Quantification of structural changes of UHMWPE components in total joint replacements
BACKGROUND At present time the number of implantations of joint replacements as well as their revisions increases. Higher demands are required on the quality and longevity of implants. The aim of this work was to determine the degree of oxidative degradation and the amount of free/residual radicals in selected ultra-high molecular weight polyethylene (UHMWPE) components of the joint replacement...
متن کاملNotch fatigue of ultrahigh molecular weight polyethylene (UHMWPE) used in total joint replacements.
Ultrahigh molecular weight polyethylene (UHMWPE) has remained the primary polymer used in hip, knee and shoulder replacements for over 50 years. Recent case studies have demonstrated that catastrophic fatigue fracture of the polymer can severely limit device lifetime and are often associated with stress concentration (notches) integrated into the design. This study evaluates the influence of no...
متن کاملAntibiotic prophylaxis after total joint replacements.
OBJECTIVES To review the latest evidence on antibiotic prophylaxis for patients with total joint replacements to prevent prosthesis infections. DATA SOURCES Literature search of Medline and PubMed until June 2009. STUDY SELECTION Studies of patients with total joint replacements from around the world, studies concerning antibiotic prophylaxis, as well as chemoprophylaxis guidelines from ort...
متن کاملIncidence of metal sensitivity in patients with total joint replacements.
Sensitivity to chromium, cobalt, nickel, molybdenum, vanadium, and titanium was studied by patch tests in 50 patients who had received total joint replacements. Nineteen (38%) were sensitive to one or more of the metals. In 23 patients non-traumatic failure of the prosthesis had occurred, and 15 of these patients were sensitive to metal. Out of 27 patients with no evidence of prosthesis looseni...
متن کاملThe risk of haematogenous infection in total joint replacements.
One thousand patients who received 1112 total joint replacements between 1966 and 1980 were followed up prospectively for an average of six years. These patients were not advised to take antibiotics prophylactically to cover subsequent dental or surgical procedures and, so far, only three cases of haematogenous infection at the site of the joint replacement have developed. Two hundred and twent...
