% in vitro, seemingly without major disadvantages. It has however not yet been subjected to extensive in clinical testing with high accuracy methods. Since the in vivo wear situation is complex and lab results earlier have made incorrect predictions a clinical study is needed to confirm lab data. This RSA was done to compare highly cross linked all poly cups to standard poly with respect to wear and migration profile.

Wear and migration of highly cross-linked and conventional cemented polyethylene cups with cobalt chrome or Oxinium femoral heads: a randomized radiostereometric study of 150 patients.
This randomized study was performed to compare wear and migration of five different cemented total hip joint articulations in 150 patients. The patients received either a Charnley femoral stem with a 22.2 mm head or a Spectron EF femoral stem with a 28 mm head. The Charnley articulated with a γ-sterilized Charnley Ogee acetabular cup. The Spectron EF was used with either EtO-sterilized non-cros...
متن کاملValidation of a new 2-D technique for radiographic wear measurement of cemented, highly cross-linked polyethylene acetabular cups
A new 2-D radiographic wear measurement system has been developed which enables the low wear of highly cross-linked polyethylene acetabular cups to be accurately and precisely measured from standard, pelvis radiographs. The software was validated using radiographic images of a measurement jig which could vary the cup orientation and simulate the effect of pelvic tilt/rotation. Wear was simulate...

Introduction The orthopaedic industry has expended significant research effort in recent years in reducing wear of UHMWPE articulating surface components. One such approach has been in the development of a heavily crosslinked polyethylene. Crosslinking for long has been known to improve the wear resistance of industrial polyethylene. Clinical experience for over 20 years and an increasing magni...
متن کاملMicro X-Ray Computed Tomography Mass Loss Assessment of Different UHMWPE: A Hip Joint Simulator Study on Standard vs. Cross-Linked Polyethylene
More than 60.000 hip arthroplasty are performed every year in Italy. Although Ultra-High-Molecular-Weight-Polyethylene remains the most used material as acetabular cup, wear of this material induces over time in vivo a foreign-body response and consequently osteolysis, pain, and the need of implant revision. Furthermore, oxidative wear of the polyethylene provoke several and severe failures. To...
متن کاملWear Behaviours and Oxidation Effects on Different UHMWPE Acetabular Cups Using a Hip Joint Simulator
Given the long-term problem of polyethylene wear, medical interest in the new improved cross-linked polyethylene (XLPE), with or without the adding of vitamin E, has risen. The main aim of this study is to gain further insights into the mutual effects of radiation cross-linking and addition of vitamin E on the wear performance of ultra-high-molecular-weight polyethylene (UHMWPE). We tested four...
