Quantitative Analysis of Retrieved Glenoid Liners
Revision of orthopedic surgeries is often expensive and involves higher risk from complications. Since most total joint replacement devices use a polyethylene bearing, which serves as a weak link, the assessment of damage to the liner due to in vivo exposure is very important. The failures often are due to excessive polyethylene wear. The glenoid liners are complex and hemispherical in shape an...
متن کاملWear of retrieved UHMWPE hip liners.
After the gamma-irradiation sterilization, the most widely used orthopaedic grade polymer bearing liner material for the total joint replacement, ultra-high molecular weight polyethylene (UHMWPE), degrades through the progressive in vivo oxidation. The oxidative degradation makes UHMWPE brittle and leads to reduction of its mechanical properties. In this study, the effect of the in vivo post-ir...
متن کاملComparison of conforming and nonconforming retrieved glenoid components.
The purpose of this study was to compare differences in wear performance of conforming and nonconforming glenoid designs, using clinical, radiographic, and retrieved polyethylene glenoid component outcome Sixty-three glenoids met the study criteria, and each glenoid was assigned to the conforming group (if the radii of curvature of the humeral and glenoid components were identical) or the nonco...
متن کاملObservations on retrieved glenoid components from total shoulder arthroplasty.
HYPOTHESIS Polyethylene components retrieved at revision of total knee and hip replacements have been analyzed to study the effect of design, patient, and surgical factors on initial implant performance, but few studies have reported similar types of findings in retrieved glenoids. MATERIALS AND METHODS From 1979 to 2006, 78 glenoid components were retrieved from revision surgery in 73 patien...
متن کاملDigital photogrammetry for quantitative wear analysis of retrieved TKA components.
The use of new materials in knee arthroplasty demands a way in which to accurately quantify wear in retrieved components. Methods such as damage scoring, coordinate measurement, and in vivo wear analysis have been used in the past. The limitations in these methods illustrate a need for a different methodology that can accurately quantify wear, which is relatively easy to perform and uses a mini...
