Third retraction appears for orthopedic surgeon involved in investigation, lawsuits

without comments

orthopedic reviewsIn July, we reported on the unfortunate math of Harish Hosalkar, a San Diego orthopedic surgeon who was at the center of an institutional investigation into the integrity of his data, two lawsuits and three retractions.

At the time, we were waiting on the third retraction, in the journal Orthopedic Reviews. It has now arrived.

The article was titled “Open reduction and internal fixation of displaced clavicle fractures in adolescents,” and Hosalkar wrote it with Gaurav Parikh, James D. Bomar and Bernd Bittersohl. Read the rest of this entry »

Tokyo panel calls for retraction of 43 Kato papers

without comments

katoThe University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.

If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally. His fellow countryman, Yoshitaka Fujii, continues to hold the lead at what appears to be 183, followed by Joachim Boldt (~89), John Darsee (~83), and Diederik Stapel, at 53. [See note at end.]

The Asahi report quotes Kato — who has received some $20 million in government funding for his work  — as acknowledging problems with the data in his studies: Read the rest of this entry »

Three retractions, two lawsuits, one institutional inquiry for San Diego orthopedic surgeon

without comments

11832_5_2_OC.inddThree retractions, two lawsuits, one institutional inquiry. That’s not the kind of math anyone likes to do — but it’s the tally for Harish Hosalkar, a San Diego surgeon specializing in pediatric orthopedics.

Hosalkar became embroiled in a messy affair after problems surfaced in data he had published while at Rady Children’s Hospital — a facility he left under a cloud of recriminations. More on that in a bit. Read the rest of this entry »

Lack of conflict of interest disclosure undoes scoliosis study

without comments

scoliosisThe journal Scoliosis has retracted a 2012 paper by a pair of German spine doctors over what the editors have called a less-than-fully declared conflict of interest involving one of the authors.

That should be relatively straigtforward – but it’s not quite. Turns out the article does include a disclosure, although perhaps the information it contains was incomplete.

The article, “Soft braces in the treatment of Adolescent Idiopathic Scoliosis (AIS) – Review of the literature and description of a new approach,” was written by Hans-Rudolf Weiss and Mario Werkmenn. Weiss, it seems, has something of a pedigree in the field. According to this website, he practices the “Schroth method” of recurvature, a technique pioneered by his grandmother, Katharina Schroth. From the site: Read the rest of this entry »

Post 982 — in which we find plagiarized bone graft paper that grafted from other papers

without comments

thesurgeonThe Surgeon has retracted a 2012 article by a group from the U.K. who took text from a previously published article. So, you say? Nu?

Well, we found — through relatively little effort — that the plagiarizees were themselves, shall we say, liberal in their use of material from other sources.

The retracted article was titled “Bone graft substitutes: What are the options?,” and it appeared in August 2012. One of the options, we guess, was to steal text.

According to the retraction notice: Read the rest of this entry »

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

without 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:
