Event Description
Early failure of metal-on-metal bearings in hip resurfacing and large-diameter total hip replacement a consequence of excess wear by d.J.Langton, s.S.Jameson, t.J.Joyce, n.J.Hallab, s.Natu, and a.V.F.Nargol published by the journal of bone & joint surgery on (b)(6) 2009.The article's purpose: "we sought to establish the rate of failure secondary to adverse reactions to metal debris (armd) in our patients, to identify relationships between this mode of failure and the wear rate of the prosthetic joint, and to provide a potential explanation for the increased incidence of this in women.For the purposes of this paper we therefore use the acronym ¿armd¿ as an umbrella term to describe joint failures associated with pain, a large sterile effusion of the hip and/or macroscopic necrosis/metallosis." the study was of 505 asr devices (87 of those were thrs) and 155 bhrs from 2002 to 2009(bhrs were from 2002 to april 2004 and asr was used there after).Table iii lists 17 cases of revision with patient identifiers captured in linked complaints listing descriptive findings of armd.Additionally, table iv included data from other asr revision cases without patient identifiers with reasons of revision as pain, effusion, pseudotumor and fracture (anatomical location not given).It is noted that chromium levels were in the range of 3.89 to 41.8 and cobalt 7.82 to 99.1 for the patients in this study.For histopathological examination of tissues from revision procedures of the 17 identifiable cases: "the various layers of the neo-capsule were studied.Layer 1 consists of the surface membrane and was graded as type 1 to 4.17 type 1 surfaces have an intact pseudosynovial membrane.Type 2 surfaces show a loss of the pseudosynovial membrane.Type 3 surfaces are associated with fibrin deposition in addition to the loss of the surface membrane, and in type 4 there is gross disruption of the surface membrane with fibrin deposition and fissuring.Layer 2 is the subsynovial layer, which usually contains the inflammatory infiltrate.Layer 3 is the vascular layer, which contains the perivascular lymphocytic cuffing.Layer 4 is the deeper layers containing muscle fat and fibrous tissue.The thickness of the histiocyte band containing particulate matter in layer 2 was measured using the graticule.The presence of perivascular lymphocytic cuffing and its average thickness in layer 3 was also recorded." impacted products: asr & asr xl.Adverse events: surgical intervention, foreign body reaction, soft tissue necrosis, pain, hypersensitivity, blood heavy metal increased.
