Tracking retractions as a window into the scientific process

Hip, hip, retract! Cobalt poisoning case study pulled as duplicate

with 4 comments

hipinternationalHip International has retracted a case study for duplication. (We apologize for the partial duplication of a headline for an earlier post about this journal, which told readers that “Similar cases will be referred to retractionwatch.”)

The article was titled “Chronic intoxication with cobalt following revision total hip arthroplasty,” and it appeared online ahead of print. Cobalt toxicity associated with metal-on-metal replacement hips has been raised as a potential adverse effect from the devices.

As the notice explains:

The above article recently appeared ahead of print in Hip international. It subsequently became clear that many details of the case report had been published before. It is the duty of authors to submit work which has not (in whole or in part) been published elsewhere. Should published work be partially covered again, this should be acknowledged prominently, and the original publication cited. The above article was accepted because the title (and subsequent text) drew attention to cobalt toxicity. This was the reason for acceptance. The orthopaedic issues (revision to hard on hard bearings in such cases) are already well understood and would not have merited publication. Unfortunately, Hip International cannot proceed with publication of duplicated (or partially duplicated) work, and the article has been retracted.

We couldn’t find an earlier paper from this group of authors — on the same subject. But we did come across more than one case study on by other researchers on cobalt toxicity after hip arthroplasty in Muscle & Nervethe Journal of Bone and Joint Surgery and the Medical Journal of Australia.

  1. I wish the journal was more specific about where the case report was duplicated. Did the authors report their own case twice, or did they use a case from the same hospital that someone else had already reported, or did they outright plaigarize a case they never treated?

  2. Ivan, possibly this is the earlier paper by the same authors? The retracted paper is unavailable so I can’t compare clinical details.
