“…Osteolysis has been previously associated with titanium particles [11] and cobalt ions [12], but is likely underestimated with plain radiographs versus computerized tomography (CT) scans [12]. In one of our patients who did have a CT scan (patient 2), osteolysis was not noted.…”

“…In another study, Desy et al reported that a smaller ASR cup diameter was associated with higher levels of Cr and Co, as well as with larger acetabular inclination [16]. Randelli et al also found that a cup inclination angle greater than 50° led to increased concentrations of metal ions, although this angle was only present in three of their patients [17]. The study by de Haan et al similarly observed a greater release of metal ions with abduction angles above 55° [18].…”

The prognosis associated with the DePuy ASR hip cup is poor and varies according to the series. This implant was withdrawn from use in 2010 and all patients needed to be assessed. We present the results of the assessment of our patients treated with this device, according to the Spanish Society of Hip Surgery (SECCA) algorithm published in 2011. This retrospective study evaluates 83 consecutive ASR cups, followed up at a mean of 2.9 years. Serum levels of chromium and cobalt, as well as the acetabular abduction angle, were determined in order to assess their possible correlation with failure, defined as the need for revision surgery. The mean Harris Hip Score was 83.2 (range 42–97). Eight arthroplasties (13.3%) required revision due to persistent pain and/or elevated serum levels of chromium/cobalt. All the cups had a correct abduction angle, and there was no correlation between elevated serum levels of metal ions and implant failure. Since two previous ASR implants were exchanged previously to the recall, the revision rate for ASR cups in our centre is 18.2% at 2.9 years.

“…Si une de ces trois investigations s'avère anormale, des examens complé-mentaires doivent être effectués, par exemple une échographie, et des visites de contrôle supplémentaires doivent être programmées [9,35]. Le taux de cobalt circulant est donc un critère unanimement reconnu pour le suivi des patients porteurs de PHMM, même si à lui seul il ne permet pas de décider d'une reprise chirurgicale [31,33] …”

“…Ainsi, sur 14 patients ayant subi une reprise chirurgicale de leur PHMM, 7 présentaient une ostéolyse sévère accompagnée d'un taux de cobalt sanguin moyen égal à 147 μg/l. Parmi ces 7 patients, 5 étaient asymptomatiques et la radiographie était sans anomalie chez 6 d'entre eux [33]. Le dosage du cobalt dans le sang peut être envisagé de deux façons différentes, par spectrométrie de masse avec source d'ionisation par plasma induit haute fré-quence (ICP-MS), une méthode considérée comme la référence, qui présente une meilleure sensibilité et un temps d'analyse plus court, et par spectrométrie d'absorption atomique électrothermique (SAA-four).…”
